Description and Introduction

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 170 V. Test current IT = 1 mA. The SMBJ170CA is a Transient Voltage Suppressor (TVS) diode manufactured by MICROSEMI.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 170V  
- **Voltage - Breakdown (V_BR):** 189V (Min)  
- **Voltage - Clamping (V_C):** 274V at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  
- **Polarity:** Unidirectional  

### **Descriptions and Features:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Fast response time to transient overvoltage events.  
- Low incremental surge resistance for effective clamping.  
- RoHS compliant.  
- Suitable for applications in telecommunications, industrial, and automotive systems.  

This device is commonly used for ESD protection, lightning suppression, and overvoltage protection in circuits.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 170 V. Test current IT = 1 mA.

Alternative Part Number

  • P6SMB170CA --: Same SMB package, 600W bidirectional TVS with 170V standoff voltage, direct functional equivalent from a different series.
  • 1SMB170CA --: SMB-packaged 600W bidirectional TVS diode with matching 170V standoff, widely available alternative with different naming.
  • SMAJ170CA --: Similar 400W bidirectional TVS in SMA package with 170V standoff; lower power rating but usable in less demanding clamping applications.
  • 1SMB170CAT3G --: 600W SMB bidirectional transient voltage suppressor with matching 170V working voltage and clamping characteristics.
