Description and Introduction

Zener TVSs The SMBJ20CA is a bidirectional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronics from voltage transients and surges. Below are the specifications, descriptions, and features based on the manufacturer LF (Littelfuse):

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 20V  
- **Voltage - Breakdown (V_BR):** 22.2V (Min), 24.7V (Typ), 27.4V (Max)  
- **Voltage - Clamping (V_C):** 32.4V @ 1A  
- **Peak Pulse Current (I_PP):** 24.2A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 600W (10/1000μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  

### **Descriptions:**  
- **Type:** Bidirectional TVS Diode  
- **Application:** Surge protection for low-voltage circuits  
- **Mounting Type:** Surface Mount  
- **RoHS Compliant:** Yes  

### **Features:**  
- **Low Clamping Voltage:** Provides effective transient protection.  
- **High Surge Capability:** Handles high transient currents.  
- **Bidirectional Operation:** Protects against both positive and negative transients.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Reliable Performance:** Robust construction for industrial applications.  

This information is sourced from the manufacturer Littelfuse (LF) datasheet for the SMBJ20CA TVS diode.

Alternative Part Number

  • P6SMB20CA --: Same 600W bidirectional TVS in SMB package with 20V standoff, direct functional equivalent from a major supplier.
  • 1SMB20CAT3G --: 600W bidirectional SMB TVS diode with 20V working voltage, widely available and electrically compatible.
  • SMAJ20CA --: 400W bidirectional TVS with 20V standoff in SMA package; lower power rating but usable in less demanding clamping applications.
  • 1SMB20CA --: SMB-package bidirectional TVS with matching 20V standoff and clamping characteristics, suitable drop-in replacement.
