Description and Introduction

SMD Transient Voltage Suppressor The **SMAJ190CA** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **Microsemi** (now part of **Microchip Technology**). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Microsemi (Microchip)  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 211V (min) to 233V (max)  
- **Standoff Voltage (VRWM):** 190V  
- **Clamping Voltage (VC):** 308V at 1A  
- **Peak Pulse Current (IPP):** 1.3A (8/20μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Bidirectional configuration for AC or DC circuit protection.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- **Fast Response Time:** <1ps for transient suppression.  
- **High Surge Capability:** Handles large transient currents.  
- **RoHS Compliant:** Lead-free and environmentally friendly.  
- **Reliable Performance:** Meets industrial and automotive standards.  

This diode is commonly used in **power supplies, telecom equipment, and automotive systems** for overvoltage protection.  

(Note: Always verify datasheet details for application-specific requirements.)

Application Scenarios & Design Considerations

SMD Transient Voltage Suppressor

Alternative Part Number

  • P6SMB200CA --: Bidirectional TVS diode in SMB package with comparable standoff voltage and clamping performance, suitable drop-in replacement for transient protection.
  • 1.5SMC200CA --: Bidirectional 1500W TVS in SMC package offering similar surge capability and voltage rating, widely available alternative.
  • SMBJ190CA --: Same SMB footprint and 190V bidirectional standoff rating, direct functional equivalent from a different series and manufacturer.
  • 1SMB190CA --: Bidirectional 190V standoff TVS in SMB package, direct functional equivalent with similar surge rating.
