Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ40CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology).  

### **Specifications:**  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000μs)  
- **Working Voltage (VWM):** 40V  
- **Breakdown Voltage (VBR):** 44.4V (min) to 49.1V (max)  
- **Clamping Voltage (VC):** 64.5V (max) at 1A  
- **Peak Pulse Current (IPP):** 6.2A (8/20μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
The SMDJ40CA is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching events. It provides bidirectional clamping to safeguard circuits from both positive and negative surges.  

### **Features:**  
- Low incremental surge resistance  
- Fast response time  
- High reliability  
- RoHS compliant  
- Lead-free and halogen-free  

This device is commonly used in telecommunications, industrial controls, and power supply protection applications.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 5.0SMDJ40CA --: Same 40V bidirectional TVS in the 5.0SMDJ series with equivalent SMD package and surge rating, widely available and a direct functional drop-in.
  • SMCJ40CA --: Bidirectional 40V TVS in SMC (DO-214AB) package with similar clamping and power handling, a common cross-reference for SMDJ40CA.
  • 1.5SMC40CA --: Bidirectional 40V TVS in SMC package offering comparable protection characteristics, suitable when slightly lower peak pulse power is acceptable.
