Description
The SMV114x series of
silicon
hyperabrupt junction varactor
diodes is specifically designed with an increasing gamma versus
voltage characteristic. This results in improved Voltage-Controlled
Oscillator (VCO) frequency-voltage linearity compared to a
conventional hyperabrupt junction varactor.
The SMV114x family of varactors is characterized for capacitance
and resistance over temperature.
Table 1 describes the various packages and markings of the
SMV114x varactors.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
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 potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. The
SMV114x varactors are Class 0 Human Body Model (HBM) ESD devices.
