BFG590,215

Overview

The BFG590,215 is an NPN silicon planar epitaxial transistor designed for wideband RF applications up to 5 GHz. It features a maximum transition frequency of 5 GHz and a maximum unilateral power gain of 13 dB at 900 MHz. The device operates with a collector-emitter voltage of 15 V and supports a DC collector current of 200 mA. Total power dissipation reaches 400 mW when the soldering point temperature is maintained at or below 60 °C. The component utilizes gold metallization for reliability and is housed in a 4-lead SOT143B plastic surface-mounted package.
