Quality Control: Learn More
The Littelfuse Inc. SK255KDTP is a standard recovery SCR (Silicon Controlled Rectifier) designed for robust power control applications. This through-hole component features a high blocking voltage of 1.2 kV and a significant on-state current handling capability, with a maximum RMS on-state current of 55 A and an average on-state current of 35 A. The device exhibits a low off-state leakage current of 10 µA and requires a gate trigger voltage of 1.5 V with a gate trigger current of 50 mA for reliable turn-on. The SK255KDTP is housed in a TO-218AC package, facilitating efficient thermal management in demanding environments, and operates within a temperature range of -40°C to 125°C. This SCR is commonly utilized in power switching, motor control, and industrial power supply systems.
