Additional Details

The VDZ24B typically comes in a small surface-mount package like SOD-323. Key electrical parameters include a Zener voltage (Vz) around 24V, a low reverse leakage current (Ir), and a power dissipation rating dependent on the package type. Detailed specifications, such as the Zener test current (Izt) and temperature coefficients, can be found in the manufacturer's datasheet. The diode is designed for operation within a specified temperature range, often from -55°C to +150°C. The forward voltage drop is usually around 0.9V to 1.1V at a forward current of 10mA. Dynamic impedance is another important parameter, indicating the change in Zener voltage with respect to the change in Zener current; lower impedance indicates better voltage regulation.
