22.0V 10W Stud Mount Zener Diode Reverse Polarity

Reliable 22V, 10-Watt Stud Mount Zener Diode

This 22.0V, 10W Zener diode (Part Number: NTE5197AK) is designed for robust voltage regulation and overvoltage protection in demanding power supply and circuit protection applications. Engineered for reliability, this component is optimized for industrial, commercial, and high-power electronic systems requiring a stable reference or clamping voltage.

Key Technical Specifications

• Nominal Regulating Voltage (Vz): 22.0 Volts
• Power Dissipation (Ptot): 10 Watts
• Polarity: Reverse (anode to case)
• Package: Stud Mount (DO-4 / DO-203AA)
• Mounting: Chassis/Heatsink via stud for maximum heat dissipation and mechanical durability
• Quantity Per Package: 1

High-Power Zener Regulation and Protection

The stud-mount design ensures superior thermal management and rugged installation suited for high-power environments. With a nominal Zener voltage of 22V and a 10W power rating, this Zener diode is ideal for regulating supply rails, protecting downstream circuitry, and serving as a stable voltage reference across varied temperature ranges.

Typical Applications

• Power Supplies and Industrial Controls
• Voltage Regulation Systems
• Overvoltage Protection in Motor Drives and Inverters
• Reference Voltage Circuits in Test and Measurement Equipment

Usage and Installation

For optimal performance and heat dissipation, mount the Zener diode directly to a metal chassis or suitable heatsink using the integrated stud. Ensure proper polarity: the case acts as the anode, with the cathode identified on the terminal post. This configuration supports efficient clamping and long-term reliability in high-current environments.
