BFS 20 High Frequency Transistor Datasheet
The document describes the BFS 20 surface‑mount transistor packaged in a plastic SOT‑23 (TO‑236) case. It specifies a 3 mm² copper pad for each terminal and details the standard taped‑and‑reeled packaging.
Electrical ratings include a 20 V collector‑emitter voltage, 30 V collector‑base voltage, 4 V emitter‑base voltage, 250 mW maximum power dissipation, and a collector current of 25 mA. Thermal data list a junction temperature of 150 °C, storage range –65 °C to +150 °C, and a junction‑to‑ambient thermal resistance of 420 K/W. Gain, frequency and capacitance parameters are also provided. This manual is written in German.
