QJ8010R5TP

Triacs Overview

The Littelfuse QJ8010R5TP 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-220AB non-isolated (R-Package) through-hole form factor with three terminals: MT1, MT2, and Gate. The device operates within a junction temperature range of -40°C to +150°C and withstands a non-repetitive surge current of 120 A at 60 Hz. It features a maximum gate trigger current of 50 mA in Quadrants I, II, and III, and 75 mA in Quadrant IV.

Triacs Feature Summary

• Standard TRIAC configuration operating primarily in Quadrants I & III when triggered from an AC line.
• Glass-passivated junctions provide protection against environmental degradation.
• Solid-state switching eliminates arcing and contact bounce associated with mechanical relays.
• Restricted RFI generation depending on the sine wave activation point.

Triacs Applications

• AC solid-state switches
• Light dimmers
• Heating control systems
• Motor speed controls

Triacs Procurement Notes

Verify the specific package variant and sensitivity code during acquisition. Confirm that the TO-220AB non-isolated mounting tab aligns with the thermal management strategy. Ensure the ordering suffix matches the required lead form dimensions for the target PCB layout.

Triacs Selection Notes

Select this component for applications requiring standard quadrant triggering without the need for Alternistor functionality across all three quadrants. Evaluate the thermal resistance characteristics to ensure adequate heat sinking for continuous operation near the 10 A rating limit.

Triacs Part Context

This part belongs to the QJxx10xx series of high-temperature TRIACs manufactured by Littelfuse. The series includes variants with different voltage ratings, packages, and gate sensitivities designed for robust AC power control.

Triacs Replacement Considerations

Consult the official datasheet for direct equivalents within the QJxx10xx family. Verify compatibility regarding gate sensitivity thresholds and physical package dimensions before substituting.
