Triacs datasheet and documents for Q4016LH3TP

Q4016LH3TP

Triacs Overview

The Q4016LH3TP is a 400V, 16A bidirectional triac from Littelfuse's Qxx16xHx series. It features a snubberless design with an on-state voltage of 1.6V and off-state leakage current of 5uA at VDRM. The device operates within a temperature range of -40°C to +125°C. It utilizes a TO-220-2 package for through-hole mounting. Key electrical parameters include a holding current maximum of 50mA, gate trigger voltage of 2V, and gate trigger current of 20mA.

Triacs Feature Summary

Snubberless operation capability
High thermal stability up to 125°C
Low on-state voltage drop

Triacs Applications

Lighting control systems
Motor speed regulation
Heating element control

Triacs Procurement Notes

Verify the specific suffix 'H3TP' against official Littelfuse documentation to confirm the exact gate trigger current specifications (20mA) and package variant. Ensure compatibility with existing PCB footprints for the TO-220-2 configuration. Cross-reference datasheet revisions to confirm compliance with current environmental standards such as RoHS and REACH requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component for applications requiring robust AC power switching with minimal external snubber circuitry. The 16A RMS rating suits moderate load control tasks. Consider the TO-220-2 package for efficient heat dissipation in space-constrained designs. Verify that the 20mA gate trigger current aligns with the driving circuit's output capabilities to ensure reliable turn-on under all operating conditions.

Triacs Part Context

This part belongs to the Qxx16xHx family of high-performance triacs designed for industrial and consumer applications. The series emphasizes reliability and ease of use by eliminating the need for complex snubber networks. These devices are engineered to handle repetitive peak currents effectively while maintaining stable performance across wide temperature variations typical in electronic control environments.
