QK010N5TP

Triacs Overview

The Littelfuse QK010N5TP is a bidirectional triac designed for high-voltage power control applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an on-state RMS current (It RMS) of 10 A. The device operates within a 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. Non-repetitive peak currents are specified at 100 A and 120 A, with a leakage current of 10 uA under VDRM conditions.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding AC power switching environments
• Surface mount construction in a compact SMTO-263-2 package for automated PCB assembly
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

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

Triacs Procurement Notes

Verify the specific Littelfuse datasheet revision to confirm exact gate trigger current limits and mechanical dimensions before finalizing the design. Ensure the ordering quantity aligns with the manufacturer's standard tube packaging requirements. Cross-reference the RoHS compliance status with current regulatory standards for the target market.

Triacs Selection Notes

Select this component when a 1 kV rating and 10 A continuous current capacity are required in a surface-mount form factor. Compare the 50 mA holding current specification against circuit load requirements to ensure reliable latching. Evaluate the thermal resistance of the SMTO-263-2 package against the expected heat dissipation in the final enclosure design.

Triacs Part Context

This part belongs to the Qxx10xx series of thyristors from Littelfuse. The series provides standardized high-voltage triac solutions for industrial and consumer power control. The QK010N5TP variant specifically targets applications requiring higher gate sensitivity compared to lower-sensitivity counterparts in the same family.

Triacs Replacement Considerations

Direct substitutes may include other 1000V 10A triacs in SMTO-263 packages from Littelfuse or competitors, provided gate trigger parameters match. Verify pinout compatibility and thermal characteristics before substitution.
