Triacs datasheet and documents for QJ4004V4TP

QJ4004V4TP

Triacs Overview

The Littelfuse QJ4004V4TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 4 A. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-252-3 surface-mount package. Key electrical characteristics include a maximum on-state voltage of 1.4 V, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 25 mA. Leakage current at VDRM is specified at 5 uA.

Triacs Feature Summary

Provides bidirectional switching capability for alternating current circuits
Engineered with high thermal stability for operation up to 150°C
Utilizes a compact surface-mount form factor for automated assembly

Triacs Applications

Solid-state relay modules
Lighting dimmer controls
Motor speed regulation systems

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid manufacturer traceability. Confirm RoHS compliance status through the latest datasheet revision before finalizing orders.

Triacs Selection Notes

Select this component when a 400 V rating and 4 A continuous current capacity are required in a surface-mount configuration. Consider the 1.3 V gate trigger threshold for driver compatibility. Evaluate thermal management requirements given the 150°C maximum junction temperature limit.

Triacs Part Context

This part belongs to the QJxx04xx series of standard triacs manufactured by Littelfuse. The series is characterized by robust construction suitable for general-purpose AC power switching. It shares common design principles with other devices in the family but is distinguished by its specific voltage and current ratings.
