8.2V 50W Stud Mount Zener Diode Reverse Polarity

High Power Zener Voltage Regulation for Demanding Applications

This high-reliability 8.2V 50W stud mount Zener diode offers precise voltage regulation in high-current and high-power environments. Engineered for reverse polarity operation (cathode to stud/case), this diode is ideal for power supplies, industrial control systems, and telecommunications equipment where robust voltage control and protection are required.

Technical Specifications

• Zener Voltage (Nominal Regulating Voltage): 8.2V
• Power Dissipation: 50 Watts
• Package Style: DO-5 (DO-203AB) stud mount
• Polarity: Reverse (cathode to case/stud)
• Quantity per Package: 1
• Part Number: NTE5249AK

Usage and Installation

Install the stud mount Zener diode using proper torque to ensure optimal thermal transfer and electrical contact. Reverse polarity configuration requires connection of the cathode to the stud/case, with the anode isolated. Always confirm circuit compatibility with polarity and maximum power ratings.

Applications

• Precision voltage regulation in power supply circuits
• Over-voltage protection for sensitive electronic components
• Industrial and commercial power management systems
• Telecommunications and instrumentation equipment
