Q4006RH3TP

Triacs Overview

The Littelfuse Q4006RH3TP is a bidirectional triac designed for AC power control applications. It features a rated on-state RMS current (IT(RMS)) of 6 A and a repetitive peak off-state voltage (VDRM) of 400 V. The device operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a maximum on-state voltage of 1.6 V, a holding current (IH) of up to 15 mA, and gate trigger parameters of 1.3 V and 10 mA respectively. Non-repetitive surge currents are rated at 55 A and 65 A under different conditions.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Robust thermal performance with high junction temperature tolerance
• Low on-state voltage for efficient power handling

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'H3TP' against official Littelfuse documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the 400V voltage rating aligns with circuit requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before procurement.

Triacs Selection Notes

Select this component when a 6A RMS current capacity and 400V blocking voltage are required for AC load switching. Consider the TO-220 package for through-hole mounting and adequate heat dissipation. Evaluate the gate trigger current of 10 mA to ensure compatibility with the driving logic circuitry. Verify that the 1.6V on-state voltage meets efficiency targets for the specific application.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xxh series of bidirectional triacs. The series is engineered for general-purpose AC power control. The Q4006RH3TP variant specifically integrates the 400V voltage rating and 6A current handling into a standard TO-220 package, distinguishing it from higher or lower voltage/current counterparts in the same family.

Triacs Replacement Considerations

Consult Littelfuse datasheets for direct replacements within the Q400x series. Verify pinout compatibility and thermal resistance values when substituting with other manufacturers' triacs. Ensure equivalent voltage and current ratings are maintained to prevent circuit failure.
