Description and Introduction

SMD Transient Voltage Suppressor The SMCJ190CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by FAIRCHILD.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 190V  
- **Voltage - Breakdown (V_BR):** 211V (Min)  
- **Voltage - Clamping (V_C):** 308V at 10A (Typ)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 1500W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Description:**  
The SMCJ190CA is designed to protect sensitive electronics from high-voltage transients, including ESD, lightning, and inductive load switching. It features low clamping voltage and fast response time.  

### **Features:**  
- **Bidirectional protection**  
- **Low incremental surge resistance**  
- **High reliability**  
- **RoHS compliant**  
- **UL recognized**

Application Scenarios & Design Considerations

SMD Transient Voltage Suppressor

Alternative Part Number

  • 1.5SMC190CA --: Same 1500W bidirectional TVS class with 190V standoff voltage, widely available and pin-compatible in SMC package.
  • P6SMB190CA --: Bidirectional 600W TVS with matching 190V standoff, suitable for lower-surge clamping applications and easy to source.
  • SMAJ190CA --: Bidirectional TVS with 190V standoff in SMA package, good drop-in for space-constrained designs needing similar clamping.
  • 1.5SMC200CA --: Same SMC (DO-214AB) package bidirectional TVS with comparable 1500W peak pulse power and a close standoff voltage, making it a strong drop-in replacement.
  • SMDJ190CA --: Higher-power 3000W SMD TVS in the same DO-214AB footprint with matching 190V standoff and bidirectional clamping, offering extra surge margin.
  • TPSMC200CA --: Automotive-grade 1500W bidirectional TVS in SMC package with similar standoff voltage, suitable when AEC-Q101 qualification is desired.
  • P6SMB200CA --: Bidirectional SMB-package TVS diode with 600W rating and close clamping characteristics, offering a lower-power alternative when full 1500W surge capability is not required.
