Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power The SMDJ15A is a Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Part Number:** SMDJ15A  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** Uni-directional TVS Diode  
- **Peak Pulse Power (PPP):** 1500W (10/1000μs)  
- **Breakdown Voltage (VBR):** 16.7V (min)  
- **Standoff Voltage (VRWM):** 15V  
- **Clamping Voltage (VC):** 24.4V at 16.5A  
- **Peak Pulse Current (IPP):** 62.5A (8/20μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**
- Designed to protect sensitive electronics from voltage transients and surges.  
- Suitable for applications requiring high power dissipation in a compact package.  
- Compliant with RoHS standards.  

### **Features:**
- **Fast Response Time:** Responds quickly to transient events.  
- **High Surge Capability:** Handles large surge currents.  
- **Low Clamping Voltage:** Provides effective protection for downstream components.  
- **Uni-directional Polarity:** Protects against positive transients.  
- **SMC Package:** Compact surface-mount design for PCB integration.  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 1.5SMC15A --: Same 1500W peak pulse power class and 15V standoff unidirectional TVS in the SMC (DO-214AB) package, directly interchangeable for surge protection.
  • SMCJ15A --: 1500W unidirectional TVS with 15V standoff in SMC package; same clamping behavior and footprint, widely used as a drop-in substitute.
  • P6SMB15A --: 600W 15V unidirectional TVS in smaller SMB package; suitable when lower surge rating is acceptable and board space is limited.
  • 1SMB15AT3G --: Unidirectional 15V standoff TVS diode in SMB package with similar 600W-class surge rating, widely available and pin-compatible for SMDJ15A replacement.
  • SMAJ15A --: 400W unidirectional 15V TVS diode in SMA package; lower power rating but a common drop-in style alternative when surge requirements are moderate.
