BC807-25B5003

Overview

The BC807-25B5003 is a PNP surface-mount transistor manufactured by Infineon Technologies, utilizing the BC807 series architecture. It features an epitaxial planar die construction housed in a SOT-23 package. The device is characterized by a collector-emitter voltage (VCEO) of -45 V and a continuous collector current (IC) of 0.5 A. Maximum power dissipation is rated at 0.3 W at 25°C ambient temperature. The junction temperature range extends up to 150°C. This component serves as a general-purpose switching and amplification element within electronic circuits.

Feature Summary

• Epitaxial planar die construction for robust performance
• SOT-23 surface-mount packaging suitable for automated assembly
• Complementary NPN type availability

Applications

• General purpose switching applications
• Audio frequency (AF) driver circuits
• Amplifier stages

Procurement Notes

Verify the manufacturer origin carefully, as the BC807-25 designation is widely used by multiple semiconductor vendors including NXP, Diodes Inc., and Taiwan Semiconductor. Confirm that the specific suffix B5003 corresponds to the intended Infineon or authorized distributor reel specification. Ensure the datasheet matches the required electrical parameters for your design constraints.

Selection Notes

Select this component when a low-power PNP transistor with a -45 V rating is required in a compact SOT-23 footprint. Consider the complementary BC817-25 if an NPN counterpart is needed for push-pull configurations. Evaluate thermal management requirements given the 0.3 W power dissipation limit in small packages.

Part Context

This part belongs to the BC807 family of general-purpose PNP transistors. These devices are standard components in discrete semiconductor catalogs, often replacing older silicon AF transistors. The BC807-25 variant specifically denotes a minimum DC current gain (hFE) bin, typically ranging from 160 to 320, ensuring consistent amplification characteristics across production batches.

Replacement Considerations

Direct substitutes include BC807-25 parts from other manufacturers such as NXP Semiconductors, Diodes Incorporated, or Taiwan Semiconductor, provided they share the SOT-23 package and identical electrical ratings.
