Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ160CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by Vishay. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Voltage - Reverse Standoff (Typ):** 160V  
- **Voltage - Breakdown (Min):** 178V  
- **Voltage - Clamping (Max) @ Ipp:** 259V  
- **Current - Peak Pulse (10/1000µs):** 24.2A  
- **Power - Peak Pulse:** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed for surge protection in electronic circuits.  
- Bidirectional polarity for clamping both positive and negative transients.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- **High Surge Capability:** Withstands high transient currents.  
- **Fast Response Time:** Reacts quickly to overvoltage transients.  
- **RoHS Compliant:** Meets environmental standards.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  
- **Low Leakage Current:** Ensures minimal power loss in standby mode.  

This diode is commonly used in power supplies, communication systems, and automotive electronics for transient voltage suppression.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ160CA --: Same 160V bidirectional TVS in a larger SMB package with higher surge rating; widely available and pin-compatible in layout with adequate pad size.
  • P6SMB160CA --: 600W bidirectional TVS with 160V standoff in SMB package, matching the SMAJ160CA's clamping role with extra surge margin.
  • 1SMB160CA --: Bidirectional 160V TVS in SMB package offering similar clamping voltage and a different series naming for easy distinction.
  • 1.5SMC160CA --: Bidirectional 160V TVS diode with similar surge rating and SMC footprint, suitable when slightly higher power handling is acceptable.
