Q4006NH4TP

Triacs Overview

The Littelfuse Q4006NH4TP 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 6 A. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current (Igt) of 35 mA, a gate trigger voltage (Vgt) of 2 V, and a holding current (Ih) of 50 mA. It exhibits an on-state voltage of 1.6 V and a non-repetitive peak on-state current ranging from 55 A to 65 A. The component utilizes an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• High thermal stability with a maximum operating temperature of 125°C
• Logic-level sensitivity requiring a maximum gate trigger current of 35 mA
• Robust surge handling capability with peak currents up to 65 A

Triacs Applications

• Solid-state relay circuits
• AC motor speed control systems
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and packaging variations. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification reports before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 400 V rating and 6 A continuous current are required in a compact surface-mount form factor. Ensure the driving circuit can supply at least 35 mA to guarantee reliable triggering across the specified temperature range.

Triacs Part Context

This part belongs to the Qxx06xxHx series of high-sensitivity triacs from Littelfuse. It shares the 6 A current rating with other variants but differs in gate sensitivity and package type compared to standard logic-level or higher-current models in the broader product line.

Triacs Replacement Considerations

Direct substitutes include the Q4006L4TP and Q4006DH4TP. Verify that the alternative package (TO-220-2 or TO-252-3) fits the design constraints and that gate sensitivity requirements remain compatible.
