Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ24CA is a transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Part Number:** SMAJ24CA  
- **Manufacturer:** Fairchild Semiconductor (now ON Semiconductor)  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000µs waveform)  
- **Breakdown Voltage (VBR):** 26.7V (min)  
- **Standoff Voltage (VRWM):** 24V  
- **Clamping Voltage (VC):** 38.9V (at IPP = 1A)  
- **Peak Pulse Current (IPP):** 10.3A (8/20µs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Description:**  
The SMAJ24CA is designed to protect sensitive electronics from voltage transients, such as ESD (electrostatic discharge), lightning, and inductive load switching. It is a bidirectional TVS diode, meaning it clamps both positive and negative voltage spikes.

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive circuits.  
- **High Surge Capability:** Handles large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events (typically <1ns).  
- **Bidirectional Operation:** Protects against both positive and negative transients.  
- **RoHS Compliant:** Meets environmental standards.  

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

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB24CA --: Same 24V bidirectional TVS in SMB package with comparable peak pulse power, widely available and pin-compatible.
  • SMBJ24CA --: Direct SMB-packaged 24V bidirectional TVS with similar clamping voltage and surge rating, common cross-reference for SMAJ series.
  • 1SMB24CAT3G --: Same manufacturer's SMB 24V bidirectional TVS with equivalent electrical characteristics and drop-in footprint.
