Triacs datasheet and documents for Q4010L4

Q4010L4

Triacs Overview

The Littelfuse Q4010L4 is a bidirectional triac 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 10 A. The device operates within a temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 100 A or 120 A depending on the specific test condition. Leakage current in the off-state is limited to 10 uA at VDRM.

Triacs Feature Summary

Bidirectional switching capability for AC load control
High thermal stability operating up to 125 °C
Robust surge current handling for inductive loads

Triacs Applications

AC motor speed control circuits
Solid-state relay implementations
Lighting dimmer switches

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets as regulatory requirements may vary by production batch. Check for end-of-life notices regarding discontinuation schedules to ensure long-term supply chain stability for production planning.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 10 A continuous current rating are required for AC switching. Ensure the gate drive circuit can provide at least 25 mA trigger current. Verify that the TO-220-2 package fits the thermal and spatial constraints of the target PCB design compared to alternative thyristor packages.
