• Compliant to RoHS Directive 2011/65/EU
DESCRIPTION
The VO4257 and VO4258 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 VO4257, VO4258 phototriac isolates low-voltage logic
from 120 VAC, 240 VAC, and 380 VAC lines to control
resistive, inductive, or capacitive loads including motors,
solenoids, high current thyristors or TRIAC and relays.

Note
• The thermal characteristics table above were measured at 25 °C and the thermal model is represented in the thermal network below. Each
resistance value given in this model can be used to calculate the temperatures at each node for a given operating condition. The thermal
resistance from board to ambient will be dependent on the type of PCB, layout and thickness of copper traces. For a detailed explanation
of the thermal model, please reference Vishay's Thermal Characteristics of Optocouplers application note.
