BCW66F-TP

Overview

The BCW66F-TP is a silicon NPN plastic-encapsulated transistor manufactured by Micro Commercial Components. It operates within a collector-emitter voltage (VCEO) of 45 V and a collector-base voltage (VCBO) of 75 V, with an emitter-base breakdown voltage (VEBO) of 5 V. The device supports a maximum DC collector current of 800 mA and handles a power dissipation of 200 mW. It functions reliably across a temperature range from -55°C to +150°C. Packaged in the SOT-23-3 surface-mount format, it is supplied in reel quantities for automated assembly processes.
