QJ8008L5TP

Triacs Overview

The Littelfuse QJ8008L5TP is a bidirectional triac designed for high-power AC switching applications. It features an RMS on-state current rating of 8 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. Non-repetitive peak on-state currents are specified at 83 A and 100 A under different conditions, with an on-state voltage of 1.6 V and a leakage current of 50 uA.

Triacs Feature Summary

• Bidirectional conduction capability for AC power control
• High thermal stability operating up to 125°C
• Robust 800 V blocking voltage rating

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the exact part number against official Littelfuse documentation, as the QJ8008L5TP designation may represent a specific variant or internal code distinct from standard commercial listings. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before procurement planning.

Triacs Selection Notes

Select this component when an 800 V bidirectional switch is required for moderate power AC loads. Ensure the gate drive circuit can supply the necessary 50-75 mA trigger current. Verify that the TO-220-2 package provides adequate thermal management for the expected RMS current in the specific application environment.

Triacs Part Context

This component belongs to the Qxx08xx series of thyristors manufactured by Littelfuse. The series is characterized by robust construction suitable for industrial environments. The QJ8008L5TP specifically denotes an 8 Ampere, 800 Volt device within this family, sharing common design principles with other members regarding thermal performance and triggering characteristics.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers for the QJ8008L5TP were not identified in available documentation. Engineers should consult Littelfuse technical support or cross-reference databases for equivalent 8A/800V TO-220-2 triacs if direct substitution is required.
