Zener Diode (3.6V) 0.5W 5pcs

The Zener Diode (3.6V) 0.5W pack contains five through-hole zener diodes with a 3.6 V zener voltage and a 0.5 W power rating. Connected in reverse with a series resistor, a zener holds the voltage across it at about 3.6 V, which makes it a simple way to create a reference voltage, protect 3.3 V microcontroller inputs from overvoltage, or build a basic low-current regulator.

Zener Diode (3.6V) 0.5W Specifications

• Zener voltage: 3.6 V (nominal)
• Power rating: 0.5 W
• Type: zener diode, axial leads, through-hole
• Polarity: the band marks the cathode
• Pack size: 5 pieces

Zener Diode (3.6V) 0.5W Applications

• Clamping signals to protect 3.3 V inputs on ESP32, ESP8266 and Raspberry Pi
• 3.6 V reference voltage for comparators and ADC inputs
• Simple shunt regulators for low-current circuits
• Level limiting in sensor and interface circuits
• Electronics classes and lab experiments

What's in the Box

• 5 × 3.6 V 0.5 W zener diodes

Tip: Connect the cathode (band) to the positive side and always use a series resistor: R = (Vin − 3.6 V) / I. For example, from 12 V at 10 mA use about 820 Ω, which keeps the zener at around 0.04 W, far below its 0.5 W rating.
