Q6006DH4RP

Triacs Overview

The Littelfuse Q6006DH4RP is a bidirectional TRIAC (Alternistor) designed for AC power control applications. It features a 600 V rated repetitive off-state voltage (VDRM) 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 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. It exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 55 A or 65 A depending on the pulse width. The component is housed in a TO-252AA (DPAK-3/2) surface-mount package.

Triacs Feature Summary

• High reliability construction with main terminal 2 case connection for improved thermal dissipation
• Sensitive gate triggering requiring only 35 mA gate current for reliable turn-on
• Surface-mount DPAK package optimized for automated pick-and-place assembly

Triacs Applications

• Solid-state relays and motor speed controllers
• Lighting dimmers and phase control circuits
• General-purpose AC load switching in consumer appliances

Triacs Procurement Notes

Verify the specific suffix 'H4RP' against official Littelfuse documentation to confirm lead-free status and reel packaging specifications. Ensure compatibility with RoHS directives if required by the target market. Confirm that the TO-252AA footprint matches the design layout before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 6 A RMS current rating at 600 V blocking voltage is required in a compact surface-mount form factor. Consider the 35 mA gate sensitivity for low-power microprocessor interfaces. Evaluate thermal management requirements based on the TO-252AA package's heat dissipation capabilities relative to the expected duty cycle.

Triacs Part Context

This part belongs to the Littelfuse Alternistor series, which utilizes a symmetrical structure for high dv/dt immunity. The Q6006DH4RP is a specific variant within the Qxx08xHx family line, distinguished by its 6 A current rating and specific surface-mount packaging configuration compared to through-hole alternatives.

Triacs Replacement Considerations

Direct pin-compatible replacements may include other 6 A, 600 V TRIACs in TO-252 packages from Littelfuse or competitors, provided gate trigger currents and holding currents match the circuit design constraints.
