HSMP-386x
Surface Mount PIN Diodes
Data Sheet
Description/Applications
The HSMP-386x series of general purpose PIN diodes
are designed for two classes of applications. The first
is attenuators where current consumption is the most
important design consideration. The second applica-
tion for this series of diodes is in switches where low
capacitance is the driving issue for the designer.
The HSMP-386x series Total Capacitance (C
T
) and Total
Resistance (R
T
) are typical specifications. For applica-
tions that require guaranteed performance, the general
purpose HSMP-383x series is recommended.
A SPICE model is not available for PIN diodes as
SPICE does not provide for a key PIN diode character-
istic, carrier lifetime.
