Non-zero crossing phototriac optocouplers from Vishay in SOP-4 package

Vishay Intertechnology, Inc. has released the new non-zero crossing phototriac optocouplers in the industry-standard miniflat SOP-4 package that saves up to 66 % in PCB space compared to devices in the DIP-6 package.

Features:
1. Three choices of input trigger LED current: 5 mA (VOM160NT / VOM3053T), 7 mA (VOM160PT), and 10 mA (VOM160RT / VOM3052T)
2. Package height: 2.0 mm
3. Blocking voltage: 600 V AC

The VOM160 and VOM305x series can be used in consumer applications for turning on and off motors and solenoid control in refrigerators, washers, lamps and coffee makers. The new devices can be used to drive TRIACs for solid-state relays and static AC power switches in industrial applications.

The VOM3052T and VOM3053T have high static dV/dt of 1500 V/µs and are suitable for noisy environments where a lower dV/dt can cause a thyristor to be triggered as a result of a high slew rate transient on the output load, even without any triggering signal on the input.

Brief Specifications Table:
Device Trigger current IFT(mA) Minimum critical rate of rise off-state voltage dV/dt (V/µs) Maximum peak off-state voltage VDRM (V) Isolation test voltage VISO (VRMS)
VOM3053T 5 1500 600 3750
VOM3052T 10
VOM160NT 5 500
VOM160PT 7
VOM160RT 10
