DESCRIPTION
The VO4254/VO4256 phototriac consists of a GaAs IRLED
optically coupled to a photosensitive non-zero crossing
TRIAC packaged in a DIP-6 package.
High input sensitivity is achieved by using an emitter follower
phototransistor and a cascaded SCR predriver resulting in
an LED trigger current of 1.6 mA for bin D, 2 mA for bin H,
and 3 mA for bin M.
The new non zero phototriac family use a proprietary dV/dt
clamp resulting in a static dV/dt of greater than 5 kV/µs.
The VO4254/VO4256 phototriac isolates low-voltage logic
from 120, 240, and 380 VAC lines to control resistive,
inductive, or capacitive loads including motors, solenoids,
high current thyristors or TRIAC and relays.
