Additional Details

The VDZ5.6B typically comes in a small surface-mount package such as SOD-323. Key electrical parameters include a Zener voltage (Vz) of about 5.6V, a low reverse leakage current (Ir), and a power dissipation rating that varies depending on the package type. Specific operating conditions, like the Zener test current (Izt) and temperature coefficients, are detailed in the manufacturer's datasheet. It is designed to operate within a specified temperature range, generally from -55°C to +150°C. The forward voltage drop is usually around 0.9V to 1.1V at a forward current of 10mA. The dynamic impedance is an important characteristic, indicating the change in Zener voltage relative to the change in Zener current; a lower value signifies better voltage regulation. Always refer to Rohm Semiconductor’s official datasheet for the most accurate and detailed specifications and application guidelines.
