Q4006N4TP

Triacs Overview

The Q4006N4TP is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state 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 holding current of 50 mA, a gate trigger voltage of 2 V, and a gate trigger current of 35 mA. The on-state voltage drop is specified at 1.6 V, with a non-repetitive peak on-state current capability of 67 A. It is housed in a surface-mount SMTO-263-2 package.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount construction for automated assembly
• High thermal stability across extended operating temperatures

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'N4' against the manufacturer's official datasheet to confirm pinout configuration and packaging details. Ensure compatibility with existing PCB footprints before ordering. Confirm RoHS compliance status through the latest Littelfuse documentation. Request sample units for initial circuit validation prior to bulk procurement.

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. Compare the 35 mA gate trigger current against available drive circuit capabilities. Evaluate thermal management requirements given the SMTO-263-2 package constraints. Consider the 1.6 V on-state voltage for power dissipation calculations in high-duty cycle applications.

Triacs Part Context

This part belongs to the Qxx06xHx series of triacs from Littelfuse, which are engineered for general-purpose AC power switching. The series offers various voltage ratings and package options to suit different industrial and consumer electronics needs. The Q4006N4TP specifically targets applications requiring moderate current handling with robust surge tolerance.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified equivalents. Potential substitutes may include other 400 V, 6 A triacs in TO-220 or SMD packages. Verify that any replacement matches the gate trigger characteristics and thermal resistance specifications.
