FKN2L60BU

Triacs Overview

The FKN2L60 is a Bi-Directional Triode Thyristor (Triac) manufactured by onsemi, originally designed by Fairchild Semiconductor. It features a TO-92 package with three leads: T1, Gate, and T2. The device supports a repetitive peak off-state voltage of 600 V and an RMS on-state current of 1.5 A at a case temperature of 65°C. Surge on-state current ratings are 9 A at 50 Hz and 10 A at 60 Hz for a single half-cycle. The junction temperature range spans from -40°C to 125°C, with a thermal resistance from junction to case of 40 °C/W.

Triacs Feature Summary

• Bi-directional conduction capability suitable for AC switching applications
• Logic-sensitive gate design allowing low power trigger requirements
• Guard-ring structure integrated for enhanced stress protection

Triacs Applications

• Switching mode power supplies
• Light dimmer circuits
• Electric flasher units
• Small motor control systems

Triacs Procurement Notes

Verify the component status carefully as the source datasheet indicates it may be obsolete or discontinued by Fairchild Semiconductor. Confirm availability through authorized distributors or secondary markets. Ensure the TO-92 package dimensions match the target PCB footprint. Check for RoHS compliance if required by specific manufacturing standards.

Triacs Selection Notes

Select this component for low-power AC load control where a compact TO-92 package is necessary. Ensure the circuit design accommodates the 1.5 A RMS current limit and the 600 V blocking voltage. Consider the thermal resistance of 40 °C/W when calculating heat dissipation in enclosed environments. Verify that the gate trigger current requirements align with the driving logic levels.

Triacs Part Context

This part belongs to the FKN series of triacs produced by Fairchild Semiconductor, now under onsemi. The FKN2L60 specifically targets general-purpose AC switching needs. It shares the TO-92 form factor with other low-current thyristors but offers distinct voltage and current ratings compared to higher-power variants like the FKN3L60.

Triacs Replacement Considerations

Check for direct equivalents such as the MCR100-6 or similar TO-92 triacs with matching 600V/1.5A ratings. Verify pinout compatibility (T1, Gate, T2) before substitution. Ensure replacement parts meet the same thermal and electrical specifications.
