Description and Introduction

Zener TVSs The SMCJ75CA is a transient voltage suppressor (TVS) diode manufactured by **Fairchild Semiconductor** (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 75V  
- **Voltage - Breakdown (V_BR):** 83.3V (Min)  
- **Voltage - Clamping (V_CL):** 121V at 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs waveform)  
- **Power - Peak Pulse (P_PP):** 1500W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Description:**  
The SMCJ75CA is a **bidirectional** TVS diode designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive load switching. It offers fast response times and high surge capability.  

### **Features:**  
- **Bidirectional protection** (clamps both positive and negative transients)  
- **Low clamping voltage** for improved circuit protection  
- **High surge capability** (1500W peak pulse power)  
- **RoHS compliant**  
- **Automotive and industrial applications**  

For exact performance data, refer to the **Fairchild/ON Semiconductor datasheet**.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC75CA --: Same 1500W bidirectional TVS with 75V standoff in the SMC package, direct functional equivalent from a different series.
  • P6SMB75CA --: Bidirectional 75V TVS diode offering similar clamping performance; smaller SMB package but widely used as a drop-in for SMCJ75CA in space-constrained designs.
  • SMAJ75CA --: Bidirectional 75V TVS in SMA package with comparable standoff and clamping voltage, suitable when lower peak pulse power is acceptable.
  • SMDJ75CA --: 3000W bidirectional TVS in SMC package with matching 75V standoff voltage, offering higher surge capability as a robust substitute.
