Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ14CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by Microsemi. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Part Number:** SMAJ14CA  
- **Manufacturer:** Microsemi  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 400W  
- **Breakdown Voltage (VBR):** 15.6V (min) – 17.3V (max)  
- **Standoff Voltage (VRWM):** 14V  
- **Clamping Voltage (VC):** 22.5V (at IPP = 1A)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration allows clamping of both positive and negative voltage spikes.  
- Compliant with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

### **Features:**
- **Low Clamping Voltage:** Provides effective protection for low-voltage circuits.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **High Surge Capability:** Handles high transient currents.  
- **RoHS Compliant:** Environmentally friendly component.  
- **Reliable Performance:** Ensures long-term protection in harsh environments.  

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

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB15CA --: Bidirectional TVS diode in SMB package with comparable 14V standoff class and similar clamping performance; widely available and a common drop-in substitute.
  • SMBJ14CA --: Same SMB package and 14V bidirectional standoff rating as the original, offering equivalent surge protection with a different series name for easy distinction.
  • 1SMB15CAT3G --: Bidirectional SMB TVS diode with close standoff voltage and similar peak pulse power, suitable as a functional replacement from a major supplier.
