9.1V 50W Zener Diode – Reverse Polarity, Stud Mount

High-Power 9.1 Volt 50W Zener Diode for Voltage Regulation

This 9.1V 50W Zener diode is designed for reliable voltage regulation and overvoltage protection in demanding electronic circuits. With its robust stud mount DO-5 package and reverse polarity (cathode to stud), it is ideal for applications requiring stable performance under high power loads.

Key Features and Technical Data

• Nominal Regulating Voltage: 9.1 Volts
• Maximum Power Dissipation: 50 Watts
• Stud Mount DO-5 Package for secure, rugged installation and efficient heat dissipation
• Reverse Polarity: Cathode to stud/case configuration
• QTY Per Package: 1
• Part Number: NTE5251AK

Usage and Applications

This high-power Zener diode is ideally suited for use in power supplies, overvoltage protection circuits, industrial equipment, and custom voltage regulation solutions. Its stud mount design is optimal for securely attaching to heat sinks, allowing for reliable operation even in high-temperature and high-power environments.

Installation Notes

• Mount the stud base to a suitable heat sink for best heat dissipation performance.
• Observe reverse polarity: connect the cathode to the stud/case.
• Verify voltage and power requirements to ensure compatibility with your application.
