BFT25A
NPN 5 GHz wideband transistor
Rev. 04 — 6 July 2004
Product data sheet
1. Product profile
1.1 General description
The BFT25A is a silicon NPN transistor, primarily intended for use in RF low power
amplifiers, such as pocket telephones and paging systems with signal frequencies up
to 2 GHz.
The transistor is encapsulated in a 3-pin plastic SOT23 envelope.
1.2 Features
■ Low current consumption (100 µA to 1 mA)
■ Low noise figure
■ Gold metallization ensures excellent reliability.
