Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ48A is a Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Part Number:** SMDJ48A  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 53.3V (Min), 58.9V (Max)  
- **Standoff Voltage (VRWM):** 48V  
- **Clamping Voltage (VC):** 77.4V at 24.3A  
- **Peak Pulse Current (IPP):** 24.3A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration for protection against both positive and negative voltage spikes.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

### **Features:**  
- High surge capability for robust protection.  
- Low clamping voltage for effective transient suppression.  
- RoHS compliant and lead-free.  
- Fast response time to transient events.  

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

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power

Alternative Part Number

  • SMAJ48A --: Same 48V standoff unidirectional TVS diode in the SMAJ series; lower power rating but pin-compatible and widely available for less demanding surge protection.
  • SMCJ48A --: Same 48V standoff unidirectional TVS in SMC package with 1500W peak pulse power, close electrical match to the 3000W SMDJ48A for many clamping applications.
  • 5.0SMDJ48A --: 5000W 48V unidirectional TVS in SMD package offering higher surge capability than SMDJ48A, suitable as an upgraded drop-in alternative.
  • 1SMB48AT3G --: Unidirectional 48V SMB TVS diode with similar standoff voltage and peak pulse power, suitable drop-in replacement for transient protection.
  • P6SMB48A --: Same manufacturer SMB package 48V unidirectional TVS with comparable clamping performance, easy second source within the same brand.
