Description and Introduction

High junction temperature Transil The SMA6J40A-TR is a transient voltage suppressor (TVS) diode manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** STMicroelectronics  
- **Part Number:** SMA6J40A-TR  
- **Package:** SMA (DO-214AC)  
- **Mounting Type:** Surface Mount  
- **Peak Pulse Power (PPP):** 600W (10/1000μs)  
- **Breakdown Voltage (VBR):** 44.4V (min), 49.2V (typ), 54.0V (max)  
- **Standoff Voltage (VRWM):** 40V  
- **Clamping Voltage (VC):** 64.5V (at IPP = 1A)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**
- The SMA6J40A-TR is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, electrostatic discharge (ESD), and electrical fast transients (EFT).  
- It is compliant with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) standards.  

### **Features:**
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Can handle high transient energy pulses.  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond response).  
- **Unidirectional Configuration:** Protects against positive voltage transients.  
- **RoHS Compliant:** Meets environmental standards.  

This information is strictly based on the manufacturer's datasheet and knowledge base.

Application Scenarios & Design Considerations

High junction temperature Transil

Alternative Part Number

  • SMBJ40A --: Same 40V standoff unidirectional TVS in SMB package with comparable clamping and surge rating, widely available and pin-compatible.
  • P6SMB40A --: 600W unidirectional TVS diode with 40V standoff in SMB, similar surge capability and footprint to the SMA6J series.
  • SMAJ40A --: 400W unidirectional TVS with 40V standoff in SMA package, lower power rating but same form factor and voltage class for less demanding clamping needs.
