2N4123-AP

Single Bipolar Transistors Overview

The 2N4123-AP is an NPN silicon general-purpose small-signal transistor manufactured by Micro Commercial Components (MCC). It features a TO-92 molded plastic package with through-hole termination. The device supports a maximum collector-emitter voltage of 30 V and a continuous collector current of 200 mA. Power dissipation reaches 625 mW at 25°C ambient temperature, with a thermal resistance of 200 °C/W junction-to-ambient. Operating and storage temperatures range from -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official MCC documentation to confirm packaging type and compliance status. The AP suffix indicates ammo packing configuration. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability and adherence to handling standards.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring standard NPN switching or amplification within low voltage limits. Evaluate thermal constraints carefully as power dissipation decreases significantly above 25°C ambient temperature. Confirm that the TO-92 package dimensions fit the target PCB layout requirements.

Single Bipolar Transistors Part Context

This part belongs to the 2N4123/2N4124 family of NPN silicon transistors produced by Micro Commercial Components. The datasheet revision D was published on January 1, 2013.
