BC80825MTF

Overview

The BC80825MTF is a PNP epitaxial silicon transistor housed in an SOT-23 package. It features a collector-emitter voltage of -25 V and a continuous collector current of -800 mA. The device provides a minimum DC current gain (hFE) of 160 at a collector current of -100 mA, with a maximum value of 400. Thermal characteristics include a power dissipation rating of 310 mW and a junction-to-ambient thermal resistance of 403 °C/W.

Feature Summary

• Designed for switching and amplifier applications
• Suitable for AF-driver stages and low-power output stages
• Functions as the complement to the BC817/BC818 NPN transistor series

Applications

• Switching circuits
• Amplifier applications
• AF-driver stages
• Low power output stages

Procurement Notes

Verify the specific ordering suffix against ON Semiconductor's official database to ensure compatibility with system requirements. Confirm that the component meets RoHS standards and lead-free specifications. Check for any Fairchild integration updates regarding part nomenclature changes from underscores to dashes. Validate compliance with commercial certification status before procurement.

Selection Notes

Select this component when a PNP small-signal transistor with a -25 V collector-emitter breakdown voltage is required. Ensure the application demands a continuous collector current capability up to -800 mA. Verify that the SOT-23 surface-mount package fits the board layout constraints. Consider the hFE classification range of 160 to 400 for circuit biasing stability.

Part Context

This device belongs to the BC807/BC808 family of PNP epitaxial silicon transistors originally developed by Fairchild Semiconductor and now managed by ON Semiconductor. The '25' designation indicates the -25 V collector-emitter voltage rating, distinguishing it from the -40 V rated BC808-40 variant. It serves as the complementary counterpart to the BC817/BC818 NPN series.

Replacement Considerations

The BC808-40 offers a higher voltage rating of -40 V but shares similar current capabilities. The BC807-25MTF provides a higher voltage rating of -45 V. Verify pinout compatibility and thermal resistance values when substituting these variants.
