19V 1/2W Zener Diode Reliable Voltage Regulation

Precision 19V 0.5W Zener Diode for Electronic Circuits

This 19V 1/2W Zener diode is designed for applications requiring stable and precise voltage regulation. With a nominal regulating voltage of 19.0 volts and a 500mW (0.5W) power dissipation rating, it is an ideal choice for a wide range of voltage reference, protection, and regulation circuit designs.

Key Features

• Nominal Zener Regulating Voltage: 19V
• Power Dissipation: 0.5 Watt
• Style: Through hole
• Package Quantity: 1
• Part Number Reference: NTE5028A

Typical Applications

• Voltage regulation in DC power supplies
• Reference voltage generation
• Protection against overvoltage conditions
• Clipping and clamping circuits

Usage Instructions

For optimal performance, ensure the Zener diode is installed in a circuit where the power dissipation does not exceed 0.5W and the current is limited according to your circuit’s requirements. Install in the correct polarity, with the cathode marking indicating the regulated output voltage reference point in your design.
