QJ8010N4TP

Triacs Overview

The Littelfuse QJ8010N4TP is a standard TRIAC from the QJxx10xx series, rated for 800 V repetitive peak off-state voltage and 10 A RMS on-state current. It utilizes a TO-263 (D²PAK) surface-mount package with a maximum junction temperature of 150°C. The device features a gate trigger current of 25 mA in Quadrants I, II, and III, and 50 mA in Quadrant IV. It supports non-repetitive surge currents up to 120 A at 60 Hz and offers critical rate-of-rise of off-state voltage ratings between 600 and 1000 V/µs depending on voltage class.

Triacs Feature Summary

• Standard TRIAC operation restricted to Quadrants I, II, III, and IV triggering
• Glass-passivated junctions for enhanced reliability
• Electrically isolated semiconductor device recognized under UL 1557
• Restricted RFI generation during switching events

Triacs Applications

• AC solid-state switches and phase control circuits
• Lighting controls and light dimmers
• Heater control systems
• Motor speed control applications

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and sensitivity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with Littelfuse documentation to validate the exact electrical characteristics before finalizing procurement specifications.

Triacs Selection Notes

Select this component for AC power control designs requiring surface-mount integration. The TO-263 package facilitates heat sinking through the mounting tab. Verify that the gate drive circuit can supply the required 25 mA trigger current. Ensure the application voltage does not exceed the 800 V rating and consider thermal management for continuous 10 A operation.

Triacs Part Context

This part belongs to the QJxx10xx series of high-temperature TRIACs manufactured by Littelfuse. The series includes Alternistor variants capable of three-quadrant operation and standard TRIACs. The QJ8010N4TP specifically denotes an 800 V, 10 A standard TRIAC in a TO-263 package with defined gate sensitivities.

Triacs Replacement Considerations

Direct replacements within the same series include QJ8010R4TP (TO-220 non-isolated) or QJ8010L4TP (TO-220 isolated). Verify pinout compatibility and thermal resistance differences when substituting packages.
