2SA1619ARA

Single Bipolar Transistors Overview

The Panasonic 2SA1619ARA is a silicon PNP epitaxial planar transistor designed for low-frequency power and driver amplification. It operates in a TO-92NL-A1 package with radial taping for automatic insertion. The device supports a collector current of 0.5 A and peak current of 1 A, with a collector power dissipation of 1 W at 25°C. The 2SA1619A variant provides a collector-emitter voltage rating of -50 V, while the standard 2SA1619 is rated at -25 V. Both share a collector-base voltage limit of -30 V (standard) or -60 V (A variant). Transition frequency reaches 200 MHz.
