The UDZV11B is a Zener diode manufactured by Rohm Semiconductor. Zener diodes are used to provide a stable reference voltage or to protect circuits from overvoltage conditions. They operate by maintaining a nearly constant voltage across their terminals when reverse-biased and conducting in the breakdown region.

Applications:

• Voltage Regulation: Used to provide a stable voltage reference in power supplies and other circuits.
• Overvoltage Protection: Protects sensitive components from voltage spikes and surges.
• Clipping Circuits: Used to clip or limit the voltage in a circuit to a desired level.
• Voltage Shifting: Shifts the voltage level of a signal.
• Calibration Circuits: Used in calibration equipment to provide accurate voltage references.

Features:

• Precise Zener Voltage: Provides a stable and accurate Zener voltage.
• Low Reverse Leakage Current: Minimizes current leakage in the reverse direction.
• Small Package Size: Compact package for space-constrained applications.
• High Surge Current Capability: Withstands surge currents in overvoltage protection applications.
• Stable Performance: Offers stable performance over temperature and time.
