Description and Introduction

Zener TVSs The SMBJ11CA is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 11V  
- **Voltage - Breakdown (VBR):** 12.2V (Min), 13.5V (Typ), 14.8V (Max)  
- **Voltage - Clamping (VC):** 19.9V at 1A  
- **Current - Peak Pulse (IPP):** 1A (8/20µs)  
- **Power - Peak Pulse (PPP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  
- **Polarity:** Bidirectional (CA suffix)  

### **Description:**  
The SMBJ11CA is a bidirectional TVS diode designed to protect sensitive electronics from voltage transients, such as ESD, lightning, and inductive switching events. It provides fast response times and high surge capability.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Withstands transient events up to 600W.  
- **Bidirectional Protection:** Guards against both positive and negative voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  

This information is based solely on the manufacturer's datasheet for the SMBJ11CA by Microsemi.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB11CA --: Same SMB (DO-214AA) package, 600W bidirectional TVS with 11V standoff voltage, direct functional equivalent from a major TVS supplier.
  • 1SMB11CA --: SMB-packaged 600W bidirectional transient voltage suppressor with matching 11V working voltage, widely available and pin-compatible.
  • SMAJ11CA --: Bidirectional TVS with the same 11V standoff voltage in the smaller SMA package; usable where slightly lower 400W surge rating and reduced footprint are acceptable.
  • P6SMB12CA --: Same SMB package bidirectional TVS with a close standoff voltage (12V vs 11V) and comparable clamping, widely available from a major TVS supplier.
  • 1SMB12CAT3G --: Bidirectional 600W SMB TVS diode with 12V standoff, directly interchangeable in most surge protection designs and from a well-established manufacturer.
  • SMAJ12CA --: Bidirectional TVS in SMA package with 12V standoff; slightly lower power rating (400W) but a good drop-in for space-constrained or lower-surge applications.
