2SA2127X

Single Bipolar Transistors Overview

The onsemi 2SA2127 is a PNP single bipolar transistor designed for low saturation voltage applications. It features an adoption of the MBIT process, providing high current capacity and wide safe operating area (ASO). The device operates with a collector-to-emitter voltage of -50V and a continuous collector current of -2A. Key electrical characteristics include a DC current gain (hFE) ranging from 200 to 560 at -100mA, and a gain-bandwidth product of 420 MHz. The package is MP (TO-92/SC-51), suitable for through-hole mounting.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official documentation, as packaging quantities vary between bag and box configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant matches the required thermal dissipation and ambient temperature operating conditions specified in the datasheet.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring a PNP switch with low VCE(sat) to minimize power loss. Consider the -50V breakdown voltage and -2A current rating when designing for relay or lamp loads. Evaluate the thermal resistance and junction temperature limits for high-power applications. Verify that the MP package fits the PCB layout constraints.
