Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The **SMDJ11CA** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **LITTELFUSE**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Part Number:** SMDJ11CA  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 12.2V (min) – 13.5V (max)  
- **Standoff Voltage (VRWM):** 11V  
- **Clamping Voltage (VC):** 19.9V at 24.2A  
- **Peak Pulse Current (IPP):** 24.2A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed for **surge protection** in sensitive electronics.  
- **Bidirectional** operation protects against both positive and negative transients.  
- **Low clamping voltage** ensures effective protection for circuits.  

### **Features:**  
- **High surge capability** (1500W peak pulse power).  
- **Fast response time** to transient overvoltages.  
- **RoHS compliant** and lead-free.  
- **Automotive-grade** reliability (AEC-Q101 qualified).  

This device is commonly used in **power supplies, communication systems, and automotive electronics** for **ESD and surge protection**.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 1SMB11CAT3G --: Bidirectional 11V TVS diode in SMB package with similar clamping voltage and power rating, direct functional substitute.
  • P6SMB11CA --: Same manufacturer family, bidirectional 11V TVS in SMB package, comparable surge capability and clamping characteristics.
  • SMAJ11CA --: Bidirectional 11V TVS diode in SMA package, lower power rating but suitable for lower-surge applications as a fallback alternative.
  • SMCJ11CA --: Same 1500W bidirectional TVS class in SMC package with 11V standoff, widely available and electrically compatible.
  • 1.5SMC11CA --: 1500W bidirectional transient voltage suppressor with matching 11V working voltage and SMC footprint, suitable drop-in replacement.
  • TPSMD11CA --: 1500W surface-mount bidirectional TVS diode with 11V standoff voltage, comparable clamping performance and package compatibility.
