L401E5RP

Triacs Overview

The L401E5RP is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 1 A. The device utilizes a sensing gate structure with a sensitivity range of 5 mA to 5 mA, facilitating reliable triggering in low-power drive circuits. Packaged in the SMTO-263-2 surface-mount format, it supports operation within a junction temperature range of -40°C to +125°C. This component is suitable for integration into compact electronic designs requiring robust AC switching capabilities.
