Thyristors 20 / 25 Amp Standard SCRs 25 Amps High Junction Temperature SCRs RoHS SVxx25xx Series Description This SVxx25xx 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 6mA or 10mA maximum at approximately 1.5 V Features & Benefits Halogen free and RoHS Surge capability up to compliant 350 A at 60 Hz half cycle 150C maximum junction High dv/dt performance temperature Schematic Symbol Main Features Symbol Value Unit AK I 25 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, inrush current controller in various AC to DC applications and soft starter for low power AC motor. 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.
