5.1 Volt, 1 Watt Zener Diode – Precision Voltage Regulation

Reliable 5.1V Zener Diode for Power Regulation

This 5.1V, 1W Zener diode is engineered for stable and accurate voltage regulation across a variety of electronic circuits. Designed for applications requiring precise voltage reference or overvoltage protection, this through-hole component delivers consistent performance in demanding environments.

Key Technical Specifications

• Nominal Zener (Regulating) Voltage: 5.1 Volts
• Power Dissipation: 1 Watt (through-hole mount)
• Package Type: DO-41 Axial Lead
• Vetco Part Numbers: VET135A, WW135A, 1N4733 (Old NTE Part Number: NTE135A)
• Package Quantity: 1 piece per package

Applications

• Voltage regulation in power supplies and DC-DC converters
• Overvoltage protection for sensitive circuits
• Reference voltage source for analog and digital systems

Usage Instructions

To use, connect the Zener diode in reverse bias across the load or circuit where precise voltage clamping is required. Ensure that the power dissipation does not exceed 1W for reliable, long-term operation.
