Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ85A is a transient voltage suppressor (TVS) diode manufactured by Microsemi (MIC). Here are the factual details about the part:  

### **Manufacturer:**  
- **MIC (Microsemi)**  

### **Specifications:**  
- **Peak Pulse Power:** 400W (8/20μs waveform)  
- **Breakdown Voltage (VBR):** 94.05V (min) – 103.95V (max)  
- **Standoff Voltage (VRWM):** 85V  
- **Clamping Voltage (VC):** 137V (at IPP = 1A)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VRWM)  
- **Junction Capacitance (CJ):** 50pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
- The SMAJ85A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching.  
- It is compliant with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  
- The device is housed in a **DO-214AC (SMA) package**, making it suitable for surface-mount applications.  

### **Features:**  
- **Fast response time** (typically <1ps)  
- **Low clamping voltage** for effective protection  
- **High surge capability**  
- **RoHS compliant**  
- **Unidirectional polarity** (protects against positive transients only)  

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

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB91A --: Same 400W-class unidirectional TVS in SMB package with 91V standoff, close to SMAJ85A's 85V rating and a widely available drop-in style alternative.
  • SMBJ85A --: Direct 85V unidirectional TVS in SMB with matching 600W surge rating, electrically equivalent and from a different series naming.
  • 1SMB85AT3G --: 85V unidirectional SMB TVS with comparable clamping and power handling, offered under a distinct 1SMB series prefix for easy differentiation.
  • SMAJ85A-E3/61 --: Same SMAJ series 400W unidirectional TVS with 85V standoff and 5% tolerance, direct electrical equivalent from a major supplier.
  • P4SMA85A --: 400W SMA-package unidirectional TVS with matching 85V standoff and clamping characteristics, suitable drop-in replacement.
  • SMAJ85A-TR --: Equivalent 400W SMA TVS diode with 85V working voltage and 5% breakdown tolerance, widely available alternative.
  • P6SMB100A --: SMB-packaged unidirectional TVS with comparable 85V standoff class and higher peak pulse power, widely available and pin-compatible.
