High-speed photo relays from Toshiba now at Rutronik
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 % to 150 µs while maintaining signal quality.
In addition, the 20% smaller S-VSON4T package saves valuable space on the circuit board. These performance features make the relays the ideal choice 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 even only 1.2 Ω. The 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 for the TLP3414S and 20 V / 450 mA for the TLP3431S.
Both photo relays are encased in the space-saving S-VSON4T housing with dimensions of just 1.45 mm × 2.0 mm × 1.3 mm. This not only supports the miniaturisation of modern test systems but also improves thermal and electrical performance thanks to shorter signal paths.
