VO4256

Note
Tamb = 25 , unless otherwise specified

Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute Maximum Rating for extended periods of the time can adversely affect reliability.

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 of VO4254/VO4256  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/s 

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.
