Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ120A is a transient voltage suppressor (TVS) diode manufactured by CCD (Continental Device India Limited). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Part Number:** SMDJ120A  
- **Manufacturer:** CCD (Continental Device India Limited)  
- **Type:** Transient Voltage Suppressor (TVS) Diode  
- **Peak Pulse Power:** 3000W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 133.4V (min) to 147.4V (max)  
- **Standoff Voltage (VRWM):** 120V  
- **Clamping Voltage (VC):** 193V at 10A  
- **Peak Pulse Current (IPP):** 15.5A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMDJ120A is designed to protect sensitive electronics from voltage transients and surges.  
- It provides bidirectional protection, clamping voltage spikes to safe levels.  
- Suitable for high-speed data lines, power supplies, and industrial applications.  

### **Features:**  
- Low clamping voltage  
- High surge capability  
- RoHS compliant  
- Fast response time  
- Bidirectional polarity  

This information is based on CCD's datasheet for the SMDJ120A TVS diode.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power

Alternative Part Number

  • 1.5SMC120A --: Same 120V standoff unidirectional TVS in a comparable SMC package with similar surge rating, widely available and pin-compatible for most layouts.
  • SMAJ120A --: Unidirectional 120V TVS with matching working voltage and clamping behavior; smaller SMA package suits lower-power designs but is a common drop-in when surge energy is modest.
  • P6SMB120A --: 120V unidirectional TVS diode in SMB package offering similar protection characteristics; good second-source option when SMC footprint space is flexible.
  • SMCJ120A --: Unidirectional 120V standoff TVS diode in SMC package with 1500W peak pulse power, a direct functional substitute for the SMDJ120A.
  • 5.0SMDJ120A --: Higher 5000W peak pulse power unidirectional TVS at 120V standoff in the same SMC footprint, offering extra surge margin as a drop-in upgrade.
