The CMPZ5226B is a silicon planar Zener diode from Central Semiconductor Corp. Although designated as END-OF-LIFE, it was previously used for voltage regulation and transient voltage suppression in various electronic circuits. This diode is designed to maintain a stable voltage level when operating in the reverse breakdown region.

Applications

• Voltage regulation in low-power circuits.
• Transient voltage suppression.
• Clipping and clamping circuits.
• Reference voltage sources.

Features

• Silicon Planar Structure: Provides reliable and predictable performance.
• Zener Voltage: Designed to operate at a specific reverse breakdown voltage.
• Low Leakage Current: Minimizes power dissipation.
• Compact Package: Suitable for high-density circuit board designs.

Benefits

• Stable Voltage Regulation: Maintains a consistent voltage output under varying load conditions.
• Protection Against Voltage Spikes: Prevents damage to sensitive components from transient voltages.
• Simple Circuit Integration: Easy to implement in various electronic designs.
• Reliable Performance: Ensures consistent operation over a wide range of operating conditions.

Specifications

While specific specifications may vary, typical parameters include:

• Zener Voltage (Vz): The reverse voltage at which the diode starts to conduct significantly, maintaining a stable voltage.
• Reverse Leakage Current (Ir): The small current that flows when the diode is reverse biased below the Zener voltage.
• Power Dissipation (Pd): The maximum power the diode can dissipate without damage.
• Operating Temperature Range: The range of ambient temperatures in which the diode can operate safely.

Note: As the CMPZ5226B is an END-OF-LIFE product, designers should consider alternative components for new designs.
