QK010NH5RP

Triacs Overview

The Littelfuse QK010NH5RP is a bidirectional triac belonging to the Qxx10xx series, designed for surface-mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 10 A. The device supports non-repetitive on-state currents of 100 A or 120 A depending on the specific test condition. Key electrical parameters include a maximum holding current (Ih) of 50 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 50 mA. The on-state voltage is specified at 1.6 V with a leakage current of 10 uA at VDRM. It operates within a temperature range of -40 C to +125 C.

Triacs Feature Summary

• High thermal stability and robust construction suitable for demanding power control environments
• Sensitive gate drive capability allowing for efficient triggering with low power control signals
• Surface-mount design facilitates automated assembly and compact circuit board layouts

Triacs Applications

• Solid-state relays requiring high switching reliability
• AC motor speed control circuits for industrial equipment
• Lighting dimmer modules for commercial and residential applications

Triacs Procurement Notes

Verify the specific suffix configuration against the official Littelfuse datasheet to ensure compatibility with required packaging and voltage ratings. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into regulated supply chains. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 10 A continuous current capacity are required in a surface-mount form factor. Ensure the gate drive circuit can provide at least 1.3 V and 50 mA to guarantee reliable turn-on. Consider the thermal management requirements associated with the SMTO-263-2 package for the intended operating environment.

Triacs Part Context

This triac is part of the Qxx10xx family from Littelfuse, which standardizes pinouts and mechanical dimensions across various voltage ratings. This allows designers to swap between different voltage variants, such as 600 V or 800 V versions, without altering the PCB layout, simplifying the development process for multi-voltage product lines.

Triacs Replacement Considerations

Compatible substitutes within the same series include QK010N5RP and QK010NH5TP. Verify that the alternative part matches the 400 V rating and SMD package requirements before substitution.
