The devices’ hybrid architecture enables fast typical turn-on and turn-off times of 0.20ms and 0.03ms and ambient temperature range of -40°C to 100°C.
Vishay Intertechnology's VOR1121A6, VOR1121B6, VOR2121A8 and VOR2121B8 are hybrid solid-state relays that provide faster, bounce-free switching and a wider operating temperature range, and are more cost-effective.
These relays are single-channel (VOR1121A6 and VOR1121B6) and dual-channel (VOR2121A8 and VOR2121B8) normally open single-pole, single-throw (SPST) switches. The devices’ hybrid architecture enables fast typical turn-on and turn-off times of 0.20ms and 0.03ms, and an ambient temperature range of -40°C to 100°C. A high-efficiency GaAIAs IRED enables low forward current on the input side. On the output side, high-performance MOSFET switches provide low on-resistance of 12Ω to reduce power dissipation. The VOR1121A6 and VOR1121B6 can be figured for DC-only operation to reduce the on-resistance.
The VOR1121A6 and VOR2121A8 are offered in DIP-6 and DIP-8 packages, respectively, while the VOR1121B6 and VOR2121B8 feature the SMD-6 and SMD-8. All four devices offer a high isolation test voltage of 5300VRMS and load voltages of 250V. The solid-state relays are VDE- and UL-certified as well as RoHS-compliant, meaning the devices meet the insulation requirements for telecommunications, industrial, security system and metering applications. Typical applications will include alarm and telecom switches, I/O cards, automation, battery management systems and automatic test equipment.
