The YZPST-X0402 from Yangzhou Positioning Tech Co. Ltd. is a Silicon Controller Rectifier that is ideal for ground fault circuit interrupters, over-voltage crowbar protection in low power supplies, and capacitive ignition circuit applications. It has a break-over voltage of up to 600 V and a break-over current of less than 4 A. This rectifier has a gate trigger voltage of 0.8 V and a gate trigger current of 200 µA. It has highly sensitive triggering levels, which makes it suitable for applications where the available gate current is limited. The Silicon rectifier is available in a through-hole package that measures 10 x 20.2 mm.
