FKPF12N80

Triacs Overview

The FKPF12N80 is a Bi-Directional Triode Thyristor manufactured by Fairchild Semiconductor, now part of onsemi. It features an 800V repetitive peak off-state voltage and a 12A RMS on-state current capability in a TO-220F package. Key electrical characteristics include a gate trigger voltage maximum of 1.5V across all quadrants and a holding current limit of 50mA. The device supports a critical rate of rise of on-state current (di/dt) of 50 A/µs and offers a junction-to-case thermal resistance of 3.0 °C/W. It operates within a junction temperature range of -40°C to 125°C.

Triacs Feature Summary

• Planar silicon construction designed for high reliability and robust switching performance.
• Bidirectional triode thyristor architecture enabling control in both AC current directions.
• High surge on-state current capacity supporting transient load conditions.

Triacs Applications

• Switching mode power supplies
• Light dimmers and electric flasher units

Triacs Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm the specific revision status of the datasheet, as legacy components may have updated documentation or obsolescence notices. Ensure the TO-220F package dimensions match the required PCB footprint constraints for the intended assembly process.

Triacs Selection Notes

Select this component for applications requiring 800V blocking capability with moderate current handling up to 12A RMS. Consider the thermal management requirements based on the 3.0 °C/W junction-to-case resistance when designing heat sinks. Evaluate the gate trigger characteristics against the driving circuit's available voltage and current levels to ensure reliable turn-on across all operating quadrants.

Triacs Part Context

This device belongs to the family of planar silicon triacs developed by Fairchild Semiconductor. It is commonly utilized in consumer electronics and industrial control circuits where bidirectional AC power switching is necessary. The TO-220F package provides a cost-effective solution for through-hole mounting in medium-power applications.
