FKPF12N80YDTU

Triacs Overview

The FKPF12N80YDTU is a Bi-Directional Triode Thyristor (Triac) manufactured by onsemi, originally developed by Fairchild Semiconductor. It features an 800 V repetitive peak off-state voltage and supports a continuous RMS on-state current of 12 A at a case temperature of 82°C. The device utilizes a TO-220F package with thermal resistance from junction to case rated at 3.0 °C/W. Key electrical characteristics include a gate trigger voltage maximum of 1.5 V and a holding current limit of 50 mA. The component operates within a junction temperature range of -40°C to 125°C and provides an isolation voltage of 1500 V AC.

Triacs Feature Summary

• Bi-directional conduction capability for AC switching applications
• High surge on-state current handling up to 132 A at 60 Hz
• Robust insulation with 1500 V isolation voltage rating
• Planar silicon construction for reliable thermal performance

Triacs Applications

• Switching mode power supplies
• Light dimmer circuits
• Small motor control systems
• Electric blanket and solenoid drivers

Triacs Procurement Notes

Verify the specific ordering suffix YDTU against official documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status through manufacturer datasheets or compliance statements. Ensure the source document explicitly identifies the part as active or obsolete before procurement planning.

Triacs Selection Notes

Select this component for AC load control requiring 800 V blocking capability and 12 A continuous current. Evaluate thermal management requirements based on the 3.0 °C/W junction-to-case resistance. Consider the 132 A surge rating for inductive loads. Verify gate trigger current compatibility with the driving circuitry across the operating temperature range.

Triacs Part Context

This Triac belongs to the FKPF series, designed for general-purpose AC power switching. Originally released by Fairchild Semiconductor, the product line was integrated into onsemi's portfolio following corporate acquisition. The TO-220F package facilitates through-hole mounting with direct heatsinking capabilities for high-power dissipation scenarios.

Triacs Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement devices match the 800 V voltage rating, 12 A current capacity, and TO-220F package dimensions. Verify equivalent gate trigger characteristics and thermal resistance values.
