Product Description
Product Description
The Sxx08x SCR series is designed for uni-directional switch applications including phase control, heating, motor speed controls, converters/rectifiers, and capacitive discharge ignitions. These SCRs feature a low gate current trigger level (0.2 to 15 mA at approximately 1.5V). The sensitive gate versions offer an even lower gate trigger current (< 500A), making them easily triggered by sense coils, proximity switches, and microprocessors. Internally constructed isolated packages are available for simplified heat sinking with enhanced isolation voltage.
