5V6 1W Zener Diode – Precision Voltage Regulation ⚡

The 5V6 1W Zener Diode is engineered for stable, precise voltage regulation in DC circuits. Once in reverse breakdown, it maintains a nearly constant voltage, making it ideal as a reference voltage, for clamping, and for overvoltage protection across a broad range of electronics components and modules. Suited for both electronics engineers and hobbyists, it integrates seamlessly with Arduino, Raspberry Pi, and other microcontroller-based projects.

✅ Key Features

• Nominal Zener Voltage: 5.6 V (5V6) for dependable regulation
• 1 W power dissipation for robust performance in low-to-moderate power designs
• DO-41 through-hole package for easy breadboarding and soldering
• Reliable reference voltage and voltage clamp function
• Ideal for Arduino/Raspberry Pi interfacing, sensor protection, and microcontroller ADC references

🔧 Specifications

• Power Dissipation: 1 Watt
• Zener Voltage (this model): 5.6 V nominal (5V6)
• Zener Voltage (family options): Varies by model (e.g., 3.3 V, 5.1 V, 12 V, 24 V, etc.)
• Maximum Zener Current: Typically 20–100 mA (dependent on voltage rating)
• Package Type: DO-41 (axial, through-hole)

📌 Applications

• Voltage regulation and stabilization in DC power rails
• Reference voltage source for analog circuits and ADCs
• Overvoltage protection and transient clamping for I/O lines
• General-purpose electronics and hobby projects

🤖 Use with Arduino, Raspberry Pi, and Microcontrollers

Protect GPIOs, create simple shunt regulators, or provide a reference for ADC measurements. Always use a series resistor to set Zener current and limit power:

• Resistor selection: R ≈ (Vin − VZ) / IZ
• Power check: PZ = VZ × IZ ≤ 1 W
• Example: From 12 V to 5.6 V at ~20 mA → R ≈ (12 − 5.6) / 0.02 ≈ 320 Ω (use standard 330 Ω)

🧰 Design Notes

• Current and temperature affect the exact Zener voltage; test at the intended operating current
• Ensure adequate thermal management to keep dissipation within the 1 W limit
• Observe polarity: the banded lead is the cathode (connect to the more positive node in reverse-bias use)

A dependable, cost-effective choice for engineers, students, and makers who need a rugged voltage regulation solution in their electronics projects.
