Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ90CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000μs)  
- **Breakdown Voltage (VBR):** 100V (min)  
- **Standoff Voltage (VRWM):** 90V  
- **Clamping Voltage (VC):** 146V (max) at 1A  
- **Leakage Current (IR):** 1μA (max) at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Bidirectional configuration allows clamping of both positive and negative voltage spikes.  
- RoHS compliant.  

### **Features:**  
- **Fast Response Time:** Reacts quickly to transient voltage spikes.  
- **High Surge Capability:** Handles large surge currents.  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Compact SMA Package:** Suitable for space-constrained applications.  

This information is strictly factual from Ic-phoenix technical data files. Let me know if you need further details.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB100CA --: Bidirectional TVS diode in SMB package with comparable 100V standoff and 600W peak pulse power, suitable drop-in replacement for 90V standoff SMAJ90CA.
  • SMBJ90CA --: Bidirectional 600W TVS diode in SMB package with 90V standoff, directly matching the electrical rating of SMAJ90CA.
  • 1SMB90CA --: Bidirectional 600W SMB TVS diode with 90V standoff voltage, equivalent surge protection performance to SMAJ90CA.
  • P6SMB90CA --: 600W bidirectional TVS with 90V standoff in SMB package, matching the SMAJ90CA's clamping behavior with extra power margin.
  • 1.5SMC90CA --: 1500W bidirectional TVS at 90V standoff in SMC package; suitable when higher surge capability is needed and board space allows.
  • P6SMB91CA --: Similar 91V bidirectional TVS in SMB package with comparable clamping voltage, suitable substitute when SMAJ90CA is unavailable.
