Description and Introduction

TRANSIL The SMBJ8.5CA-TR is a surface-mount bidirectional TVS (Transient Voltage Suppressor) diode manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 8.5V  
- **Voltage - Breakdown (V_BR):** 9.44V (Min)  
- **Voltage - Clamping (V_CL):** 13.9V at 1A  
- **Peak Pulse Current (I_PP):** 24.1A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Bidirectional  

### **Descriptions:**  
The SMBJ8.5CA-TR is designed to protect sensitive electronics from voltage transients, including ESD (Electrostatic Discharge), lightning, and other surge events. It provides bidirectional clamping, meaning it suppresses both positive and negative voltage spikes.  

### **Features:**  
- **Low Clamping Voltage** for effective protection  
- **Fast Response Time** (<1ns)  
- **High Surge Current Capability**  
- **RoHS Compliant**  
- **AEC-Q101 Qualified** (for automotive applications)  
- **Reliable Performance** in harsh environments  

This device is commonly used in power supplies, communication systems, automotive electronics, and industrial applications.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • P6SMB10CA --: Bidirectional TVS diode in the P6SMB series with comparable 600W peak pulse power and a standoff voltage close to the SMBJ8.5CA, suitable for similar transient protection.
  • SMAJ8.5CA --: Bidirectional TVS in the SMAJ series with the same 8.5V standoff voltage and SMA package, offering a lower-power but pin-compatible alternative.
  • 1.5SMC10CA --: Bidirectional TVS in the 1.5SMC series with higher 1500W surge rating and a nearby standoff voltage, usable where extra clamping margin is acceptable.
