FCX495TA

Single Bipolar Transistors Overview

The FCX495TA is an NPN high-voltage silicon planar transistor manufactured by Diodes Incorporated. It operates in a SOT-89 surface-mount package with a collector-emitter breakdown voltage (BVCEO) exceeding 150V and supports a continuous collector current of 1A. The device features a low saturation voltage of less than 300mV at 0.5A, ensuring efficient power switching performance. Electrical characteristics include a collector-base breakdown voltage of 170V, a transitional frequency of 100MHz, and a maximum power dissipation of 1W. It functions within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TA' corresponds to the 1,000-unit reel packaging configuration as documented in the manufacturer's ordering information. Confirm that the component status remains Active and matches the required tape width and carrier specifications for automated assembly processes. Ensure compliance with the stated moisture sensitivity level and solderability standards during procurement planning.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high voltage handling up to 150V combined with substantial continuous current capacity of 1A. The low saturation voltage makes it suitable for applications prioritizing minimal conduction losses. Consider the thermal resistance values and derating curves to ensure adequate heat dissipation within the specified operating temperature range for reliable long-term operation.

Single Bipolar Transistors Part Context

This part belongs to the FCX495 series of NPN high-voltage transistors produced by Diodes Incorporated. The series includes variants such as FCX495TC and FCX495Q, which differ primarily in packaging quantities or automotive qualification status. The FCX495TA specifically denotes the standard commercial grade version packaged in reels of 1,000 units.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies FCX495TC as a direct alternative with identical electrical characteristics but different reel packaging quantities. Designers should verify pinout compatibility and thermal performance equivalence before substituting.
