Description and Introduction

TRANSIL The SM6T18CA is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Vishay  
- **Part Number:** SM6T18CA  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000µs):** 600 W  
- **Breakdown Voltage (VBR):** 20.0 V (min) – 22.2 V (max)  
- **Standoff Voltage (VRWM):** 18 V  
- **Clamping Voltage (VC):** 29.2 V (at IPP = 5 A)  
- **Maximum Peak Pulse Current (IPP):** 20.5 A  
- **Leakage Current (IR):** 1 µA (max at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

### **Descriptions:**
- Designed to protect sensitive electronics from voltage transients induced by lightning, ESD, and other transient voltage events.  
- Bidirectional configuration allows it to clamp both positive and negative transients.  
- Low clamping voltage ensures effective protection for downstream components.  

### **Features:**
- High surge capability (600 W peak pulse power).  
- Fast response time to transient overvoltages.  
- RoHS compliant and halogen-free.  
- Suitable for applications in automotive, industrial, and telecommunications systems.  

For detailed datasheet information, refer to Vishay’s official documentation.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • SMBJ18CA --: Same SMB (DO-214AA) package, 18V bidirectional standoff, 600W peak pulse power; direct functional equivalent to the SM6T18CA.
  • P6SMB18CA --: 600W bidirectional TVS in SMB package with 18V standoff voltage, matching the SM6T18CA's clamping and surge ratings.
  • 1SMB18CAT3G --: SMB-packaged 600W bidirectional transient voltage suppressor with 18V working voltage, suitable drop-in replacement for the SM6T18CA.
