QJ8010NH5RP

Triacs Overview

The Littelfuse QJ8010NH5RP is a high-temperature Alternistor TRIAC rated for 10 A RMS on-state current and 800 V repetitive peak off-state voltage. It operates in Quadrants I, II, and III with a maximum junction temperature of 150°C. The device features a TO-263 (D2PAK) surface-mount package with a thermal resistance from junction to case of 1.2 K/W. Gate trigger current ranges up to 50 mA, while the holding current reaches 50 mA. Non-repetitive surge peak on-state current is 120 A at 60 Hz.

Triacs Feature Summary

• Alternistor operation across Quadrants I, II, and III eliminates the need for external snubber networks in highly inductive load applications.
• Electrically isolated semiconductor design recognized under UL 1557 standards.
• Glass-passivated junctions ensure long-term parameter stability and reliability.
• Solid-state switching mechanism prevents arcing and contact bounce associated with mechanical relays.

Triacs Applications

• AC solid-state switches and static switching relays
• Heater control and lighting controls
• Motor speed control systems
• Power tools and lawn care equipment

Triacs Procurement Notes

Verify the specific suffix 'N' confirms the TO-263 D2PAK surface-mount package configuration. Confirm the 'H5' designation aligns with the required 50 mA gate trigger sensitivity for the intended circuit interface. Ensure compliance with RoHS directives if environmental regulations apply to the assembly process.

Triacs Selection Notes

Select this component when high commutation performance is required for inductive loads without snubber circuits. The TO-263 package facilitates efficient heat sinking compared to through-hole alternatives. Verify that the 800 V rating accommodates line voltage transients and that the 10 A RMS rating meets continuous load requirements.

Triacs Part Context

This part belongs to the QJxx10xHx series of 10 A high-temperature Alternistors. It shares the same electrical characteristics as the QJ8010RH5TP but utilizes a different surface-mount package. The series is designed for AC power control applications requiring robust surge handling and high junction temperature tolerance.

Triacs Replacement Considerations

QJ8010RH5TP offers identical electrical specifications in a TO-220 through-hole package. QJ8010LH5TP provides an electrically isolated version in a TO-220 package. Substitution requires verifying package footprint compatibility and mounting torque specifications.
