HF/VHF power MOS transistor
BLF177
FEATURES
• High power gain
• Low intermodulation distortion
• Easy power control
• Good thermal stability
• Withstands full load mismatch.
PIN CONFIGURATION
DESCRIPTION
Silicon N-channel enhancement
mode vertical D-MOS transistor
designed for industrial and military
applications in the HF/VHF frequency
range.
The transistor is encapsulated in a
4-lead, SOT121 flange envelope, with
a ceramic cap. All leads are isolated
from the flange.
A marking code, showing gate-source
voltage (Vcs) information is provided
for matched pair applications. Refer
to the 'General' section for further
information.
