BC857S-13P

Overview

The BC857S-13P is a dual PNP small-signal bipolar junction transistor manufactured by Micro Commercial Components. It integrates two independent PNP transistors within a single SOT-363 surface-mount package. The device supports a maximum continuous collector current of 200 mA and operates with a collector-emitter voltage rating of 45 V. Key electrical characteristics include a DC current gain (hFE) ranging from 125 to 630, a transition frequency of 200 MHz, and a power dissipation capacity of 300 mW. The component functions reliably across an operating temperature range of -55°C to +150°C.

Feature Summary

• Dual configuration integrating two PNP transistors in a compact SOT-363 package for space-efficient circuit design.
• High current handling capability with a maximum collector current of 200 mA suitable for signal switching applications.
• Wide thermal operating range extending up to +150°C for robust performance in demanding environments.

Applications

• General-purpose signal switching and amplification circuits
• Low-power digital logic interface stages
• Audio pre-amplifier input stages

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure that the procurement source provides valid traceability data and confirms RoHS compliance status prior to integration into production schedules.

Selection Notes

Select this component when a dual PNP configuration is required in a minimal footprint. Compare the 200 mA current limit and 45 V voltage rating against circuit requirements. Verify that the SOT-363 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the BC857S series of dual PNP transistors produced by Micro Commercial Components. It serves as a compact alternative to discrete single transistors, reducing board space while maintaining standard small-signal performance metrics defined by the series specifications.

Replacement Considerations

Cross-reference with other manufacturers' dual PNP transistors in SOT-363 packages. Verify that substitute parts match the 200 mA current rating, 45 V voltage limits, and pinout configuration before implementation.
