Q4006R4TP

Triacs Overview

The Littelfuse Q4006R4TP is a bidirectional triac 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 (Ih) of 50 mA, a gate trigger voltage (Vgt) of 2.5 V, and a gate trigger current (Igt) ranging from 25 mA to 50 mA. The on-state voltage is specified at 1.6 V, with non-repetitive peak on-state currents of 65 A or 80 A depending on the pulse duration. Leakage current in the off-state is limited to 50 uA at VDRM.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount installation via SMTO-263-2 package
• High thermal stability across extended operating temperatures

Triacs Applications

• Solid-state relays
• Motor speed control circuits
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix 'R4TP' against the manufacturer's official datasheet to confirm pinout orientation and packaging type. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Triacs Selection Notes

Select this component when a 6 A RMS current rating and 400 V blocking voltage are required in a surface-mount form factor. Consider the gate trigger characteristics and holding current limits relative to the driving circuit capabilities. Evaluate thermal management needs given the SMTO-263-2 package constraints for the intended application environment.

Triacs Part Context

This triac belongs to the Littelfuse Qxx06xx series, which provides standardized AC power switching solutions. The Q4006R4TP variant specifically offers surface-mount convenience compared to through-hole alternatives like the Q4006L4TP. It serves as a compact replacement for legacy TO-220 packages in space-constrained designs requiring similar electrical performance.

Triacs Replacement Considerations

Direct substitutes include the Q4006N4RP and Q4006L4TP, provided pin configurations and package types match the design requirements. Verify that alternative parts maintain equivalent voltage and current ratings to ensure circuit compatibility without redesign.
