Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ170A is a Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 170V  
- **Voltage - Breakdown (V_BR):** 189V (Min)  
- **Voltage - Clamping (V_C):** 274V @ 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 1500W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Description:**  
The SMDJ170A is a surface-mount TVS diode designed to protect sensitive electronics from high-voltage transients, such as ESD, lightning, and inductive load switching. It offers robust clamping performance for surge protection in industrial, automotive, and communication applications.  

### **Features:**  
- Low clamping voltage  
- Fast response time  
- High surge capability  
- RoHS compliant  
- Lead-free and halogen-free  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power

Alternative Part Number

  • 1.5SMC170A --: Same 1500W SMC package and 170V standoff unidirectional TVS, widely available and electrically equivalent for most surge protection designs.
  • SMCJ170A --: 1500W SMC unidirectional TVS with matching 170V standoff and clamping characteristics, from a different series and manufacturer for easy distinction.
  • TPSMD170A --: Automotive-grade 3000W SMC TVS with the same 170V standoff; higher surge rating provides margin while remaining footprint-compatible.
  • 5.0SMDJ170A --: Higher 5000W surge-rated SMC TVS at the same 170V standoff, offering extra margin while keeping the same footprint and polarity.
