Q2X8E3

Triacs Overview

The Q2X8E3 is a logic-level, sensitive-gate TRIAC manufactured by Littelfuse Inc. It features a 200V blocking voltage and an on-state current rating of 0.8A. The device is housed in a TO-92 package and is designed for switching and controlling AC loads. It ensures reliable gate control in Quadrants II and IV.

Triacs Feature Summary

Sensitive-gate design for direct microprocessor interface
Logic-level triggering capability
Guaranteed gate control in Quadrants II and IV

Triacs Applications

Lighting control systems
Small AC load switching
Consumer electronics AC power management

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before procurement. Confirm that the TO-92 package variant matches the required PCB layout constraints. Ensure the 200V rating is sufficient for the target AC line voltage to prevent breakdown.

Triacs Selection Notes

Select this component when low gate drive current is required for sensitive logic interfaces. The 0.8A current rating suits small AC loads. Consider higher voltage ratings if operating near mains peaks. The TO-92 package limits thermal dissipation compared to larger packages.

Triacs Part Context

This part belongs to the Littelfuse Quantum series of TRIACs. These devices are engineered for high-reliability AC switching applications. The series offers various voltage ratings from 200V to 600V. The Q2X8E3 represents the lower voltage, low-current segment of this family.
