SMV1405-SMV1413: Abrupt Junction Tuning Varactors
Features
High Q Low series resistance for low phase noise G Multiple packages: SOT-23, SC-70 and SC-79 G Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020 G Designed for high-volume commercial applications G SPICE models are available

Absolute Maximum Ratings Description
The SMV1405-SMV1413 series of silicon abrupt junction varactor diodes is designed for use in VCOs requiring tight capacitance tolerances. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The devices are characterized for capacitance over temperature. SPICE models are provided.
Characteristic Reverse voltage (VR) Forward current (IF) Power dissipation (PD) Storage temperature (TST) Operating temperature (TOP) ESD human body model Value 30 V 20 mA 250 mW -55 C to +150 C -55 C to +125 C Class O
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
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, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.
