Optocoupler, Phototriac Output, High dV/dt, Low Input Current

DESCRIPTION

The VO4254 and 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 and VO4256 phototriac isolates low-voltage

resistive, inductive, or capacitive loads including motors,

solenoids, high current thyristors or TRIAC and relays.

FEATURES

• High static dV/dt 5 kV/μs

• High input sensitivity 1.6 mA, 2 mA, and 3 mA

• 400 V and 600 V blocking voltage

• 300 mA on-state current

• Material categorization:
