Description and Introduction

Zener TVSs The SMCJ30CA is a transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 30V  
- **Voltage - Breakdown (V_BR):** 33.3V (min)  
- **Voltage - Clamping (V_C):** 48.4V at 24.2A  
- **Current - Peak Pulse (I_PP):** 24.2A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature:** -55°C to +150°C  
- **Package / Case:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ30CA is a bidirectional TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching.  
- It is part of the SMCJ series, which offers high surge capability in a compact SMC package.  

### **Features:**  
- **Bidirectional Protection:** Clamps both positive and negative transients.  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **High Surge Capability:** Withstands high peak pulse currents.  
- **RoHS Compliant:** Meets environmental standards.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1SMC30CA --: Same 1500W bidirectional TVS with 30V standoff voltage in the SMC package, widely available and electrically equivalent.
  • P6SMB30CA --: Bidirectional 600W TVS with matching 30V standoff; lower power rating but usable in less demanding clamping applications.
  • SMAJ30CA --: Bidirectional 400W TVS with the same 30V standoff voltage; smaller SMA package suits space-constrained designs with reduced surge capability.
  • 1.5SMC30CA --: Same 1500W bidirectional TVS class with 30V standoff voltage, directly interchangeable in most clamping applications.
  • TPSMB30CA --: Automotive-grade 600W bidirectional TVS, 30V standoff, SMB package, good alternative when AEC-Q101 qualification is desired.
