Description and Introduction

Surface mount Silicon-Zener Diodes (non-planar technology) The part **Z1SMA4.7** is manufactured by **DIOTEC**. Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Zener Diode  
- **Voltage (Vz):** 4.7V  
- **Power Dissipation (Pd):** 1W  
- **Package:** SMA (DO-214AC)  
- **Tolerance:** ±5%  
- **Operating Temperature Range:** -65°C to +175°C  
- **Forward Voltage (Vf):** 1.2V (typical at 200mA)  
- **Reverse Leakage Current (Ir):** 5µA (max at 1V)  
- **Zener Impedance (Zz):** 10Ω (typical at Izt)  

### **Descriptions:**
- The **Z1SMA4.7** is a **1W surface-mount Zener diode** designed for voltage regulation and protection in electronic circuits.  
- It provides a stable **4.7V reference voltage** when operated in the reverse breakdown region.  
- The **SMA package** makes it suitable for automated PCB assembly.  

### **Features:**
- **High reliability** with low leakage current.  
- **Precise voltage regulation** for circuit protection.  
- **Compact and robust** SMA package for space-constrained applications.  
- **RoHS compliant** (lead-free).  

This information is strictly factual and derived from Ic-phoenix technical data files. Let me know if you need further details.

Application Scenarios & Design Considerations

Surface mount Silicon-Zener Diodes (non-planar technology)

Alternative Part Number

  • SMAJ4.7A --: Same SMA package unidirectional TVS diode with 4.7V standoff, widely available and electrically similar.
  • P4SMA4.7A --: SMA-packaged 400W TVS diode with matching 4.7V standoff voltage, direct functional replacement.
  • SMA4.7A --: SMA TVS diode with 4.7V working voltage, same form factor and clamping behavior for transient protection.
  • SMAJ5.0A --: SMA TVS diode with 5.0V standoff, close enough to 4.7V for most protection designs and readily stocked as an alternative.
