Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The **SMAJ78CA** is a transient voltage suppressor (TVS) 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:** 400W (8/20µs waveform)  
- **Breakdown Voltage (VBR):** 87.3V (min), 96.7V (max)  
- **Standoff Voltage (VRWM):** 78V  
- **Clamping Voltage (VC):** 125V at 1A  
- **Maximum Reverse Leakage Current (IR):** 1µA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration allows clamping of both positive and negative voltage spikes.  
- Suitable for high-speed data line and power supply protection.  

### **Features:**
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (pico-second range).  
- **High Surge Capability:** Handles high transient energy.  
- **RoHS Compliant:** Meets environmental standards.  
- **Reliable Performance:** Robust construction for industrial applications.  

This information is strictly factual from the provided knowledge base. Let me know if you need further details.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ78CA --: Same 78V bidirectional TVS in a larger SMB package with higher surge rating; widely available and electrically compatible for most clamping needs.
  • P6SMB78CA --: Bidirectional 78V TVS diode in SMB package offering comparable standoff voltage and clamping performance as a robust cross-reference.
  • 1.5SMC78CA --: 1500W bidirectional TVS with 78V standoff in SMC package; higher power handling provides margin while matching the working voltage.
