QJ8010NH4TP

Triacs Overview

The Littelfuse QJ8010NH4TP is a high-temperature Alternistor TRIAC rated for 10 A RMS on-state current and 800 V repetitive peak off-state voltage. Housed in a TO-263 (D2PAK) surface-mount package, it operates within a junction temperature range of -40°C to +150°C. The device features a maximum gate trigger current of 35 mA across Quadrants I, II, and III, with a typical holding current of 40 mA. It supports non-repetitive surge currents up to 120 A at 60 Hz and includes glass-passivated junctions for parameter stability.

Triacs Feature Summary

• Alternistor design enables reliable switching in Quadrants I, II, and III without requiring an external snubber network
• High thermal capability allows operation up to 150°C junction temperature for improved heat dissipation
• Glass-passivated junctions ensure long-term reliability and stable electrical parameters
• Solid-state construction eliminates arcing and contact bounce associated with mechanical switches

Triacs Applications

• AC solid-state switching and phase control circuits
• Heater control systems and lighting dimmers
• Motor speed controls for power tools and lawn care equipment
• White goods and brown goods appliance motor drives

Triacs Procurement Notes

Verify the specific suffix 'H4' corresponds to the required 35 mA gate trigger sensitivity for your circuit design. Confirm that the TO-263 package footprint matches your PCB layout requirements. Ensure the 800 V rating provides adequate margin for your line voltage transients. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Triacs Selection Notes

Select this component when high commutation performance is needed for extremely inductive loads. The Alternistor topology simplifies design by removing snubber components. Compare the 35 mA gate drive requirement against your controller's output capabilities. Consider the TO-263 package for surface-mount assembly efficiency compared to through-hole alternatives.

Triacs Part Context

This part belongs to the QJxx10xHx series of 10 A high-temperature Alternistors from Littelfuse. The series offers multiple voltage ratings and package options including TO-220 isolated, TO-220 non-isolated, and TO-263. The 'N' designation indicates the TO-263 surface-mount package, while 'H4' specifies the 35 mA gate sensitivity level for three-quadrant operation.

Triacs Replacement Considerations

QJ8010NH3TP: Identical electrical characteristics except for lower gate trigger current (10 mA). QJ8010NH5TP: Identical electrical characteristics except for higher gate trigger current (50 mA). QJ8010R4TP: Same electrical specs but in a TO-220 through-hole package.
