K2400GAP

DIACs, SIDACs Overview

The Littelfuse K2400GAP is a high-voltage trigger diode (SIDAC) from the Kxxxzy series, designed for breakover and pulse-trigger applications. It features a bidirectional structure with a breakover voltage range of 220 V to 250 V at 10 µA. The device supports a maximum repetitive off-state voltage of 190 V and an RMS on-state current of 1 A. Non-repetitive peak currents reach up to 20 A. It operates within a temperature range of -40°C to +85°C and is housed in a DO-15 through-hole package.
