Additional Details

The UMZ27N's key specifications include the Zener voltage (VZ), Zener test current (IZT), reverse leakage current (IR), and power dissipation (PD). The Zener voltage is the voltage at which the diode starts to conduct in the reverse direction. The Zener test current is the current at which the Zener voltage is measured. The reverse leakage current is the current that flows through the diode in the reverse direction when the voltage is below the Zener voltage. Consult the Rohm Semiconductor datasheet for detailed electrical characteristics, thermal specifications, and package dimensions. Proper handling precautions should be taken to avoid damage from electrostatic discharge (ESD).
