Description and Introduction

Zener TVSs The SMBJ8.5CA is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 8.5V  
- **Voltage - Breakdown (V_BR):** 9.45V (Min)  
- **Voltage - Clamping (V_C):** 13.9V at 10A (Typ)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AA (SMB)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Bidirectional  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Provides ESD protection for circuits up to 8.5V.  
- Bidirectional TVS diode, meaning it clamps both positive and negative voltage spikes.  
- RoHS compliant and halogen-free.  

### **Features:**  
- Low clamping voltage for effective transient suppression.  
- Fast response time (typically <1ps).  
- High surge capability (400W peak pulse power).  
- Surface-mount package for automated assembly.  
- Meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) standards.  

This information is based on Vishay's official datasheet for the SMBJ8.5CA. For detailed performance curves and test conditions, refer to the manufacturer's documentation.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB10CA --: Bidirectional TVS diode in the P6SMB series with comparable 600W peak pulse power and a standoff voltage close to the SMBJ8.5CA, suitable as a drop-in SMB replacement.
  • 1SMB10CAT3G --: Bidirectional 600W SMB TVS diode with similar clamping characteristics and a different series naming, making it an easy-to-distinguish alternative.
  • SMAJ8.5CA --: Bidirectional TVS diode with the same 8.5V standoff voltage in the SMAJ series; lower power rating but electrically compatible for many clamping applications.
