2SC4521T-TD-E

Single Bipolar Transistors Overview

The 2SC4521T-TD-E is an NPN epitaxial planar silicon transistor manufactured by onsemi, designed for high-speed switching applications. It features a collector-emitter voltage (VCEO) of 45V and a continuous collector current (IC) of 3A. The device has a maximum power dissipation of 1.5W at 25°C and operates within a junction temperature range of -55°C to +150°C. Packaged in a PCP-4 (PCP T/R) format with three leads and a tab, it utilizes FBET and MBIT processes to achieve high breakdown voltage and large current handling capabilities suitable for electronic circuit switching.
