K2500F1

DIACs, SIDACs Overview

The Littelfuse K2500F1 is a high-voltage trigger diode, classified as a SIDAC, designed for robust circuit protection. It operates within a breakover voltage range of 240 V to 280 V and supports a maximum holding current of 150 mA. The device features a low on-state voltage of approximately 1.5 V and handles non-repetitive peak currents up to 20 A. Rated for a continuous RMS current of 1 A, it utilizes a DO-15 through-hole package. The component functions reliably across an operating temperature range from -40°C to +85°C.
