Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ14CA is a Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Part Number:** SMDJ14CA  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** Bidirectional TVS Diode  
- **Working Voltage (VWM):** 14V  
- **Breakdown Voltage (VBR):** 15.6V (min) to 17.3V (max)  
- **Peak Pulse Current (IPP):** 24.2A (8/20μs waveform)  
- **Clamping Voltage (VC):** 22.5V at IPP  
- **Power Dissipation (PPPM):** 1500W (10/1000μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration allows clamping of both positive and negative voltage spikes.  
- Meets IEC 61000-4-5 (Lightning Immunity) and IEC 61000-4-4 (EFT) standards.  

### **Features:**  
- Low clamping voltage for effective protection.  
- High surge capability for robust performance.  
- RoHS compliant and halogen-free.  
- Fast response time to transient events.  
- Suitable for applications in telecommunications, industrial, and automotive systems.  

For exact details, always refer to the official datasheet from CCD.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 1SMC14CA --: Same 1500W SMC (DO-214AB) bidirectional TVS with 14V standoff, directly interchangeable.
  • SMCJ14CA --: Equivalent 1500W SMC bidirectional TVS diode with matching 14V working voltage and clamping characteristics.
  • 5.0SMDJ14CA --: Higher 5000W surge rating in the same SMC package, offering a robust upgrade while maintaining 14V bidirectional protection.
  • 1.5SMC15CA --: Same 1500W SMC-package bidirectional TVS class with a 15V standoff close to the SMDJ14CA, widely available and a common drop-in for 14V-15V clamping applications.
  • SMCJ15CA --: 1500W SMC bidirectional TVS diode with 15V standoff voltage, matching package and surge rating, from a different series naming so it is easily distinguished from the source.
  • 5.0SMDJ15CA --: 5000W SMC bidirectional TVS with 15V standoff; offers higher surge capability as an upgrade path while keeping the same SMC footprint and bidirectional clamping behavior.
