Description and Introduction

Zener TVSs The SMCJ58CA is a transient voltage suppressor (TVS) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 58V  
- **Voltage - Breakdown (V_BR):** 64.4V (min)  
- **Voltage - Clamping (V_C):** 93.6V at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20μs waveform)  
- **Power - Peak Pulse (P_PPM):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ58CA is a bidirectional TVS diode designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  
- It is part of the SMCJ series, which offers high surge capability in a compact SMC package.  
- Bidirectional operation allows it to clamp both positive and negative voltage spikes.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection by limiting transient voltages to safe levels.  
- **High Surge Capability:** Can handle large transient currents (up to 10A).  
- **Fast Response Time:** Reacts quickly to transient events (typically in picoseconds).  
- **RoHS Compliant:** Meets environmental standards for lead-free manufacturing.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC58CA --: Same 1500W bidirectional TVS class with 58V standoff voltage, widely available and electrically equivalent for surge clamping.
  • P6SMB58CA --: 600W SMB bidirectional TVS with matching 58V standoff; lower power rating but suitable for many clamp applications with smaller footprint.
  • SMAJ58CA --: 400W SMA bidirectional TVS at 58V standoff, a compact alternative when lower surge capability is acceptable.
  • 1.5SMC62CA --: Same SMC (DO-214AB) package bidirectional TVS with a close standoff voltage (58 V vs 62 V) and higher peak pulse power, making it a strong drop-in choice.
  • P6SMB62CA --: Bidirectional TVS in SMB package with comparable clamping performance; slightly lower power rating but widely available and pin-compatible in most layouts.
  • 1SMC58CA --: Same 1500W bidirectional TVS with 58V standoff voltage in the SMC package, directly interchangeable.
  • SMDJ58CA --: Same manufacturer family, 3000W bidirectional TVS with 58V standoff in SMC, offers higher surge rating as an upgrade.
  • 5.0SMDJ58CA --: 5000W bidirectional TVS with 58V standoff in SMC package, offers higher peak pulse power for robust clamping protection.
