diodes results in resistance of 20 Ωmaximum at 1 mA and
7 Ωmaximum at 10 ble in a selection of plastic
packages:as a single diode in the small footprint
SOD-323 package and in a variety of configurations in the
SOT-23 package, including a low inductance (0.4 nH)
SMP1304-007 available in the SOT-143
package are three diode junctions designed for insertion
in TEE attenuators (SMP1304-018) and PI attenuators
(SMP1304-019).Also available in a SOT-5 (SMP1304-027)
package as a four diode array designed for insertion in the
commonly used 4 diode PI attenuator circuit.

SMP1304-019 PI Attenuator PIN Diodes
The SMP1304-019 employ three PIN diode junctions in
a SOT-143 are configured for ease of

SMP1304-007
In the -007 configuration of the SOT-23 package, the
package inductance is effectively reduced to 0.4 nH, in
comparison to the 1.5 nH value of the standard
lower inductance will be particularly
beneficial when the diodes are used as shunt connected
switches at frequencies higher than 500 MHz, where
inductance is the primary limitation on maximum switch
isolation.
To achieve the effective 0.4 nH, the SOT-23 package must
be inserted in the microstrip circuit board with a gap in the
trace, as shown in the e of the polarity of
the diode junction, this low inductance feature is only
realizable with the cathode connected to ground.
