Description and Introduction

Zener TVSs The SMBJ9.0A is a transient voltage suppressor (TVS) diode manufactured by GS (General Semiconductor). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 9.0V  
- **Voltage - Breakdown (V_BR):** 10.0V (min)  
- **Voltage - Clamping (V_C):** 14.5V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**  
- The SMBJ9.0A is a surface-mount TVS diode designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  
- It is part of the SMBJ series, which offers high surge capability in a compact SMB package.  
- It is RoHS compliant and halogen-free.  

### **Features:**  
- Low clamping voltage for effective protection.  
- Fast response time (typically <1ns).  
- High surge current capability.  
- Bi-directional (for certain variants, confirm polarity for unidirectional).  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

For exact polarity (unidirectional or bidirectional) and additional details, refer to the manufacturer's datasheet.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB9.1A --: Same SMB package unidirectional TVS with a 9.1V standoff voltage close to the original, providing comparable clamping and surge protection.
  • 1SMB9.0AT3G --: SMB-packaged unidirectional TVS diode with 9.0V standoff and 600W peak pulse rating, a direct functional match for the SMBJ9.0A.
  • SMAJ9.0A --: Unidirectional 9.0V standoff TVS with similar electrical characteristics; SMA package is smaller but suitable where 400W surge capability is acceptable.
