QK010L5TP

Triacs Overview

The Littelfuse QK010L5TP is a logic level bidirectional triac designed for AC power control 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 junction temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. Leakage current at rated voltage is specified at 10 µA.

Triacs Feature Summary

• Logic level sensitivity enabling direct drive from low-power digital circuits
• High voltage blocking capability suitable for mains-connected loads
• Surface-mount construction for automated PCB assembly

Triacs Applications

• Solid state relay modules
• AC motor speed control circuits
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal pad configuration. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the SMTO-263-2 footprint matches the design intent before finalizing orders.

Triacs Selection Notes

Select this component when high voltage isolation and compact surface-mount packaging are required. Compare the 10 A current rating against peak load requirements. Verify that the logic-level gate drive specifications align with the available control signal voltage levels in the target circuit design.

Triacs Part Context

This part belongs to the Qxx10xx series of thyristors manufactured by Littelfuse. It shares core electrical parameters with other variants in the family but differs in physical package type. The TO-220 variant offers through-hole mounting options, while this model supports SMD processes.

Triacs Replacement Considerations

Direct substitutes include the QK010N5TP for similar performance in alternative packages. Cross-reference with Teccor Electronics equivalents if sourcing flexibility is required. Verify pin compatibility before substituting.
