Key Features and Technical Specifications

• Nominal Zener Voltage: 51.0V (regulating voltage)
• Power Dissipation: 10W
• Package: DO-4 stud mount for enhanced heat dissipation
• Polarity: Cathode to stud (reverse polarity)
• Quantity per package: 1

Applications

• High-reliability power supplies requiring precision voltage reference
• Industrial and commercial voltage regulation circuits
• Surge and overvoltage protection for sensitive electronic equipment
• Clamping and waveform shaping applications

Mounting and Usage Instructions

This 10 watt Zener diode is designed for stud-mounting, enabling secure attachment and efficient thermal transfer in high-power installations. Ensure proper heatsinking when operating at or near maximum ratings. Always observe correct polarity: the cathode is connected to the stud.
