S4040N - 40Amp Standard SCR

Download the S4040N datasheet PDF. This datasheet also covers the S4040R variant, as both devices belong to the same 40amp standard scr family and are provided as variant models within a single manufacturer datasheet.

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.
