The Littelfuse Inc. SK025R is a standard recovery SCR offering a repetitive peak off-state voltage of 1 kV. This through-hole component features a non-isolated TO-220 package with a maximum on-state current of 25 A RMS (16 A average). It exhibits a gate trigger current (IGT) of 35 mA maximum and a hold current (IH) of 50 mA maximum. The non-repetitive surge current (ITSM) reaches 300 A at 50 Hz and 350 A at 60 Hz. The off-state current is a mere 20 µA maximum, with a maximum on-state voltage (VTM) of 1.6 V and a gate trigger voltage (VGT) of 1.5 V maximum. Operating temperature ranges from -40°C to 125°C. This device is commonly utilized in power control applications across industrial and automotive sectors.
