Additional Details

The 1SV322's capacitance varies inversely with the applied reverse voltage. The diode's specifications typically include parameters such as the capacitance at a specific reverse voltage, the tuning ratio (the ratio of capacitance at two different reverse voltages), the series resistance, and the reverse leakage current. These parameters are essential for designing and optimizing circuits that utilize the 1SV322. The diode is typically packaged in a small outline package (e.g., SOD-323) for surface mount applications. It is important to consult the datasheet for specific electrical characteristics and recommended operating conditions.
