BC857BU3T106

Overview

The BC857BU3T106 is a PNP general-purpose small-signal transistor manufactured by Rohm Semiconductor. It operates with a collector-emitter voltage of 45V and a continuous collector current of 100mA, dissipating up to 200mW of power. The device features a DC current gain (hFE) ranging from 200 to 450. Designed for surface-mount applications, it utilizes the UMT3 package, equivalent to SOT-323 or SC-70, with dimensions of 2.1x2.0mm. It complies with AEC-Q101 automotive standards and supports operating temperatures between -55°C and +150°C.

Feature Summary

Complies with AEC-Q101 automotive reliability standards
High DC current gain range of 200 to 450
Complementary pairing available with BC847BU3HZG

Applications

Automotive-grade low-frequency amplification
General-purpose signal switching
Small-signal processing in vehicle electronics

Procurement Notes

Verify the specific suffix T106 against official Rohm documentation to confirm tape-and-reel packaging specifications. Ensure the component meets AEC-Q101 requirements for your target application. Cross-reference datasheets for exact thermal resistance values and hFE binning codes. Confirm RoHS compliance status directly from the manufacturer's latest release notes before finalizing procurement orders.

Selection Notes

Select this component when an automotive-qualified PNP transistor is required for space-constrained designs. The UMT3 package offers a compact footprint suitable for high-density PCB layouts. Consider the complementary BC847BU3HZG for matched NPN/PNP pairs in differential or push-pull configurations. Verify that the 45V rating aligns with your circuit's maximum voltage swings.
