BFS20 Description

Short technical summary and product information.

The BFS20 is an NPN silicon epitaxial planar transistor designed for general purpose signal processing, switching, and amplification applications. It is manufactured by Diotec Semiconductor and comes in a compact SOT-23-3 surface mount package.

 

Key electrical characteristics include a maximum collector-emitter voltage of 20V, collector-base voltage of 30V, and emitter-base voltage of 4V. The continuous collector current is rated at 25mA, with a power dissipation of 200mW. DC current gain (hFE) ranges from 40 to 140 at VCE=10V, IC=7mA. The transistor offers a gain-bandwidth product of 450MHz, making it suitable for high-frequency applications up to VHF.

 

The device is housed in a TO-236-3 / SC-59 / SOT-23-3 package with a UL 94V-0 case material. It is supplied in tape and reel packaging with 3000 units per 7-inch reel. The operating junction temperature range is -55°C to 150°C, with a thermal resistance of less than 625 K/W junction-to-ambient.

 

The BFS20 is RoHS3 compliant and REACH unaffected, with MSL level 1 (unlimited). It is suitable for commercial and industrial grade applications, and variants with AEC-Q101 compliance are available (suffix -Q or -AQ).
