105V 10W Zener Diode – Reverse Polarity, Stud Mount

High-Reliability Zener Regulation for Power Applications

The NTE5221AK is a robust, stud-mount Zener diode with a nominal regulating voltage of 105V and a maximum power dissipation rating of 10 watts. Designed for demanding roles in voltage regulation and overvoltage protection, this diode delivers stable performance in power supplies, industrial controls, and test instrumentation.

Technical Specifications

• Zener Voltage (Nominal): 105V
• Power Dissipation: 10W (stud mount for enhanced heat transfer)
• Polarity: Reverse (cathode to stud)
• Package: DO-4 (Chassis/Stud mount)
• Quantity Per Package: 1

Typical Applications

• Precision voltage regulation in power management circuits
• Overvoltage protection for sensitive electronics
• Voltage reference standards in measurement and instrumentation systems
• Industrial and high-reliability circuit designs

Installation and Usage Notes

Mount the NTE5221AK using the threaded stud for secure mechanical connection and optimal thermal performance. Proper heatsinking is recommended to maintain maximum power dissipation and long-term device reliability. Observe correct polarity orientation during installation—reverse polarity configuration (cathode to stud) is required for proper operation.
