Q4010NH5TP

Triacs Overview

The Littelfuse Q4010NH5TP is a bidirectional triac designed for power control applications. It features an RMS on-state current (It RMS) of 10 A and a rated repetitive peak off-state voltage (VDRM) of 400 V. The device has a maximum non-repetitive peak on-state current of 120 A and a maximum on-state voltage of 1.6 V. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 1.3 V and a maximum gate trigger current (Igt) of 50 mA. The holding current (Ih) is limited to a maximum of 50 mA, with an off-state leakage current of 10 uA at VDRM. Operating temperatures range from -40 C to +125 C. It utilizes an SMTO-263-2 surface mount package.

Triacs Feature Summary

• High thermal stability supporting operation up to +125 C
• Robust surge handling capability with 120 A non-repetitive peak current
• Low gate sensitivity for efficient drive circuit design

Triacs Applications

• AC motor speed control circuits
• Solid state relay switching
• Lighting dimmer controls

Triacs Procurement Notes

Verify the specific suffix 'H5TP' against the manufacturer's official datasheet to confirm the exact packaging configuration and compliance status. Ensure that the ordering information matches the required SMTO-263-2 package type and temperature rating specifications before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 10 A RMS current capacity and 400 V blocking voltage are required in a surface-mount form factor. Compare the 1.6 V on-state voltage drop against alternative packages to ensure thermal management meets system constraints. Verify that the 50 mA gate trigger current aligns with the available driver output capabilities.

Triacs Part Context

This part belongs to the Littelfuse Qxx10xx series of high-power triacs. It shares core electrical characteristics with other variants in the family but differs in package style and specific manufacturing revisions. The SMTO-263-2 package provides a compact solution for PCB-mounted power switching compared to traditional through-hole options.

Triacs Replacement Considerations

Direct substitutes within the same series include the Q4012NH5TP, which offers a higher 12 A RMS current rating while maintaining identical voltage and package specifications. Cross-package replacements require careful evaluation of thermal resistance and pinout compatibility.
