Three high current photo relays replace mechanical devices in harsh environments

A trio of photo relays by Toshiba Electronics Europe will replace mechanical 1-Form-A relays in industrial and factory automation applications.

The TLP3106A, TLP3107A and TLP3109A are based on the latest U-MOS IX semiconductor process with a trench structure. The process has been developed to reduce on-resistance. As a result the TLP3106A, TLP3107A and TLP3109A to have Ron (max) values of 30, 40 and 65 mOhm respectively. The new photo relays offer a range of options including an off-state output terminal voltage (Voff) between 30 and 100V and a steady on-state current (Ion) between 3.0 and 4.5A. Pulsed on-state current values are in the range 9.0 to 13.5A.

All three devices offer an isolation voltage (BVS minimum) of 1500Vrms and operate across a temperature range of -40 to +110 degrees C. They are housed in a small six-pin SOP surface mount package.

1-Form-A mechanical relays are popular in DC and AC applications such as factory automation, I/O interface boards, heating ventilation and air conditioning (HVAC) equipment, security devices and measurement products. The TLP3106A, TLP3107A and TLP3109A photo relays can replace 1-Form-A relays in all of these applications, to reduce the space needed for the relays and relay drivers. They also enhance system reliability, says Toshiba.
