Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ14A is a transient voltage suppressor (TVS) diode manufactured by CONCORD. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 14V  
- **Voltage - Breakdown (V_BR):** 15.6V (min)  
- **Voltage - Clamping (V_C):** 22.5V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 400W (8/20μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMAJ14A is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching.  
- It offers low clamping voltage and fast response time.  
- RoHS compliant and halogen-free.  

### **Features:**  
- High surge capability (400W peak pulse power).  
- Low incremental surge resistance.  
- Fast response time (typically <1ps).  
- Bidirectional TVS diode (for SMAJ14A, unidirectional variants may also exist).  
- Suitable for high-speed data line protection.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P4SMAJ14A --: Same SMA package unidirectional 400W TVS with 14V standoff voltage, direct electrical equivalent from a major supplier.
  • SMAJ14A-E3/61 --: Vishay's SMAJ series 400W TVS diode with matching 14V standoff and SMA footprint, widely available and reliable.
  • 1SMA14AT3G --: 400W SMA-packaged unidirectional TVS with 14V standoff, functionally interchangeable with the SMAJ14A.
  • SMAJ14A-TR --: ST's SMAJ TVS diode matches the 400W rating, 14V standoff, and SMA footprint for direct drop-in replacement.
