Description and Introduction

Zener TVSs The SMCJ26CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by **MICROSEMI**.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 26V  
- **Voltage - Breakdown (V_BR):** 28.9V (Min)  
- **Voltage - Clamping (V_C):** 41.4V at 16.5A  
- **Peak Pulse Current (I_PP):** 16.5A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed for **ESD and surge protection** in sensitive electronics.  
- **Bidirectional** polarity, allowing protection for both positive and negative transient voltages.  
- **Low leakage current** and **fast response time** (<1ns).  

### **Features:**  
- **High surge capability** for robust transient protection.  
- **RoHS compliant** and **halogen-free**.  
- **AEC-Q101 qualified** for automotive applications.  
- **IEC 61000-4-2 (ESD) compliant** (up to ±30kV).  
- **IEC 61000-4-4 (EFT) compliant** (up to 40A).  
- **IEC 61000-4-5 (Surge) compliant** (up to 16.5A).  

This diode is commonly used in **power supplies, communication equipment, automotive systems, and industrial electronics** for transient voltage suppression.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1SMC26CAT3G --: Bidirectional 1500W TVS diode with 26V standoff voltage, same SMC package and electrical characteristics as the original.
  • SMDJ26CA --: 3000W bidirectional TVS in SMC package with 26V standoff; higher surge rating provides margin while remaining form-factor compatible.
  • P6SMB26CA --: 600W bidirectional TVS with 26V standoff in SMB package; lower power rating but suitable for less demanding clamping applications.
  • 1.5SMC27CA --: Same SMC (DO-214AB) package bidirectional TVS with 1500W peak pulse power and a 27V standoff close to the 26V original, providing comparable clamping protection.
  • P6SMB27CA --: Bidirectional 600W TVS with a similar 27V standoff voltage; lower power rating but usable in less demanding clamping applications and widely available.
  • 1SMC26CA --: Same 1500W SMC-package bidirectional TVS with 26V standoff voltage; different series prefix makes it easy to distinguish from the source.
  • 5.0SMDJ26CA --: 5000W SMC bidirectional TVS at 26V standoff; a robust drop-in style alternative with a clearly different series designation.
