DESCRIPTION
The VO4257, 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.
APPLICATIONS
• Solid-state relays
• Industrial controls
• Office equipment
• Consumer appliances
AGENCY APPROVALS
• UL1577, file no. E52744 system code H or J, double
protection
• CUL - file no. E52744, equivalent to CSA bulletin 5A
• DIN EN 60747-5-5 (VDE 0884) available with option 1
