Q6006LH4TP

Triacs Overview

The Littelfuse Q6006LH4TP is a bidirectional triac in the Qxx06xxH series, designed for general-purpose AC power control. It features a 600 V rated repetitive off-state voltage (VDRM) and conducts an RMS on-state current (IT(RMS)) of 6 A. The device operates within a junction temperature range of -40 °C to +125 °C and utilizes a TO-220-2 through-hole package with an isolated tab. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. Non-repetitive peak on-state currents are specified at 80 A and 85 A, while the on-state voltage is 1.6 V.

Triacs Feature Summary

• Alternistor technology provides high dv/dt immunity without requiring external snubber circuits.
• Isolated mounting tab facilitates heat dissipation and secure installation on heatsinks.
• Robust construction supports operation in demanding industrial and commercial environments.

Triacs Applications

• Solid-state relays
• Lighting dimmers
• Motor speed controllers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal pad configurations. Ensure the procurement channel provides valid traceability records. Confirm that the component meets RoHS compliance requirements as stated in the manufacturer's datasheet before finalizing orders.

Triacs Selection Notes

Select this component when a 600 V blocking capability and 6 A continuous load current are required. The TO-220-2 package is suitable for applications needing robust mechanical mounting and efficient thermal management via an isolated tab. Verify that the gate drive circuit can supply the necessary 35 mA trigger current reliably across the operating temperature range.

Triacs Part Context

This part belongs to the Qxx06xxH family of Alternistor triacs from Littelfuse. These devices integrate high dv/dt protection directly into the silicon structure, distinguishing them from standard triacs that require external RC networks. The family is engineered for reliability in AC switching applications where noise immunity and simplified circuit design are critical priorities.

Triacs Replacement Considerations

Direct replacements must match the 600 V rating, 6 A current capacity, and TO-220-2 package. Verify that substitute components also feature integrated Alternistor technology to maintain equivalent dv/dt performance without additional snubber components.

Triacs FAQ
