Description
The SMP1321 series of plastic packaged, surface mountable PIN
diodes are designed for high volume switch applications from
10 MHz to beyond 2 GHz. The low capacitance of these diodes
(0.25 pF) combined with its low resistance (2.0
Ω
maximum at
10 mA) make the SMP1321 series particularly suited to high
isolation series connected PIN diode switches in battery operated
circuits. Available in a selection of plastic packages and in a
variety of configurations including a low inductance (0.4 nH)
SOT-23 (SMP1321-007), the small footprint SC-79 and the minia-
ture SC-70. The SMP1321-508 has been specifically designed for
WLAN 802.11 a, b, and g applications.

Skyworks offers lead (Pb)-free “environmentally
friendly” packaging that is RoHS compliant
(European Parliament for the Restriction of
Hazardous Substances).
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION:
Although this device is designed to be as robust as
possible, Electrostatic Discharge (ESD) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
