Semiconductor hybrid SSRs distributed through New Yorker Electronics

Compared to similar solutions, the Vishay Semiconductors 1 Form A VORs provide faster operation with TON 0.20ms and TOFF 0.03ms, a wide temperature range of -40 to +100°C and a higher load voltage of 250V.

The VOR1121A6 and VOR1121B6 are single-channel SSRs and the VOR2121A8 and VOR2121B8 are dual-channel SSRs. They are both 250V normally open, optically isolated SSRs that have single-pole, single-throw (SPST) switches (1 form A).

They are both are based on hybrid architecture which allows for faster switching times with a wide operating ambient temperature range. A highly efficient GaAlAs IRED enables low forward current on the input side. On the output side, high performance MOSFET switches provide a low RON and can switch both DC and AC signals.
