Q8012NH2TP

Triacs Overview

The Littelfuse Q8012NH2TP is a high-temperature Alternistor TRIAC rated for 800V repetitive peak off-state voltage and 12A RMS on-state current. It features a TO-263 (D2PAK) surface-mount package designed for robust thermal performance. Key electrical parameters include a maximum gate trigger current of 10 mA, a holding current of 15 mA, and an operating temperature range from -40°C to 150°C. The device supports a critical rate of rise of off-state voltage of 150 V/µs and a commutating dv/dt of 2 V/µs.

Triacs Feature Summary

• High-temperature operation capability up to 150°C junction temperature
• Surface-mount TO-263 package design for automated assembly
• Alternistor technology providing enhanced ruggedness against di/dt stress

Triacs Applications

• Motor speed control systems
• Temperature modulation circuits
• General AC phase control applications

Triacs Procurement Notes

Verify the specific suffix 'TP' corresponds to the required tape-and-reel packaging configuration when sourcing. Confirm that the TO-263 footprint matches the target PCB layout. Ensure the 12A RMS rating aligns with the thermal management capabilities of the final application environment.

Triacs Selection Notes

Select this component for applications requiring surface-mount TRIACs with high thermal resilience. The 10 mA gate sensitivity suits low-power drive circuits. Consider the 800V blocking voltage for standard mains or industrial AC line voltages. Evaluate the TO-263 thermal resistance against the expected power dissipation levels.

Triacs Part Context

This part belongs to the Qxx12xHx series of high-temperature Alternistor TRIACs from Littelfuse. These devices are engineered as solid-state switches for AC switching tasks. The series offers variants in different packages including TO-220AB and isolated versions, but the NH2TP specifically denotes the TO-263 form factor.

Triacs Replacement Considerations

Cross-reference with other 12A, 800V Alternistor TRIACs in TO-263 packages. Verify compatibility regarding gate trigger current limits and holding current specifications before substitution.
