Description/Applications
The HSMP-381x series is

4810
481B
specifically designed for low
distortion attenuator applica-
tions. The HSMP-481x products
feature ultra low parasitic
inductance in the SOT-23 and
SOT-323 packages. They are
specifically designed for use at
frequencies which are much
higher than the upper limit for
conventional diodes.
A SPICE model is not available
for PIN diodes as SPICE does not
provide for a key PIN diode
characteristic, carrier lifetime.
