TMB20x Series
Triac (Bidirectional Triode Thyristor)
Features and Benefits
▪ Exceptional reliability
▪ Small fully-molded SIP package with heatsink mounting
for high thermal dissipation and long life
▪ VDRM of 600 V
▪ 20 ARMS on-state current
▪ Uniform switching
▪ UL Recognized Component (File No.: E118037) (suffix I)
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 VACRMS),
guaranteed for up to 1 minute, and greater peak nonrepetitive
off-state voltage, VDSM (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)
