QJ8006LH4TP

Triacs Overview

The Littelfuse QJ8006LH4TP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current (It rms) of 6 A and a rated repetitive peak off-state voltage (Vdrm) of 800 V. The device has a non-repetitive peak on-state current capability of 80 A or 85 A, depending on the specific pulse width conditions defined in the datasheet. The maximum on-state voltage is 1.6 V, while the holding current (Ih) maximum is 35 mA. Gate trigger voltage (Vgt) is specified at 1.3 V with a gate trigger current (Igt) of 35 mA. The component operates within a temperature range starting from -40°C and utilizes a TO-220-2 package for through-hole mounting.

Triacs Feature Summary

• High-voltage blocking capability suitable for mains-connected loads
• Sensitive gate drive requirements allowing direct microprocessor interfacing
• Robust thermal management via exposed tab package design

Triacs Applications

• Solid-state relays for residential and commercial heating controls
• Lighting dimmer circuits for incandescent and LED loads
• Motor speed control systems for small appliances

Triacs Procurement Notes

Verify the exact suffix 'QJ' against official Littelfuse documentation to confirm it denotes a specific tape-and-reel variant or packaging option distinct from standard tube packaging. Confirm RoHS compliance status directly from the manufacturer's latest declaration. Ensure the ordering quantity aligns with the distributor's minimum order requirements and lead times prior to finalizing procurement plans.

Triacs Selection Notes

Select this component when an 800 V blocking voltage is required for AC switching applications. The 6 A continuous current rating suits moderate-power loads. Verify that the gate trigger characteristics match the driving circuit's output capabilities. Consider the thermal resistance of the TO-220-2 package and ensure adequate heatsinking if operating near the maximum current limit under continuous duty cycles.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xxH series of high-voltage triacs. The series is engineered for general-purpose AC power switching. The 'QJ' prefix likely indicates a specific manufacturing lot, packaging configuration, or regional compliance variation within the broader Q8006 product family. It shares core electrical specifications with other variants in the 6 A, 800 V class.

Triacs Replacement Considerations

Direct replacements include the Q8006LH4TP and other 6 A, 800 V triacs in TO-220 packages from Littelfuse or compatible manufacturers such as STMicroelectronics or Vishay. Verify pinout compatibility and thermal performance before substitution.
