Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ54CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Part Number:** SMDJ54CA  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 60.1V (min) to 66.4V (max)  
- **Standoff Voltage (VRWM):** 54V  
- **Clamping Voltage (VC):** 87.4V at 10A  
- **Peak Pulse Current (IPP):** 17.2A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**
- Designed for surge protection in sensitive electronics.  
- Bidirectional configuration protects against both positive and negative transient voltages.  
- Suitable for high-speed data lines and power supply protection.  

### **Features:**
- **High Power Handling:** 1500W peak pulse power.  
- **Low Clamping Voltage:** Provides effective transient suppression.  
- **RoHS Compliant:** Meets environmental standards.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Surface Mount Package:** Compact and suitable for automated assembly.  

This information is based on LITTELFUSE's official datasheet for the SMDJ54CA.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 5.0SMDJ54CA --: Same 54V bidirectional TVS in the 5.0SMDJ series with higher 5000W peak pulse power, drop-in compatible footprint and improved surge rating.
  • SMCJ54CA --: Bidirectional 54V TVS in SMC (DO-214AB) package with 1500W rating; lower power but same clamping voltage class and widely available.
  • SMDJ54CA-T7 --: Equivalent 3000W bidirectional 54V TVS from an alternate manufacturer in the same SMC package, suitable as a second-source replacement.
