Q6012LH5

Triacs Overview

The Littelfuse Q6012LH5TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 12 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 1.3 V, and a gate trigger current of 50 mA. The on-state voltage is specified at 1.6 V, with a maximum off-state leakage current of 10 µA at VDRM. Non-repetitive peak on-state currents are rated at 100 A and 120 A under different pulse conditions. The component utilizes a TO-220-2 through-hole package.

Triacs Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant specifications. Confirm RoHS compliance status and specific lead times directly with authorized distributors or the manufacturer before placing orders. Ensure the procurement documentation matches the required technical parameters for your specific application design.

Triacs Selection Notes

Select this component based on its 600 V blocking voltage and 12 A continuous current rating. Verify that the gate drive circuit can supply the required 50 mA trigger current. Consider the TO-220-2 package for adequate heat dissipation in through-hole PCB layouts. Ensure the operating environment stays within the specified -40°C to +125°C temperature range for optimal reliability.

Triacs Part Context

This part belongs to the Littelfuse Qxx12xHx series of high-temperature triacs. These devices are engineered for robust performance in demanding AC power switching scenarios. The series emphasizes snubberless operation and high dv/dt immunity, making them suitable for direct replacement in various industrial and consumer AC control designs requiring reliable thyristor-based switching.

Triacs Replacement Considerations

Direct replacements may include other 600 V, 12 A triacs in TO-220 packages from Littelfuse or competitors, provided they match the gate trigger characteristics and thermal ratings. Verify pinout compatibility and ensure the substitute device meets the same snubberless and high dv/dt requirements for equivalent circuit performance.
