Description and Introduction

Zener TVSs The SMBJ90CA is a transient voltage suppressor (TVS) diode manufactured by Microsemi. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 90V  
- **Voltage - Breakdown (V_BR):** 100V (min)  
- **Voltage - Clamping (V_CL):** 146V at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AA (SMB)  
- **Polarity:** Bidirectional (CA suffix)  

### **Description:**  
The SMBJ90CA is a surface-mount TVS diode designed to protect sensitive electronics from high-voltage transients, such as ESD, lightning, and inductive load switching. It provides bidirectional clamping to suppress both positive and negative voltage spikes.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Handles high transient currents.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **RoHS Compliant:** Meets environmental standards.  
- **Surface-Mount Design:** Suitable for automated assembly processes.  

This information is based solely on the manufacturer's datasheet and product documentation.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB100CA --: Bidirectional TVS diode in the P6SMB series with comparable 600W peak pulse power and a close standoff voltage, suitable drop-in replacement for SMBJ90CA.
  • 1KSMB100CA --: Bidirectional 1000W TVS in SMB package offering higher surge capability and similar clamping characteristics, a robust alternative to SMBJ90CA.
  • SMAJ90CA --: Bidirectional TVS with the same 90V standoff voltage in SMA package; lower power rating but electrically compatible for many clamping applications.
  • 1SMB90CAT3G --: Bidirectional 600W SMB TVS diode with the same 90V standoff voltage, offering a direct functional replacement in a similar SMB package.
