Philips Semiconductors Product specification
PNP 4 GHz wideband transistor BFT92W
FEATURES
• High power gain
• Gold metallization ensures
excellent reliability
• SOT323 (S-mini) package.
APPLICATION
It is intended as a general purpose
transistor for wideband applications
up to 2 GHz.
DESCRIPTION
Silicon PNP transistor in a plastic,
SOT323 (S-mini) package. The
BFT92W uses the same crystal as the
SOT23 version, BFT92.
