Thyristors 20 Amps High Junction Temperature SCRs RoHS SVxx20xx Series Description This SVxx20xx 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 or 10 mA maximum at approximately 1.5 V. Features & Benefits Halogen free and RoHS Surge capabilit y up to compliant 300A at 60 Hz half cycle 150 C maximum junction High dv/dt performance temperature Schematic Symbol Main Features Symbol Value Unit AK I 20 A T(RMS) V /V 600 V DRM RRM G I 6 or 10 mA GT Applications Typical applications include AC Generator (ACG) rectifiers, battery voltage regulators, generic converters and inrush current controller in various AC to DC applications. Additional applications include controls for power tools, home/brown good and white goods appliances. Internally constructed isolated packages offered for ease of heat sinking with high isolation voltage.
