Description and Introduction

Zener TVSs The SMCJ22A is a transient voltage suppressor (TVS) diode manufactured by **FAIRCHILD**. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Peak Pulse Power (PPP):** 1500W (for 10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 24.4V (minimum) to 27.0V (maximum)  
- **Standoff Voltage (VRWM):** 22V  
- **Clamping Voltage (VC):** 35.5V (at IPP = 10A)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VRWM)  
- **Junction Capacitance (CJ):** 1000pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients, surges, and ESD events.  
- Bidirectional TVS diode for AC or DC circuits.  
- RoHS compliant and lead-free.  

### **Features:**  
- **High Surge Capability** – Handles high transient power.  
- **Low Clamping Voltage** – Provides effective protection for sensitive components.  
- **Fast Response Time** – Reacts quickly to transient events (sub-nanosecond).  
- **Bidirectional Operation** – Suitable for both positive and negative voltage swings.  
- **Reliable Performance** – Robust construction for industrial and automotive applications.  

This information is strictly factual from the available knowledge base.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1SMC22AT3G --: Same 1500W unidirectional TVS diode with 22V standoff voltage, directly interchangeable in most circuits.
  • P6SMB22A --: 600W SMB-packaged unidirectional TVS with 22V standoff; lower power rating but suitable for less demanding surge environments.
  • SMAJ22A --: 400W SMA-packaged unidirectional TVS with 22V standoff; smaller power rating, usable where lower surge capability is acceptable.
  • 1SMB22AT3G --: Same 22V standoff unidirectional TVS in SMB package with 600W peak pulse rating, direct functional equivalent from a major supplier.
  • SMBJ22A --: 600W SMB-packaged unidirectional TVS with 22V standoff voltage, widely available and commonly used as a drop-in replacement.
