Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ43CA is a transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 43V  
- **Voltage - Breakdown (V_BR):** 47.8V (Min)  
- **Voltage - Clamping (V_C):** 69.4V at 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  
- **Polarity:** Bidirectional  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients.  
- Features low incremental surge resistance for effective clamping.  
- Bidirectional configuration allows protection against both positive and negative voltage spikes.  

### **Features:**  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond).  
- **High Surge Capability:** Handles high transient currents.  
- **RoHS Compliant:** Meets environmental standards.  
- **Low Leakage Current:** Ensures minimal power loss during normal operation.  

This information is sourced from Fairchild Semiconductor's official datasheet for the SMAJ43CA.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB43CA --: Bidirectional TVS diode with 43V standoff voltage in SMB package, similar clamping performance and a different series/prefix for easy distinction.
  • SMBJ43CA --: Direct functional equivalent bidirectional TVS in SMB (DO-214AA) with 43V standoff, widely available from a different manufacturer and series.
  • 1SMB43CAT3G --: Bidirectional 43V TVS diode in SMB package with comparable surge rating, offered under a distinct onsemi naming scheme.
