Thyristors 8 Amp Sensitive & Standard SCRs RoHS Sxx08xSx & Sxx08x Series Description This Sxx08x 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 500A. The sensitive gate SCR version is easily triggered by sense coils, proximity switches, and microprocessors. Agency Approval Features & Benefits Halogen-free and Surge capability up Agency Agency File Number RoHS-compliant to 100 A at 60 Hz E71639* half cycle Glass passivated * - L Package Only junctions L - Package is UL Recognized for 2500Vrms V oltage capability up to 1000 V Main Features Applications Typical applications are capacitive discharge systems for Symbol Value Unit strobe lights, nailers, staplers and gas engine ignition. Also I 8 A T(RMS) AC control & rectification for power tools, home/brown V /V 400 to 1000 V DRM RRM goods, white goods appliances and 2-wheeler rectifier/ I 0.2 to 15 mA GT battery regulators. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
