BC80740MTF

Overview

The BC80740MTF is a PNP epitaxial silicon transistor manufactured by ON Semiconductor. It operates with a collector-emitter voltage of -45 V and a continuous DC collector current of -800 mA. The device features a minimum DC current gain (hFE) of 170 at IC = -300 mA, classifying it as the '40' variant within the BC807 series. It is housed in a SOT-23 surface-mount package with a maximum power dissipation of 310 mW and a junction temperature rating up to 150 °C.

Feature Summary

• Designed for general-purpose switching and amplifier applications
• Suitable for AF-driver stages and low-power output stages
• Functions as the complementary counterpart to the BC817 / BC818 NPN transistors

Applications

• General-purpose switching circuits
• Audio frequency driver stages
• Low power output stages

Procurement Notes

Verify the manufacturer source carefully, as this component originated from Fairchild Semiconductor prior to its integration into ON Semiconductor. Confirm that the ordering suffix matches the specific tape and reel packing method required for your assembly line. Ensure the part number does not contain an underscore character, as system updates may have standardized the nomenclature to use a dash instead.

Selection Notes

Select the BC80740MTF when a high-gain PNP transistor is required to complement an NPN circuit using the BC817 series. The '40' designation indicates a specific hFE range suitable for amplification tasks. Verify that the thermal resistance and power dissipation limits align with the PCB land pattern size and ambient operating conditions of the target design.

Part Context

This component belongs to the BC807 family of PNP epitaxial silicon transistors. The '40' suffix denotes the specific DC current gain classification, distinguishing it from lower gain variants like the BC807-16 or BC807-25. The MTF suffix identifies the specific SOT-23 3L tape and reel packaging configuration used for automated surface-mount assembly.
