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
logic from 120 V
AC
, 240 V
AC
, and 380 V
AC
lines to control
resistive, inductive, or capacitive loads including motors,
solenoids, high current thyristors or TRIAC and relays.
FEATURES
• High static dV/dt 5 kV/μs
