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 attenu-
ators where current consumption is the most important
design consideration. The second application 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 Re-
sistance (R
T
) are typical specifications. For applications 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 characteristic, carrier
lifetime.
