PIN CONFIGURATION
DESCRIPTION
Silicon N-channel enhancement
mode vertical D-MOS transistor
designed for communications
transmitter applications in the UHF
frequency range.
The transistor is encapsulated in a
4-lead, SOT172D studless package,
with a ceramic cap. All leads are
isolated from the mounting base.
