DATA SHEET
SMV1129 and SMV1139: Hyperabrupt Junction Tuning Varactors
Features
High Q Low series resistance for low phase noise Available in SOD-323 and SC-79 Designed for high-volume commercial applications SPICE models are available Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020

Absolute Maximum Ratings
Characteristic Forward current (IF) Power dissipation (PD) Storage temperature (TST) Operating temperature (TOP) ESD human body model Value 20 mA 250 mW -55 C to +150 C -55 C to +125 C Class O
Description
The SMV1129 and SMV1139 silicon hyperabrupt junction varactor diodes are designed for use in VCOs requiring low resistance. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.
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.
SMV1139-011 Marking: CG SMV1139-011LF Marking: HG LS = 1.5 nH LS = 0.7 nH
LF denotes lead (Pb)-free, RoHS-compliant packaging option as an alternative to our standard tin/lead (Sn/Pb) packaging.
