The BZM55C9V1 is a Zener diode manufactured by Vishay. It's designed to provide a stable reference voltage of 9.1V for voltage regulation and overvoltage protection applications. The 'C' signifies a tolerance of approximately 5%. Though listed as END-OF-LIFE, this component was previously prevalent in numerous electronic circuits.

Applications:

• Voltage regulation
• Overvoltage protection
• Clipping circuits
• Level shifting
• Reference voltage source

Features:

• Fixed Zener voltage (9.1V)
• Tight voltage tolerance
• Low dynamic impedance
• Small plastic package (typically SOD-80C)
• High reliability

Benefits:

• Provides a stable and precise voltage reference
• Protects circuits from overvoltage conditions
• Simplifies circuit design
• Reduces component count
• Cost-effective solution

Additional Details:

The BZM55C9V1 provides a stable 9.1V reference voltage, which is critical for many electronic circuits requiring precise voltage control. The low dynamic impedance ensures the Zener voltage remains relatively constant over a wide range of operating currents. The small plastic package makes it suitable for space-constrained applications. Though end-of-life, Vishay datasheets will likely provide details on Zener voltage vs. Zener current characteristics, reverse leakage current, and power dissipation capabilities. Designers building new systems should investigate alternative Zener diodes.
