Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ28A is a Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Part Number:** SMDJ28A  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** TVS Diode (Unidirectional)  
- **Peak Pulse Power (PPP):** 3000W (10/1000μs)  
- **Breakdown Voltage (VBR):** 31.1V (min) – 34.4V (max)  
- **Standoff Voltage (VRWM):** 28V  
- **Clamping Voltage (VC):** 45.4V at 10A  
- **Peak Pulse Current (IPP):** 66.1A (8/20μs)  
- **Leakage Current (IR):** 1μA (max) at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Provides surge protection in compliance with IEC 61000-4-5 (8/20μs) and IEC 61000-4-4 (EFT).  
- Suitable for applications requiring high-power transient suppression.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for downstream components.  
- **High Surge Capability:** Handles large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **RoHS Compliant:** Meets environmental standards.  

For exact application details, always refer to the manufacturer’s datasheet.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 1SMB28AT3G --: Same 28V standoff unidirectional TVS in SMB package with comparable 3000W-class surge rating; widely available and pin-compatible.
  • SMAJ28A --: Same 28V standoff unidirectional TVS diode with similar clamping characteristics; smaller SMA package but suitable for lower-power drop-in use.
  • P6SMB28A --: 600W 28V unidirectional TVS in SMB package; lower surge rating than SMDJ but electrically compatible for many protection designs.
