TFA5x Series
Reverse Blocking Triode Thyristor
Features and Benefits
Exceptional reliability
Small fully-molded SIP package with heatsink mounting
for high thermal dissipation and long life
Operating junction temperature to 150°C
VDRM of 700 or 800 V
7.8 ARMS on-state current
7 mA typical gate trigger current
Uniform switching
UL Recognized Component (File No.: E118037) (suffix I)
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 TFA5x
series provides increased isolation voltage (1800 VACRMS),
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
Typical Applications
M
Single-phase motor control (for example, electric tool)
28105.02, Rev. 1
In-rush current control (for example, SMPS)
