2SD17050P

Single Bipolar Transistors Overview

The Panasonic 2SD1705 is a silicon NPN epitaxial planar power transistor designed for switching applications. It features a maximum collector current of 10 A and peak current of 20 A, with a collector-emitter voltage rating of 80 V. The device dissipates up to 70 W at 25°C case temperature and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a low collector-emitter saturation voltage (VCE(sat)) of 1.5 V max at 10 A and a transition frequency (fT) of 20 MHz. It utilizes the TOP-3F-A1 package.
