50 Watt 33.0V Stud Mount Zener Diode (Reverse Polarity)

High-Power Zener Voltage Regulation 33.0V Nominal, Stud Mount

The NTE5269AK is a rugged 50 watt, 33.0 volt stud mount Zener diode engineered for high-reliability voltage regulation and transient suppression in demanding electronic applications. With reverse polarity configuration, this diode is ideal for use in industrial power supplies, voltage reference circuits, crowbar protection, and motor drive controls requiring stable, high-power voltage regulation.

Technical Specifications

• Nominal Zener Voltage: 33.0V
• Power Dissipation: 50 Watts
• Mounting Style: Stud Mount
• Polarity: Reverse
• Package Quantity: 1

Application Notes and Usage

This 33.0V 50W zener diode is commonly specified for use as a stable voltage reference, peak voltage limiter, or surge protection element in circuits exposed to large voltage transients. Its stud mount package provides efficient thermal dissipation, supporting operation in high ambient temperatures or under sustained load.

For optimal performance, ensure proper heat sinking of the stud during installation to maintain power handling capabilities and stable Zener voltage regulation. Reverse polarity orientation allows integration where specific current flow direction and protection schemes are required.

Key Features

• Reliable 33.0V nominal zener voltage for precision regulation
• 50 watt power handling with stud mount package for enhanced heat dissipation
• Reverse polarity design ideal for specialized power management solutions
• Suitable for use in industrial, laboratory, and demanding commercial electronics
