BC81740NMMTF

Overview

The BC81740NMMTF is an NPN epitaxial silicon transistor manufactured by ON Semiconductor. It operates with a collector-emitter voltage of 45 V and supports a continuous collector current of 800 mA. The device features a DC current gain (hFE) range of 250 to 630 at IC = 100 mA and VCE = 1 V. It has a maximum power dissipation of 310 mW and a transition frequency of 100 MHz. The component is housed in a SOT-23 surface-mount package.

Feature Summary

Suitable for audio driver stages and low power output applications
Provides high current capability within a compact surface-mount footprint
Offers complementary PNP types for push-pull configurations

Applications

General-purpose switching circuits
Audio amplifier driver stages
Low power output stages

Procurement Notes

Verify the manufacturer part number against official ON Semiconductor documentation, as Fairchild order numbers may require suffix adjustments due to system integration. Confirm that the specific ordering suffix matches the required tape and reel packing and matte finish package type before finalizing procurement orders.

Selection Notes

Select this component when a general-purpose NPN transistor with moderate current handling and defined hFE ranges is required. Ensure the application voltage does not exceed the 45 V collector-emitter rating. Consider the thermal resistance characteristics if operating near the maximum power dissipation limit in confined spaces.

Part Context

This device belongs to the BC817 series of NPN epitaxial silicon transistors. It serves as the complementary counterpart to the BC807 series PNP transistors. The product line is designed for general-purpose amplification and switching tasks, offering standardized electrical characteristics across different gain classifications.
