Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ45A is a unidirectional TVS (Transient Voltage Suppressor) diode manufactured by CONCORD. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (8/20µs waveform)  
- **Breakdown Voltage (VBR):** 50.1V (min) to 55.4V (max)  
- **Standoff Voltage (VRWM):** 45V  
- **Clamping Voltage (VC):** 73.2V at 1A (IPP)  
- **Peak Pulse Current (IPP):** 5.47A (8/20µs)  
- **Leakage Current (IR):** 1µA (max) at VRWM  
- **Junction Capacitance (CJ):** 500pF (max) at 1MHz, 0V bias  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Unidirectional polarity, meaning it clamps positive voltage spikes.  
- Fast response time (typically <1ns).  

### **Features:**  
- High surge capability.  
- Low clamping voltage.  
- RoHS compliant.  
- Lead-free and halogen-free.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

This information is strictly based on the manufacturer's datasheet for the SMAJ45A TVS diode.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P4SMAJ45A --: Same 400W SMA-pack unidirectional TVS with 45V standoff, direct electrical equivalent from a different series.
  • SMAJ45A-E3/61 --: Vishay SMAJ series 400W TVS, same 45V standoff and SMA package, widely available drop-in replacement.
  • 1SMA45AT3G --: 400W SMA-pack unidirectional TVS with 45V standoff, different naming series, suitable functional substitute.
  • P6SMB51A --: SMB-packaged unidirectional TVS diode with a comparable standoff voltage and clamping performance, widely available and a common drop-in substitute for SMAJ45A.
  • SMBJ45A --: Same SMB footprint and 45V standoff unidirectional TVS diode, offering equivalent surge protection with a different series name for easy distinction.
  • 1SMB45AT3G --: SMB unidirectional TVS diode rated at 45V standoff with similar peak pulse power, suitable as an alternative from a different product family.
  • P4SMA45A --: 400W SMA-pack unidirectional TVS with 45V standoff from the same manufacturer, same footprint and ratings.
  • SMAJ45A-TR --: Equivalent 400W SMA unidirectional transient voltage suppressor with 45V working voltage, suitable drop-in replacement.
