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
series provides increased isolation voltage (1800 VAC_RMS),
guaranteed for up to 1 minute. In addition, commutation
dv/dt is improved.
Package: 3-pin SIP (TO-220F)
Applications
▪ Motor control for small tools
▪ Temperature control, light dimmers, electric blankets
▪ General use switching mode power supplies (SMPS)
Not to scale
