QJ6004V3TP

Triacs Overview

The Littelfuse QJ6004V3TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 4 A. The device exhibits a maximum on-state voltage of 1.4 V at rated current, with a gate trigger voltage (VGT) of 1.3 V and gate trigger current (IGT) of 25 mA. Leakage current in the off-state is limited to 5 uA under VDRM conditions. It operates within a temperature range of -40 C to +150 C and is housed in a TO-252-3 surface-mount package.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount TO-252-3 package for automated assembly
• High thermal stability up to 150 C junction temperature

Triacs Applications

• Solid-state relays
• Lighting dimmers
• Motor speed controls

Triacs Procurement Notes

Verify the exact part number suffix against official Littelfuse documentation to confirm pinout and electrical specifications. Ensure the ordering code matches the required packaging format, such as cut tape or reel, as indicated in the manufacturer's datasheet. Confirm RoHS compliance status through the specific product specification sheet before integration into designs.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current rating are required for compact AC switching circuits. The TO-252-3 package is suitable for applications needing efficient heat dissipation in space-constrained layouts. Verify that the gate drive circuit can supply the specified 25 mA trigger current reliably across the operating temperature range.

Triacs Part Context

This triac belongs to the QJxx04xx series from Littelfuse, which provides standard thyristor solutions for general-purpose power control. The series offers various voltage ratings while maintaining consistent current handling capabilities. These devices are engineered for reliability in industrial and consumer electronics requiring robust AC switching performance.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified equivalent parts. Ensure any substitute maintains identical voltage, current, and package dimensions. Verify compatibility with existing gate drive requirements and thermal management constraints before implementation.
