QJ8010L4TP

Triacs Overview

The Littelfuse QJ8010L4TP 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 an electrically isolated TO-220AB (L-package) with a maximum junction temperature of 150°C. The device features a DC gate trigger current of 25 mA across Quadrants I, II, and III, and a gate trigger voltage of 1.3 V maximum. It supports non-repetitive surge currents up to 120 A at 60 Hz and offers a critical rate-of-rise of off-state voltage of 600 V/µs at 800 V.

Triacs Feature Summary

• High temperature capability with a maximum junction temperature of 150°C
• Glass-passivated junctions for enhanced reliability
• Solid-state switching eliminates arcing and contact bounce

Triacs Applications

• AC solid-state switches and phase control applications
• Heating, lighting, and motor speed controls
• Power tools and lawn care equipment
• Home brown goods and white goods appliances

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package isolation and lead form dimensions. Ensure that the selected component meets the required electrical isolation voltage standards for the intended circuit design. Cross-reference the part number with official Littelfuse documentation to validate RoHS compliance and UL recognition status before finalizing procurement specifications.

Triacs Selection Notes

Select this component for AC power control circuits requiring high thermal stability and electrical isolation. The 150°C junction temperature rating allows for robust operation in demanding environments. Verify that the gate drive circuitry can supply the specified 25 mA trigger current. Consider the thermal resistance characteristics when designing heat sinking solutions for continuous 10 A loads.

Triacs Part Context

This part belongs to the QJxx10xx series of 10 A High Temperature Standard TRIACs. The series includes variants with different voltage ratings (600 V or 800 V), packages (TO-220 isolated, TO-220 non-isolated, TO-263), and gate sensitivities. The L-package specifically denotes the electrically isolated TO-220AB configuration.

Triacs Replacement Considerations

Compatible alternatives within the same family include QJ8010R4TP (non-isolated TO-220) and QJ8010N4TP (surface mount TO-263). For electrically isolated requirements, verify if higher sensitivity Alternistor variants like QJ8010LH4TP are suitable for the specific commutation needs.
