Description

This Sanken reverse blocking triode thyristor is designed for

AC power control, providing reliable, uniform switching for

half-cycle AC applications.

In comparison with other products on the market, the TFA3x

guaranteed for up to 1 minute. In addition, commutation

dv/dt is improved.

Typical Applications

M

Single-phase motor control (for example, electric tool)

In-rush current control (for example, SMPS)
