Vishay Intertechnology Launches New Non-Zero Crossing
Phototriac Optocouplers in Compact, Environmentally Green
MALVERN, Pa. - June 11, 2012 - Vishay Intertechnology, Inc.
(NYSE: VSH) is broadening its optoelectronics portfolio
with the release of new non-zero crossing phototriac
optocouplers in the industry-standard miniflat SOP-4
package, saving up to 66 % in PCB space compared to devices
in the DIP-6 package.
The new VOM160 and VOM305x series offer three choices
of input trigger LED current: 5 mA (VOM160NT / VOM3053T), 7 mA (VOM160PT), and 10 mA (VOM160RT / VOM3052T). With a package height of
only 2.0 mm, they feature a blocking voltage of 600 V AC
for high-voltage applications.
In consumer applications, the VOM160 and VOM305x series will be used for
turning on and off motors and solenoid control in
refrigerators, washers, lamps and coffee makers. The new
devices will also be used to drive TRIACs for solid-state
relays and static AC power switches in industrial
The VOM3052T and VOM3053T, with their high static
dV/dt of 1500 V/µs, are particularly well suited 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
