TD3281
Random Phase Switching
800V
Triac Driver
Description
Features
Random Phase Switching
800V Blocking Voltage
The TD3281 consists of a single input AlGaAs LED
optically coupled to a Random Phase triac driver chip. The
TD3281 provides high input-to-output isolation and is
Trigger Current (15mA MAX)
High Isolation Voltage (5000VRMS
High dV/dt (1kV/S MIN)
designed to drive high-powered triacs.
Typical uses
include interfacing logic level control signals to equipment
powered from 240VAC lines and higher.
)
Long Life / High Reliability
The TD3281 comes standard in a miniature 6 pin DIP
package making it ideal for high-density board applications.
RoHS / Pb-Free / REACH Compliant
