Description and Introduction

TRANSIL The SMCJ8.5A-TR is a surface-mount transient voltage suppressor (TVS) diode manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 8.5V  
- **Voltage - Breakdown (VBR):** 9.45V (min) @ 1mA  
- **Voltage - Clamping (VC):** 13.9V @ 10A  
- **Peak Pulse Current (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (PPP):** 1500W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  
- **Mounting Type:** Surface Mount  

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

For detailed technical information, refer to the official STMicroelectronics datasheet.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • 1SMC8.5AT3G --: Same 1500W unidirectional TVS class with 8.5V standoff voltage, similar SMC package and surge rating, widely available drop-in alternative.
  • SMAJ8.5A --: Unidirectional TVS with matching 8.5V standoff voltage; lower power rating (400W) so suitable only for reduced surge requirements, but pin-compatible in SMA footprint.
  • P6SMB8.5A --: Unidirectional 600W TVS with 8.5V standoff voltage, good electrical match for lower-power designs and commonly stocked alternative.
