Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ9.0CA is a transient voltage suppressor (TVS) diode manufactured by **FAIRCHILD**. Below are its specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 9.0V  
- **Voltage - Breakdown (V_BR):** 10.0V (min)  
- **Peak Pulse Power (P_PPM):** 400W (8/20μs waveform)  
- **Clamping Voltage (V_C):** 14.5V (at I_PP = 1A)  
- **Maximum Reverse Leakage Current (I_R):** 1μA (at V_RWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMAJ9.0CA is a **bidirectional** TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching.  
- It is compliant with **IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge)** standards.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive circuits.  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond response).  
- **High Surge Capability:** Handles high transient power dissipation.  
- **Bidirectional Operation:** Protects against both positive and negative voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed performance curves and application notes, refer to the official **FAIRCHILD datasheet**.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ9.0CA --: Same 9.0V bidirectional TVS diode in a larger SMB package, offering higher surge power capability and a drop-in functional replacement for SMAJ9.0CA.
  • P6SMB9.0CA --: Bidirectional 9.0V TVS diode in SMB package with comparable clamping voltage and peak pulse power, suitable as a direct functional substitute.
  • 1SMB9.0CA --: Bidirectional 9.0V TVS diode in SMB package with similar standoff voltage and surge rating, providing a reliable alternative from a different series.
  • 1.5SMC9.0CA --: Bidirectional 9.0V TVS in SMC package offering higher peak pulse power, usable as a robust substitute where a larger package fits.
  • SMAJ9.0CA-TR --: Equivalent 400W bidirectional TVS in SMA package with same 9.0V working voltage, from a major supplier with good availability.
