TLP3122A
On June 22, 2018 the Toshiba Electronics Europe company provided the TLP3122A photorelay intended for automation systems of production and other industrial devices, including automation systems of buildings, security systems and the equipment for testing of semiconductor devices.
According to information provided in Toshiba company in the photorelay the MOS transistors manufactured using technology process of U-MOS IX for decrease in resistance in the included status are used. The TLP3122A photorelay is issued in the miniature SO6 body with 4 outputs, allows tension at the exit in silent state (VOFF) of 60 V, continuous current in the included status (ION) 1.4 A and a pulse current in the included status (IONP) up to 4.2 A. Standard resistance in the included status (RON) is only 0.13 Ohms, ensuring effective functioning, and current is equal in silent state to only 1 micro ampere.
The device has low values of switching time: 3 ms (tON, turn-on time) and 1 ms (tOFF, turn-off time). Insulation voltage is 3750 V (root mean square value). The photorelay is completely certified according to requirements of UL1577 standard for application in systems crucial in terms of security, emphasized in Toshiba.
The TLP3122A photorelay with a normally opened exit serves as a substitute of mechanical relays with one closing contact (1-Form-A) for the purpose of reliability augmentation of systems and economy of the space necessary for placement of the relay and their drivers. TLP3122A is expected work in the temperature range from-40 to 110 °C that allows to use it in industrial devices and to provide a temperature stock at thermal design at the level of a system.
The TLP3122A photorelay is directly compatible to the TLP3122 photorelay in traditional body 2.54SOP4. It also helps to lower a control current of a system that allows to use it as replacement of a broad spectrum of mechanical relays, noted in Toshiba.
Serial deliveries of the photorelay already began.
TLP176AM
On May 3, 2018 the Toshiba Electronics Europe company provided the photorelay in the compact SO6 body with 4 outputs for automation systems of production and other industrial devices, including the equipment for testing of semiconductor devices, a security system and automation of buildings.
In the TLP176AM photorelay the MOS transistors manufactured using modern technology process of U-MOS IX are used. Rated voltage contacts in the included status (VON) is at the weekend 60 V, and continuous current in the included status (ION) is equal 0.7 A with permissible value in a pulsed mode up to 2.1 A. Thanks to insulation voltage of 3.75 kV (root mean square value) the device has, according to the developer, the best resistance to electrostatic discharges in comparison with the issued TLP172AM. The TLP176AM photorelay is directly compatible to the former TLP172AM device both on characteristics, and on mounting dimensions, noted in Toshiba Electronics Europe.
As TLP176AM has a normally opened exit, it can be used for replacement of mechanical relays with one closing contact (1-Form-A). Replacement of mechanical relays by the photorelay increases reliability of systems and reduces necessary space for placement of the relay and their drivers, explained in the company. Thanks to the operating temperature range from-40 to 110 °C of photorelay of TLP176AM it can be used in the industrial systems and allows to provide a temperature stock at thermal design at the level of a system.
The photorelay has low values of switching time: 3 ms (tON, turn-on time) and 0.5 ms (tOFF, turn-off time). Insulation voltage is 3750 V (root mean square value). The device is issued in the compact SO6 body with 4 outputs and is certified according to requirements of UL1577 for application in systems crucial in terms of security, a podchernula in Toshiba Electronics Europe.
TLP3543A, TLP3545A, TLP3546A, TLP3556A и TLP3558A
On April 4, 2018 the Toshiba Electronics Europe company announced the beginning of deliveries of the photorelay with high load current in the DIP4 and DIP6 body. In these devices in assortment of the photorelay the MOS transistors manufactured using modern technology process of U-MOS VIII are used, noted in Toshiba.
In total five photorelays are provided: TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A. They provide the range of different values of tension at the exit in silent state (VOFF) from 30 to 200 V and a steady-state current in the included status (ION) from 0.7 to 5.0 And (the highest value in the industry for devices in the DIP6 body, according to the statement of Toshiba). Low RON values (20 megohms for the device on 30 V) provide high efficiency of work. The maximum consumed current in silent state (IOFF) makes 1 micro ampere.
According to the producer, photorelays can replace mechanical relays with one closing contact (1-Form-A) in different devices of direct and alternating current, increasing reliability of systems and reducing the space necessary for placement of the relay and their drivers. Maximum operating temperature of the relay is 110 °C that allows to provide a temperature stock at design of systems.
The rated transient/pulse current in the photorelay which are switched on a status (IONP) exceeds a steady-state current in the included status three times that increases security of systems, noted in Toshiba.
According to representatives of the company of the developer, photorelays are mainly intended for secure systems and are capable to replace mechanical relays in a broad spectrum of devices of production automatic equipment and other industrial systems, including industrial equipment, automation systems of buildings, air ventilation and air conditioning systems, the equipment for testing of semiconductor devices, the automatic test equipment and security systems.
TLP3440S и TLP3475S
On March 23, 2018 the Toshiba Electronics Europe company provided two high-speed photorelays for signal transmission having, according to the developer, the minimum installation area in the industry.
TLP3475S has low standard resistance at the exit in the included status (RON), the equal 1.1 Ohms, and have low values of switching time: 0.5 ms (turn-on time) and 0.4 ms (turn-off time). Allowable voltage in the switched-off status (VOFF) is 60 V, and the maximum current is equal in the included status (ION) to 0.4 A. The device is issued in the S-VSON4 body the sizes only 2.00 mm x 1.45 mm x 1.65 mm.
TLP3440S is issued in the S-VSON4T body with the same installation area (2.00 mm x 1.45 mm), as at S-VSON4, but only 1.30 mm thick. TLP3440S has low RON (standard value of only 12.0 Ohms) and rated values of VOFF and max. current in the included status of ION of 40 V and 0.12 A respectively. Values of switching time are 0.2 ms (turn-on time) and 0.3 ms (turn-off time).
In the switched-off status both devices consume only 1 on (IOFF value). Ustanovochnaya Square of new photorelays is 22.5% less, than at the existing devices in the VSON4 body. According to representatives of Toshiba Electronics Europe, when sharing the device will help to reduce the sizes of printed circuit boards in any systems, including the equipment for tests of semiconductor devices and probe payments and also when replacing mechanical relays. They can be also used in high-speed lines of signal transmission in the gigahertz range.
Unlike standard photorelays with a maximum operating temperature of 85 °C, TLP3440S and TLP3475S devices can work in the range from-40 to 110 °C, thereby simplifying design of systems, in particular when developing of the industrial and other protected equipment, noted in Toshiba Electronics Europe.
