QK010LH5TP

Triacs Overview

The QK010LH5TP is a snubberless alternistor triac rated for 1 kV off-state voltage and 10 A on-state current. It utilizes an ITO-220AB package with an isolated tab for through-hole mounting. The device features gate trigger currents of 50 mA across all quadrants (I_GT: 50-50-50 mA). Key electrical parameters include a maximum on-state voltage of 1.6 V and an off-state leakage current of 10 µA at V_DRM.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC networks in AC switching applications
• High thermal stability supports operation up to +150°C junction temperature
• Isolated tab construction facilitates efficient heat dissipation and electrical isolation

Triacs Applications

• Motor speed control systems
• Temperature modulation circuits
• AC phase control loads

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS3 compliance status as indicated in distributor listings. Ensure ordering suffixes match the required package type and lead time requirements, which are typically around 12 weeks from manufacture.

Triacs Selection Notes

Select this component for high-voltage AC applications requiring robust snubberless performance. The 1 kV rating suits industrial environments with significant line noise. The TO-220AB package allows for effective thermal management using standard heatsinking techniques suitable for medium-power solid-state switching tasks.

Triacs Part Context

This part belongs to the Littelfuse Q Series, designed for low-power TRIAC applications up to 1200V. The series offers bi-directional solid-state switching capabilities specifically engineered for AC switching and phase control. It provides reliable performance in household and industrial equipment requiring precise power modulation.
