C140 and C141 Series of Silicon Controlled Rectifiers are reverse blocking

triode thyristor semiconductor devices designed primarily for high-frequency power switching

applications which require blocking voltages up to 400 volts and load currents up to 35 amperes

RMS, at frequencies up to 25 kHz.

For line commutated applications (phase control, AC switching) at power line frequencies, up

to 35 amperes RMS, the following preferred SCR types are recommended: C35 (Pub. #160.20),

and C137 (Pub. #160.45).

The C140 and C141 Series feature:

• Contoured junction surfaces for high-voltage stability

• Shorted emitters for high dv/dt (200V/Msec)

• Distributed gates for high di/dt (400A//*sec)

Equipment designers can use the C140 and C141

SCR's in demanding applications such as:

• Choppers

• Inverters

• Regulated power supplies

• Cycloconverters

• Ultrasonic generators

• High frequency lighting

• Sonar transmitters

• Induction heaters

• Radio transmitters
