The CDZ9.1B is a Zener diode manufactured by Rohm Semiconductor. Zener diodes are designed to maintain a constant voltage across them when the voltage applied exceeds the Zener voltage. This makes them useful for voltage regulation, voltage reference, surge suppression, and clipping applications. Due to its End-of-Life status, direct replacements may be difficult to source.

Applications

• Voltage Regulation: Used in power supplies to provide a stable output voltage.
• Voltage Reference: Provides a known voltage for comparison in circuits.
• Surge Suppression: Protects sensitive components from voltage spikes.
• Clipping Circuits: Limits the voltage of a signal to a specific level.

Features

• Zener Voltage: 9.1V (This is the voltage at which the diode starts to conduct in the reverse direction and maintain a constant voltage).
• Low Leakage Current: Minimizes power loss and improves efficiency.
• Small Package Size: Allows for compact circuit designs.
• High Reliability: Ensures consistent performance over time.

Benefits

• Stable Voltage Output: Provides a consistent voltage for sensitive circuits.
• Protection from Voltage Spikes: Prevents damage to downstream components.
• Simple Circuit Design: Easy to integrate into existing circuits.
• Cost-Effective Solution: Offers a reliable and affordable voltage regulation option.
