68.0 Volt 10 Watt Stud Mount Zener Diode – Reverse Polarity

Reliable 68V Zener Voltage Regulation for Power Applications

The NTE5215AK is a robust Zener diode engineered for precise voltage regulation, featuring a nominal Zener (regulating) voltage of 68.0 volts and a high power dissipation capacity of 10 watts. This stud mount diode is ideally suited for demanding environments where stable voltage reference and protection are critical.

Stud Mount Construction with Reverse Polarity

Designed for secure and efficient installation, this 10W Zener diode utilizes a stud mount (DO-4 package), with a reverse polarity configuration—cathode connected to the stud. This allows for enhanced thermal dissipation and consistent electrical performance for high-reliability circuit designs.

Technical Specifications

• Nominal Zener Voltage: 68.0V
• Power Rating: 10W
• Package: Stud mount (DO-4)
• Polarity: Reverse (cathode to stud)
• Part Number: NTE5215AK
• Quantity Per Package: 1

Engineered for High-Performance Voltage Regulation

This 68 volt Zener diode delivers reliable performance for voltage reference, overvoltage protection, and waveform shaping in power supplies, instrumentation, and industrial automation systems. Stable regulation and robust construction make it an ideal solution for circuits requiring precise voltage control and durable operation under load.

Usage Guidelines

Install using standard stud-mount hardware for optimal heat dissipation and secure electrical connectivity. Ensure proper polarity alignment: cathode must be connected to the stud during mounting. Compatible with a range of electronic and industrial power applications that require reverse polarity zener diodes.
