2SA2223A

Single Bipolar Transistors Overview

The 2SA2223A is a silicon PNP epitaxial planar transistor manufactured by Sanken Electric. It features a collector-emitter voltage (VCEO) of −260 V and a continuous collector current (IC) rating of −15 A at 25 °C case temperature. The device provides a maximum power dissipation (PC) of 160 W and a transition frequency (fT) of 35 MHz. It includes constant hFE characteristics across a wide current range, with ranks defined as R (40-80), O (50-100), and Y (70-140).

Single Bipolar Transistors Procurement Notes

Verify component authenticity through official Sanken channels or authorized distributors. Confirm the specific hFE rank suffix (R, O, or Y) required for your circuit design. Ensure thermal management meets the specified junction-to-case resistance limits. Check for compliance with local environmental regulations regarding lead-free components.

Single Bipolar Transistors Selection Notes

Select this component for high-voltage audio amplification applications requiring robust power handling. Consider the complementary 2SC6145A for push-pull configurations. Evaluate thermal requirements carefully, as the 160 W rating assumes a 25 °C case temperature. Verify that the TO3P-3L package fits the mechanical constraints of the target enclosure.
