Description and Introduction

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 170 V. Test current IT = 1 mA. The SMCJ170CA is a Transient Voltage Suppressor (TVS) diode manufactured by **Microsemi**. Below are its key specifications, descriptions, and features:

### **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 waveform)  
- **Power - Peak Pulse (P_PP):** 1500W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Description:**  
The SMCJ170CA is a **bidirectional** TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching. It meets **IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge)** standards.  

### **Features:**  
- **Bidirectional clamping** for AC or bipolar signal lines.  
- **Low clamping voltage** for superior transient protection.  
- **Fast response time** (typically <1ps).  
- **High surge capability** (1500W peak pulse power).  
- **RoHS compliant**.  
- **AEC-Q101 qualified** for automotive applications.  

For detailed datasheets, refer to **Microsemi’s official documentation**.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 170 V. Test current IT = 1 mA.

Alternative Part Number

  • 1.5SMC170CA --: Same 1500W SMC package bidirectional TVS with 170V standoff voltage; widely available and electrically equivalent.
  • SMDJ170CA --: 3000W SMC-size bidirectional TVS at 170V standoff; higher surge rating makes it a robust drop-in upgrade in the same footprint.
  • P6SMB170CA --: 600W SMB bidirectional TVS at 170V standoff; lower power rating but suitable if surge requirements are reduced, from a different series and manufacturer.
  • SMAJ170CA --: Bidirectional 400W TVS with 170V standoff voltage; compact SMA package option for lower-power protection needs.
