QJ8010N5RP

Triacs Overview

The Littelfuse QJ8010N5RP 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 N-package (TO-263AB) surface-mount construction with a maximum junction temperature of 150°C. The device features a gate trigger current of 50 mA in Quadrants I, II, and III, and 75 mA in Quadrant IV. Electrical characteristics include a peak on-state voltage of 1.6 V at 14.1 A, a holding current maximum of 50 mA, and a non-repetitive surge current capability of 100 A at 50 Hz or 120 A at 60 Hz.

Triacs Feature Summary

• Standard TRIAC operation restricted to Quadrants I, II, III, and IV triggering.
• Glass-passivated junctions provide protection against corrosion and environmental stress.
• Solid-state switching eliminates arcing and contact bounce associated with mechanical relays.
• Restricted radio frequency interference generation depending on the sine wave activation point.

Triacs Applications

• AC solid-state switches and static switching relays.
• Heating control systems and lighting controls.
• Motor speed control circuits.
• Home appliances and power tools.

Triacs Procurement Notes

Verify the specific suffix 'RP' indicates embossed carrier reel packaging containing 500 units per reel. Confirm that the component matches the TO-263AB physical dimensions and pinout configuration required for the target PCB layout. Ensure the design accommodates the specified thermal resistance values for adequate heat dissipation during continuous operation.

Triacs Selection Notes

Select this part when an 800 V blocking voltage and 10 A RMS current capacity are required in a surface-mount form factor. The 50 mA gate sensitivity suits applications needing moderate drive currents. Verify that the application does not require Alternistor functionality across all three quadrants without snubber networks, as this is a standard TRIAC variant.

Triacs Part Context

This component belongs to the QJxx10xx series of high-temperature thyristors manufactured by Littelfuse. The series includes both Alternistor and Standard TRIAC variants available in TO-220 and TO-263 packages. The QJ8010N5RP specifically denotes the 800 V rating, 10 A current, N-package, and Quadrant IV gate sensitivity within this family.

Triacs Replacement Considerations

QJ8010N5TP serves as a tube-packaged alternative within the same electrical specifications. Other members of the QJxx10xx series may be considered if different voltage ratings or package types are acceptable for the design.
