Additional Details

The VDZ30B is commonly available in surface-mount packages, such as SOD-323. Important electrical characteristics include a Zener voltage (Vz) of approximately 30V, a low reverse leakage current (Ir), and a power dissipation rating dependent on the package type. Detailed specifications, including the Zener test current (Izt) and temperature coefficients, are available in the manufacturer's datasheet. This diode is designed to operate within a specified temperature range, generally from -55°C to +150°C. The forward voltage drop typically ranges from 0.9V to 1.1V at a forward current of 10mA. Dynamic impedance is a crucial parameter, indicating the change in Zener voltage relative to the change in Zener current; a lower impedance suggests better voltage regulation.
