Description and Introduction

BI The part **SM8LZ47** is manufactured by **TOSHIBA**. Below are the specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Manufacturer:** TOSHIBA  
- **Part Number:** SM8LZ47  
- **Type:** Zener Diode  
- **Voltage (Vz):** 47V (Zener Voltage)  
- **Power Dissipation (Pd):** 500mW  
- **Tolerance:** ±5%  
- **Package:** SOD-323 (Small Outline Diode)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
- The SM8LZ47 is a **surface-mount Zener diode** designed for voltage regulation and protection in electronic circuits.  
- It provides a stable **47V reference voltage** when operated in the reverse breakdown region.  
- Suitable for **low-power applications** due to its **500mW power rating**.  

### **Features:**  
- **High reliability** with stable Zener voltage characteristics.  
- **Compact SOD-323 package** for space-constrained PCB designs.  
- **Low leakage current** in forward and reverse bias conditions.  
- **RoHS compliant**, ensuring environmental safety.  

For exact performance curves and application notes, refer to the official **TOSHIBA datasheet**.

Application Scenarios & Design Considerations

Alternative Part Number

  • 1N4756A --: 47V 1W zener diode in a DO-41 axial package; a widely available general-purpose replacement for the 47V zener function, though package and mounting differ from the original surface-mount part.
  • BZT52C47 --: 47V surface-mount zener diode in SOD-123, offering a close functional match for the 47V regulation voltage with a compact SMD footprint.
  • MMSZ47T1G --: 47V 500mW surface-mount zener in SOD-123; suitable as a functional substitute where the 47V zener voltage and low-power SMD package are the key requirements.
  • BZV85-C47 --: 47V 1.3W axial zener diode offering comparable voltage tolerance and power handling in a DO-41 package.
  • 1N5261B --: 47V 500mW axial zener diode suitable for lower-power 47V regulation where the original's full power rating is not required.
