Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMBJ70A is a transient voltage suppressor (TVS) diode manufactured by DIODE. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Voltage - Reverse Standoff (Typ):** 70V  
- **Voltage - Breakdown (Min):** 77.8V  
- **Voltage - Clamping (Max) @ Ipp:** 112V  
- **Current - Peak Pulse (10/1000µs):** 16.1A  
- **Power - Peak Pulse:** 600W  
- **Operating Temperature:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SMBJ70A is designed to protect sensitive electronics from voltage transients and surges.  
- It provides bi-directional protection (for both positive and negative voltage spikes).  
- Suitable for applications requiring high surge capability and fast response time.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Can handle large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events (typically in picoseconds).  
- **RoHS Compliant:** Meets environmental standards.  
- **Reliable Performance:** Robust construction for industrial and automotive applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Alternative Part Number

  • P6SMB70A --: Same 600W SMB package unidirectional TVS with 70V standoff and similar clamping, widely available drop-in replacement.
  • 1SMB70AT3G --: SMB-packaged 400W-class unidirectional TVS with 70V standoff; lower power rating but suitable for many surge protection designs.
  • SMAJ70A --: SMA package 400W unidirectional TVS with 70V standoff; smaller footprint alternative when board space allows reduced surge rating.
  • P6SMB75A --: Same SMB package unidirectional TVS with 75V standoff, close clamping voltage and 600W peak pulse rating, widely available drop-in substitute.
  • 1SMB75AT3G --: SMB-packaged 75V unidirectional TVS diode with comparable surge rating and clamping characteristics.
