Thyristors 20 / 25 Amp Standard SCRs 20 Amps High Junction Temperature SCRs RoHS SJxx20xx Series Description This SJxx20xx high temperature SCR series is ideal for uni-directional switch applications such as phase control in heating, motor speed controls, converters/rectifiers and inrush current controllers. These SCRs have a low gate current trigger level of 6 mA,10 mA or 35 mA maximum at approximately 1.5 V. Features & Benefits Halogen free and R oHS Surge capability up to compliant 300A at 60 Hz half cycle 150 C maximum junction temperature Schematic Symbol Applications Typical applications include AC Generator (ACG) rectifiers, AK battery voltage regulators, generic converters and inrush current controller in various AC to DC applications. Additional applications include controls for power tools, G home/brown good and white goods appliances. Isolated packages offered for ease of heat sinking.
