BCX70H

Overview

The BCX70H is an NPN epitaxial silicon transistor designed for general-purpose applications. It features a collector-emitter voltage (VCEO) of 45 V and a collector-base voltage (VCBO) of 45 V, with an emitter-base voltage (VEBO) rating of 5 V. The device supports a maximum DC collector current of 100 mA and dissipates up to 250 mW of power. Its gain-bandwidth product (fT) reaches 250 MHz, ensuring adequate performance for audio frequency amplification. The component operates within a temperature range of -65°C to +150°C and utilizes the SOT-23-3 surface-mount package.

Feature Summary

NPN epitaxial silicon planar construction optimized for switching and audio frequency amplifier tasks
Suitable for low-level signal processing applications requiring moderate voltage handling capabilities

Applications

General-purpose switching circuits
Audio frequency (AF) amplifier stages
Low-level signal processing applications

Procurement Notes

Verify the specific manufacturer source carefully, as the BCX70H designation appears in documentation from both Fairchild Semiconductor and Nexperia. Confirm whether the required unit is the original Fairchild part or the Nexperia equivalent, as availability and exact specifications may vary between sources. Check datasheet revision dates to ensure compliance with current design requirements.

Selection Notes

Select this component when designing circuits that require an NPN transistor with 45 V voltage ratings and 100 mA current capacity in a compact SOT-23-3 package. Ensure the application does not exceed the 250 mW power dissipation limit. Consider the 250 MHz transition frequency for any high-speed switching needs within the audio frequency range.

Part Context

The BCX70H belongs to the family of small-signal NPN transistors intended for general electronic use. Originally documented by Fairchild Semiconductor, similar devices are now also listed under Nexperia. These transistors serve as fundamental building blocks for analog and digital logic interfaces where moderate gain and voltage isolation are necessary.
