BC857C TR PBFREE

Overview

The BC857C TR PBFREE is a single PNP small-signal bipolar junction transistor manufactured by Central Semiconductor Corp. It operates with a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. The device features a minimum DC current gain (hFE) of 220, ensuring high amplification capability. It is housed in an SOT-23 surface-mount package and supports a maximum power dissipation of 200 mW. The component functions reliably within a temperature range of -65 °C to +150 °C.

Feature Summary

PNP polarity configuration for general-purpose switching and amplification
High DC current gain with a minimum specification of 220
Compact SOT-23 surface-mount packaging for space-constrained designs
Wide operating temperature range suitable for harsh environments

Applications

General purpose signal amplification circuits
Low-power electronic switching applications
Complementary pairs with NPN transistors like the BC846 series

Procurement Notes

Verify the specific hFE binning grade required for the application, as gain ranges vary across the BC857 family. Confirm RoHS compliance status via the manufacturer's latest documentation, as historical data indicates potential variations in lead-free certification for this part number. Ensure the ordering suffix matches the exact reel or cut-tape requirements specified in the official datasheet.

Selection Notes

Select this component when a PNP transistor with moderate voltage handling and high current gain is needed. The 45 V rating distinguishes it from lower-voltage alternatives, while the 100 mA limit suits low-power tasks. Compare against the BC857A and BC857B variants if different gain thresholds are necessary for the specific circuit design.

Part Context

This part belongs to the widely adopted BC857 series of PNP small-signal transistors. It serves as the complementary counterpart to the BC846 and BC847 NPN devices. The series is standardized across multiple manufacturers for use in portable electronics and general consumer equipment requiring reliable surface-mount switching components.
