QK015L5

Triacs Overview

The Littelfuse QK015L5 is a Triac component belonging to the Teccor Qxx15xx series, designed for high-voltage AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an on-state RMS current (IT(RMS)) of 15 A. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 100 A or 200 A depending on the specific variant configuration.

Triacs Feature Summary

• High voltage blocking capability suitable for industrial AC control circuits
• Robust thermal performance supporting operation up to 125°C junction temperature
• Sensitive gate drive requirements facilitating direct interface with logic controllers

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify the exact suffix designation when ordering, as Littelfuse utilizes specific codes to denote package variations and manufacturing revisions. Confirm RoHS compliance status through the official datasheet prior to integration. Ensure the selected variant matches the required thermal management specifications for the target enclosure environment.

Triacs Selection Notes

Select this component based on the 1 kV voltage rating and 15 A continuous current requirement. Evaluate the gate trigger sensitivity against the driving circuit's output capabilities. Consider the thermal resistance characteristics if operating near the maximum junction temperature limit in enclosed spaces.

Triacs Part Context

This Triac is part of the broader Teccor family of thyristors manufactured by Littelfuse. The Qxx15xx series designation indicates a standardized platform for 15 A devices. Similar parts in the lineup may offer different voltage ratings or package styles while maintaining comparable current handling capabilities for modular design approaches.

Triacs Replacement Considerations

Cross-reference with other 15 A, 1000 V Triacs from Littelfuse such as the QK015R5 or QK015N5TP. Verify pinout compatibility and thermal pad configurations before substituting to ensure mechanical fit and electrical equivalence.
