Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMBJ17A is a transient voltage suppressor (TVS) diode manufactured by Microsemi (now part of Microchip Technology). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V₃₃₀):** 17V  
- **Voltage - Breakdown (VBR):** 18.8V (min)  
- **Voltage - Clamping (VCL):** 27.4V at 1A  
- **Peak Pulse Current (IPP):** 19.4A (8/20µs pulse)  
- **Power - Peak Pulse (PPK):** 600W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  

### **Description:**  
The SMBJ17A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, such as ESD (electrostatic discharge), lightning, and other surge events. It offers high surge capability and fast response time.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **High Surge Capability:** Handles large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Unidirectional Operation:** Protects against positive voltage transients.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based on Microsemi's datasheet for the SMBJ17A TVS diode. For exact details, refer to the official documentation.

Application Scenarios & Design Considerations

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • P6SMB17A --: Same 600W peak pulse power, 17V standoff unidirectional TVS in SMB package; different series name and widely available equivalent.
  • 1SMB17AT3G --: 600W SMB unidirectional TVS with 17V standoff and similar clamping voltage; established alternative with different naming.
  • SMAJ17A --: 400W SMA TVS with same 17V standoff; lower power rating but usable in less demanding clamping applications and clearly different series.
