Sxx65x & Sxx70x Series

65 / 70 Amp Standard SCRs

Sxx65x & Sxx70x Series

Description

Excellent unidirectional switches for phase control

applications such as heating and motor speed controls.

Standard phase control SCRs are triggered with few

milliamperes of current at less than 1.5V potential.
