Description and Introduction

ARK Electronics - SILICON PLANAR ZENER DIODES The part **ZMM20** is a Zener diode manufactured by **DIODE**. Below are the specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Type:** Zener Diode  
- **Voltage (Vz):** 20V (nominal Zener voltage)  
- **Power Dissipation (P):** Typically 500mW  
- **Tolerance:** ±5%  
- **Forward Voltage (Vf):** ~1.2V  
- **Maximum Reverse Leakage Current (Ir):** Typically 5µA  
- **Operating Temperature Range:** -65°C to +150°C  
- **Package:** DO-35 (Glass Axial Lead Package)  

### **Descriptions:**  
- The **ZMM20** is a general-purpose Zener diode designed for voltage regulation and protection in electronic circuits.  
- It maintains a stable voltage (20V) when operated in the reverse breakdown region.  
- Suitable for low-power applications such as voltage reference, clamping, and surge suppression.  

### **Features:**  
- **Precise Voltage Regulation:** Maintains a stable 20V output under specified current conditions.  
- **Low Leakage Current:** Ensures minimal power loss in standby mode.  
- **Compact Package:** DO-35 package allows easy PCB mounting and space-saving designs.  
- **Wide Temperature Range:** Reliable performance across industrial and consumer applications.  

This information is based on standard ZMM series Zener diode specifications from DIODE. For exact details, refer to the official datasheet.

Application Scenarios & Design Considerations

Alternative Part Number

  • BZT52C20 --: 20V zener diode in SOD-123 package, same voltage rating and similar power class as ZMM20, widely available and pin-compatible.
  • MMSZ5250B --: 20V surface-mount zener in SOD-123, matches the 20V regulation value and is a common drop-in replacement for ZMM-series parts.
  • 1N4747A --: 20V 1W zener diode in DO-41 axial package, electrically equivalent voltage rating and suitable when through-hole mounting is acceptable.
