Description and Introduction

Bi-directional transient voltage protection The **SMTBJ200A** is a **surface-mount transient voltage suppressor (TVS) diode** designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD). Below are its key specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Peak Pulse Power (PPP):** 200W (8/20μs waveform)  
- **Breakdown Voltage (VBR):** 33.3V (min) – 36.8V (max)  
- **Clamping Voltage (VC):** 58.1V at 1A (IPP)  
- **Reverse Standoff Voltage (VRWM):** 30V  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Peak Pulse Current (IPP):** 3.4A (8/20μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package Type:** SOD-323 (small surface-mount package)  

### **Descriptions:**
- Designed for **ESD protection** in high-speed data lines, USB ports, and other sensitive circuits.  
- **Unidirectional** TVS diode (conducts in one direction only).  
- Low clamping voltage ensures minimal stress on protected components.  

### **Features:**
- **Fast response time** (nanosecond-level reaction to transients).  
- **Low capacitance** (minimizes signal distortion in high-speed applications).  
- **RoHS compliant** (lead-free and environmentally friendly).  
- **AEC-Q101 qualified** (suitable for automotive applications).

Application Scenarios & Design Considerations

Bi-directional transient voltage protection

Alternative Part Number

  • SMAJ200A --: Same 200V standoff unidirectional TVS in the SMAJ series with similar 400W peak pulse power, widely available and a common drop-in for SMTBJ200A.
  • P6SMB200A --: 600W unidirectional TVS with 200V standoff in the SMB package, offering higher surge capability and a different series naming for easy distinction.
  • SMBJ200A --: 600W unidirectional TVS diode with 200V standoff in SMB package, a standard industry alternative with comparable clamping characteristics.
  • 1SMB200AT3G --: 1SMB series 200V unidirectional TVS diode in SMB package, suitable drop-in replacement with similar surge ratings.
