Description and Introduction

Silicon Avalanche Diodes - 1500W Surface Mount Transient Voltage Supressors The SMCJ200A is a surface mount transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage transients and surges. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Peak Pulse Power (PPP):** 1500W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 222V to 246V (at 1mA)  
- **Standoff Voltage (VRWM):** 200V  
- **Clamping Voltage (VC):** 324V (at 16.5A)  
- **Peak Pulse Current (IPP):** 4.64A (8/20μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package Type:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ200A is a **bidirectional TVS diode**, meaning it can suppress both positive and negative voltage transients.  
- It is **surface-mountable**, making it suitable for compact PCB designs.  
- Designed for **high-speed protection** against ESD, lightning, and other transient voltage events.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Fast Response Time:** Typically responds in picoseconds to voltage spikes.  
- **High Surge Capability:** Can handle large transient currents.  
- **RoHS Compliant:** Meets environmental standards.  

The SMCJ200A is commonly used in **telecommunications, industrial equipment, and power supply protection** applications.  

(Note: Manufacturer details were not explicitly provided in Ic-phoenix technical data files.)

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 1500W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • 1.5SMC200A --: Same 200V standoff unidirectional TVS in the 1.5SMC series with comparable 1500W peak pulse rating, widely available and pin-compatible.
  • P6SMB200A --: 600W unidirectional TVS with 200V standoff in SMB package, suitable drop-in for lower surge applications and easily sourced.
  • SMAJ200A --: 400W unidirectional TVS with 200V standoff in SMA package, a compact alternative when lower peak pulse power is acceptable.
  • 1SMC200AT3G --: Same 200V standoff unidirectional TVS in SMC package with 1500W peak pulse rating, directly interchangeable.
  • 5.0SMDJ200A --: Higher 5000W surge-rated 200V unidirectional TVS in SMC package, suitable as a more robust drop-in replacement.
