QK010N5RP

Triacs Overview

The Littelfuse QK010N5RP is a bidirectional triac from the Qxx10xx series, rated for 10 A RMS on-state current and 1 kV repetitive peak off-state voltage. It operates within a junction temperature range of -40°C to +125°C and features a maximum holding current of 50 mA. The device exhibits a typical on-state voltage of 1.6 V and a gate trigger voltage of 2.5 V, with non-repetitive peak on-state currents specified at 100 A and 120 A. Packaged in an SMTO-263-2 surface-mount format, it supports Reel, Cut Tape, and MouseReel configurations.

Triacs Feature Summary

• Four-quadrant logic level triggering capability for reliable gate control across all polarity combinations.
• Surface-mount construction in an SMTO-263-2 package designed for automated PCB assembly processes.
• High thermal stability supporting operation up to +125°C junction temperature.

Triacs Applications

• Solid-state relay switching circuits
• AC motor speed control systems
• Lighting dimmer applications

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number QK010N5RP against official Littelfuse documentation. Confirm that the received units match the specified SMTO-263-2 package and electrical ratings. Ensure compliance with RoHS and REACH standards as indicated in the product specifications before integration into production lines.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 1 kV blocking voltage are required in a surface-mount form factor. The 50 mA holding current and 2.5 V gate trigger voltage define the drive requirements. Compare against other Qxx10xx variants if different voltage or current ratings better suit the specific circuit design constraints.

Triacs Part Context

This triac belongs to the Qxx10xx family, which provides standardized high-voltage thyristor solutions. The suffix 'N' indicates the surface-mount SMTO-263-2 package, while '5RP' denotes the specific gate sensitivity class and reel packaging configuration within the Littelfuse product lineup.

Triacs Replacement Considerations

QK010N5TP serves as a pin-compatible alternative using a tube package instead of reel/cut tape. Other QK010xx variants may offer different voltage ratings but require verification of package and electrical parameter compatibility.
