Q2N3RP

Triacs Overview

The Q2N3RP is a logic-sensitive gate TRIAC manufactured by Littelfuse Inc., designed for surface-mount applications in the DO-214 (Compak) package. It features an off-state voltage rating of 200V and an RMS on-state current of 1A. The device supports non-repetitive surge currents of 16.7A at 50Hz and 20A at 60Hz. Key electrical parameters include a maximum gate triggering current of 10mA, ensuring compatibility with low-power control circuits.

Triacs Feature Summary

• Logic-sensitive gate architecture for efficient triggering
• Surface-mount design for automated assembly
• Compact Compak package for space-constrained PCBs

Triacs Applications

• Lighting control systems
• Small motor speed regulation
• Heating element control circuits

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging configuration, such as tape and reel or bulk quantities, as this affects handling procedures. Ensure the component matches the required voltage and current ratings for the target application. Cross-reference the datasheet for thermal management requirements during installation.

Triacs Selection Notes

Select this component when a compact surface-mount TRIAC with low gate drive requirements is necessary. The 200V rating suits low-voltage AC applications. Consider the 1A current limit for small loads. The logic-sensitive gate simplifies interface with microcontrollers or standard logic ICs without additional driver circuitry.

Triacs Part Context

This part belongs to the Littelfuse TRIAC family, specifically optimized for sensitive gate operation. It is distinct from high-power industrial TRIACs due to its lower current rating and surface-mount form factor. The DO-214 package provides a balance between thermal performance and board space efficiency for consumer electronics.

Triacs Replacement Considerations

Equivalent parts include other 200V, 1A logic-sensitive TRIACs in SMD packages. Verify pinout compatibility and thermal characteristics before substitution. Check manufacturer datasheets for direct cross-reference recommendations.
