Thyristors 12 Amp Standard SCRs RoHS Sxx12x Series Description This Sxx12x 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 20 mA at approximately 1.5V. Features & Benefits Halogen free and V oltage capability up to 1000 V RoHS compliant Surge capability up to 120 Glass passivated A at 60 Hz half cycle junctions Agency Approval Electrically isolated L-Package is UL Agency Agency File Number recognized for 2500Vrms L Package: E71639 Main Features Applications Typical applications includes capacitive discharge system Symbol Value Unit for motorcycle engine CDI, portable generator engine I 12 A ignition, strobe lights and nailers, as well as generic T(RMS) rectifiers, battery voltage regulators and converters. Also V /V 400 to 1000 V DRM RRM AC control & rectification for power tools, home/brown goods, white goods appliances and 2-wheeler rectifier/ I 20 mA GT battery regulators. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
