BC857BM-TP

Overview

The BC857BM-TP is a dual PNP bipolar junction transistor (BJT) array manufactured by Micro Commercial Components. It is housed in an SOT-363 surface-mount package and features a maximum collector-emitter voltage of 45V and a continuous collector current of 200mA. The device has a power dissipation rating of 300mW, a transition frequency of 200MHz, and a DC current gain of at least 220 at 2mA and 5V. It operates within a temperature range of -55°C to 150°C.

Feature Summary

• Dual PNP configuration integrated into a single compact SOT-363 package for space-efficient circuit design.
• High-speed switching capability supported by a 200MHz transition frequency.
• Robust thermal performance with a maximum junction temperature rating of 150°C.

Applications

• General-purpose signal amplification
• Switching applications in low-power circuits
• Audio pre-amplifier stages

Procurement Notes

Verify the specific suffix against official Micro Commercial Components documentation to confirm pinout compatibility and electrical tolerances. Ensure that the sourcing channel provides valid RoHS compliance certificates and traceability records consistent with the manufacturer's standards for this component series.

Selection Notes

Select this component when a dual PNP configuration is required in a small outline package. Compare the 200mA current rating and 45V breakdown voltage against circuit requirements. Consider the SOT-363 footprint constraints and thermal dissipation limits relative to the application's power budget.

Part Context
