BC327A

Single Bipolar Transistors Overview

The onsemi BC327A is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. It features a maximum collector current of 800 mA and a collector-emitter breakdown voltage of 45 V. The device operates within a junction temperature range of -55°C to 150°C and dissipates up to 625 mW of power. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 100 mA, a transition frequency of 260 MHz, and a collector cutoff current of 100 nA. It utilizes a TO-92 (TO-226AA) through-hole package.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact hFE binning and packaging variations. Confirm RoHS compliance status and current lifecycle stage via authorized distributors. Ensure the ordering part number matches the required gain group and physical package dimensions specified in the datasheet.

Single Bipolar Transistors Selection Notes

Select this component when a standard PNP BJT with moderate current handling and high-frequency response is required. Consider the 45V breakdown limit and 800mA current capacity relative to circuit demands. Evaluate the TO-92 package constraints for thermal management and board space requirements compared to surface-mount alternatives.
