Description and Introduction

Silicon Avalanche Diodes - 1500W Surface Mount Transient Voltage Supressors The SMCJ180A is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients and surges.  

### **Manufacturer Specifications:**  
- **Manufacturer:** Littelfuse (or other manufacturers like Vishay, STMicroelectronics, etc., depending on availability)  
- **Peak Pulse Power:** 1500W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 200V (min) – 222V (max)  
- **Clamping Voltage (VC):** 292V at 10A  
- **Standoff Voltage (VRWM):** 180V  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ180A is a unidirectional TVS diode, meaning it clamps positive voltage transients.  
- It is designed for high-speed overvoltage protection in circuits.  
- Commonly used in telecom, industrial, and automotive applications.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **High Surge Capability:** Can handle large transient currents.  
- **RoHS Compliant:** Meets environmental standards.  
- **Unidirectional Polarity:** Suitable for DC circuits.  

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

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 1500W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • 1SMC180A --: Same 1500W unidirectional TVS diode with 180V standoff voltage and SMC package, direct functional equivalent from a different series naming.
  • P6SMB180A --: Unidirectional TVS with matching 180V standoff and SMB package; lower peak power rating (600W) but suitable for lower surge applications.
  • SMAJ180A --: Unidirectional 180V standoff TVS in SMA package; smaller 400W rating, usable where board space is tight and surge energy is lower.
  • 1.5SMC180A --: Same 1500W peak pulse power and 180V standoff unidirectional TVS in the 1.5SMC series, a widely available drop-in replacement with equivalent clamping performance.
  • 1.5SMC200A --: Same SMC (DO-214AB) package unidirectional TVS with comparable 1500W peak pulse power and a close standoff voltage, making it a strong drop-in choice.
  • SMDJ180A --: Surface-mount unidirectional TVS in the same SMC footprint with 3000W rating and matching 180V standoff, offering higher surge margin.
  • P6SMB200A --: Unidirectional TVS with similar clamping behavior and 600W rating in SMB package; suitable when lower power and smaller footprint are acceptable.
