Description
This Sanken triac (bidirectional triode thyristor) is designed
for AC power control, providing reliable, uniform switching
for full-cycle AC applications.
In comparison with other products on the market, the TMB20x
series provides increased isolation voltage (1800 VAC
RMS
),
guaranteed for up to 1 minute, and greater peak nonrepetitive
off-state voltage, V
DSM
(700 V). In addition, commutation
dv/dt and (dv/dt)c are improved.
Package: 3-pin SIP (TO-220F)
Applications
▪
Residential and commercial appliances: vacuum cleaners,
rice cookers, TVs, home entertainment
▪
White goods: washing machines
▪
Office automation power control, photocopiers
▪
Motor control for small tools
▪
Temperature control, light dimmers, electric blankets
▪
General use switching mode power supplies (SMPS)
