Q6006RH4TP

Triacs Overview

The Littelfuse Q6006RH4TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 6 A. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The non-repetitive peak on-state current is specified at 80 A or 85 A depending on the pulse width. The component utilizes a TO-220-3 package with an isolated tab for mounting.

Triacs Feature Summary

• Integrated Alternistor technology for high reliability and robust performance in AC switching circuits
• Sensitive gate structure enabling direct interfacing with microprocessors and logic circuits
• High thermal stability supporting operation up to 125 °C junction temperature

Triacs Applications

• Solid-state relays and motor speed controls
• Lighting dimmers and soft-start circuits
• General-purpose AC load switching

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against the manufacturer's latest datasheet to confirm pinout orientation and packaging details. Ensure the procurement channel provides original Littelfuse documentation to validate RoHS compliance and traceability. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 6 A continuous current rating are required for AC loads. The sensitive gate drive characteristics simplify circuit design by reducing gate drive power requirements. Consider the TO-220-3 package size for through-hole mounting constraints and thermal dissipation needs in the target application.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xxH series of Alternistor TRIACs. These devices combine high surge capability with standard gate sensitivity. The series is engineered for industrial and consumer AC power control applications requiring reliable switching and long operational life under varying thermal conditions.

Triacs Replacement Considerations

Direct replacements include the Q6006LH4TP and Q6006DH4. Verify that substitute packages match the mechanical footprint and thermal interface requirements of the existing design.
