BSX20 Description

Short technical summary and product information.

The BSX20 is an NPN switching transistor manufactured by Phihong USA, housed in a TO-18 metal package. It is designed for low current applications, with a maximum collector current of 200 mA, and low voltage applications, with a maximum collector-emitter voltage of 15 V.

This transistor is suitable for high-speed saturated switching and HF amplifier applications. Key electrical characteristics include a DC current gain (hFE) ranging from 40 to 120 at 10 mA and 1 V, a transition frequency (fT) of 500 MHz minimum at 10 mA and 10 V, and a turn-off time of 30 ns maximum.

The BSX20 operates within a wide temperature range, from -65 °C to +150 °C, with a total power dissipation of 360 mW at 25 °C ambient temperature. Its thermal resistance from junction to ambient is 480 K/W.

This component is ideal for designers requiring a reliable NPN switching transistor for fast switching circuits and high-frequency amplification stages where low power and voltage are critical.
