Description and Introduction

Zener TVSs The SMBJ40A is a transient voltage suppressor (TVS) diode manufactured by CONCORD. Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V₃₀):** 40V  
- **Voltage - Breakdown (VBR):** 44.4V (Min), 49.1V (Typ), 53.8V (Max)  
- **Voltage - Clamping (Vc):** 64.5V at 10A (IPP)  
- **Current - Peak Pulse (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (Pppm):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**  
- **Type:** Uni-directional TVS diode  
- **Application:** Protects sensitive electronics from voltage transients, ESD, and surges.  
- **Compliance:** RoHS compliant  

### **Features:**  
- Fast response time (low clamping voltage)  
- High surge capability  
- Low leakage current  
- Compact SMB package for space-saving designs  
- Suitable for automotive, industrial, and consumer electronics  

This information is based on CONCORD's datasheet for the SMBJ40A TVS diode.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB43A --: Same SMB package unidirectional TVS with a close standoff voltage (43V vs 40V) and comparable clamping, widely available from a major brand.
  • 1SMB40AT3G --: SMB-packaged 40V unidirectional TVS diode with matching working voltage and similar surge rating, from a well-established supplier.
  • SMAJ40A --: Same 40V standoff unidirectional TVS in the smaller SMA package; acceptable if board space allows and surge requirements are slightly relaxed.
  • 1SMB40A --: Unidirectional 400W-class SMB TVS diode with 40V standoff, matching the SMBJ40A rating and footprint from a different series and vendor.
  • P6SMB40A --: Same SMB package unidirectional 40V standoff TVS with comparable clamping voltage and peak pulse power, widely available and pin-compatible.
