QK010L5

Triacs Overview

The Littelfuse QK010L5 is a logic level triac designed for high-voltage AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an RMS on-state current (IT(RMS)) of 10 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220AB 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 of 50 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 10 µA at VDRM.

Triacs Feature Summary

• Logic level sensitivity enables direct drive from standard logic circuits with low gate trigger requirements.
• High voltage blocking capability supports robust performance in demanding AC power control environments.
• Thermal stability ensures reliable operation across extended industrial temperature ranges.

Triacs Applications
