Thyristors 10 Amp Sensitive & Standard SCRs Sxx10xSx & Sxx10x Series RoHS Description This Sxx10x SCR series is ideal for uni-directional switch applications such as phase control, heating, motor speed controls, converters/rectifiers and capacitive discharge ignitions. These SCRs have a low gate current trigger level of 0.2 to 15 mA at approximately 1.5V, with a sensitive version of this series having a gate trigger current less than 500µA. The sensitive gate SCR version is easily triggered by sense coils, proximity switches, and microprocessors. Features & Benefits • Halogen free and RoHS • Voltage capability up compliant to 1000 V Main Features • Glass – passivated • Surge capability up junctions to 100 A at 60 Hz Symbol Value Unit half cycle I 10 A T(RMS) V /V 400 to 1000 V DRM RRM I 0.2 to 15 mA Applications GT Typical applications includes capacitive discharge system for motorcycle engine CDI, portable generator engine ignition, strobe lights and nailers, as well as generic Additional Information rectifiers, battery voltage regulators and converters. Also AC control & rectification for power tools, home/brown goods, white goods appliances and 2-wheeler rectifier/ battery regulators. Internally constructed isolated packages are offered for Datasheet Resources Samples ease of heat sinking with highest isolation voltage. Schematic Symbol A K G © 2018 Littelfuse, Inc.
