Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ12A is a transient voltage suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Part Number:** SMDJ12A  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** Uni-directional TVS Diode  
- **Peak Pulse Power (PPP):** 1500W (10/1000μs)  
- **Breakdown Voltage (VBR):** 13.3V (min) – 14.7V (max)  
- **Standoff Voltage (VRWM):** 12V  
- **Clamping Voltage (VC):** 19.9V (at IPP = 16.5A)  
- **Peak Pulse Current (IPP):** 16.5A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMDJ)  

### **Descriptions:**  
- Designed for surge protection in electronic circuits.  
- Protects sensitive components from voltage transients, ESD, and lightning-induced surges.  
- Suitable for applications requiring high power dissipation in a compact package.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Withstands large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **RoHS Compliant:** Meets environmental standards.  
- **Uni-directional Polarity:** Protects against positive voltage transients.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 1SMB12AT3G --: Same 12V standoff unidirectional TVS in SMB package with comparable 600W-class surge rating; widely available and pin-compatible.
  • P6SMB12A --: 600W unidirectional TVS diode with 12V standoff in SMB (DO-214AA) package, matching clamping behavior for similar transient protection.
  • SMAJ12A --: 12V standoff unidirectional TVS in SMA package; lower power rating (400W) but suitable as a drop-in for lower-energy surge applications.
