Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ30CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Part Number:** SMDJ30CA  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power:** 3000W (10/1000µs)  
- **Breakdown Voltage (VBR):** 33.3V (min) – 36.8V (max)  
- **Standoff Voltage (VRWM):** 30V  
- **Clamping Voltage (VC):** 48.4V at 10A  
- **Peak Pulse Current (IPP):** 62.5A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMDJ)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Bidirectional configuration for AC or bipolar signal protection.  
- Low clamping voltage for effective transient suppression.  

### **Features:**  
- High surge capability (3000W).  
- Fast response time (pico-second range).  
- RoHS compliant.  
- Lead-free and halogen-free.  

This information is strictly factual from the available knowledge base.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • SMCJ30CA --: Same 1500W bidirectional TVS in SMC package with 30V standoff; lower power rating than SMDJ but often acceptable and widely available.
  • 5.0SMDJ30CA --: 5000W bidirectional TVS with identical 30V standoff voltage and SMC footprint, offering higher surge capability as a drop-in upgrade.
  • SMDJ30A --: Unidirectional version of the same 3000W SMDJ series with matching 30V standoff; suitable if bidirectional clamping is not strictly required.
  • 1.5SMC30CA --: 1500W bidirectional TVS at 30V standoff in SMC package, matching the SMDJ30CA's clamping role and footprint for most surge protection designs.
  • TPSMC30CA --: Automotive-grade 30V bidirectional TVS in SMC package with similar power rating, suitable when higher reliability or AEC-Q101 qualification is needed.
