High-speed photo relays optimised for semiconductor test

Rutronik has introduced Toshiba’s TLP3414S and TLP3431S, new high-speed photo relays for semiconductor testing. Improved infrared LEDs and optimised photodiode arrays in these models enable switch-on times to be reduced by up to 62 per cent to 150 µs while maintaining signal quality. This significantly increases efficiency in test systems.

In addition, the 20 per cent smaller S-VSON4T package saves space on the circuit board. These performance features make the relays ideal for pin electronics applications in semiconductor testers that require high switching speeds and precise signal control.

The TLP3414S has a maximum switch-on resistance of 3 Ω, the TLP3431S only 1.2 Ω. Typical output capacitance of both variants is 6.5 pF, a decisive factor in reducing high-frequency signal losses when switched off. The voltage and current values in the ON and OFF phases are 40 V/250 mA (TLP3414S) and 20 V/450 mA (TLP3431S).
