Description and Introduction

Zener TVSs The SMCJ12CA is a transient voltage suppressor (TVS) diode manufactured by CCD. Here are the specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 12V  
- **Voltage - Breakdown (V_BR):** 13.3V (min)  
- **Voltage - Clamping (V_C):** 19.9V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- The SMCJ12CA is a bidirectional TVS diode designed to protect sensitive electronics from voltage transients and surges.  
- It is part of the SMCJ series, which offers high surge capability in a compact SMC package.  
- Bidirectional polarity means it can suppress both positive and negative voltage spikes.  

### **Features:**  
- **High Surge Capability:** Handles transient events effectively.  
- **Low Clamping Voltage:** Provides robust protection for sensitive circuits.  
- **Bidirectional Operation:** Protects against both positive and negative transients.  
- **RoHS Compliant:** Meets environmental standards.  
- **Fast Response Time:** Reacts quickly to transient events (typically in picoseconds).  

This information is strictly based on available specifications for the SMCJ12CA from CCD.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1SMC12CA --: Bidirectional 1500W TVS diode with the same 12V standoff voltage and SMC package, directly interchangeable.
  • P6SMB12CA --: Bidirectional TVS with matching 12V standoff and similar clamping performance, though rated at 600W so verify surge margin.
  • SMAJ12CA --: Bidirectional 400W TVS in SMA package with same 12V standoff; suitable only if lower surge rating is acceptable.
  • SMDJ12CA --: 3000W bidirectional TVS with 12V standoff in SMC form factor, offers higher surge rating and fits the same footprint.
  • 1SMC12CAT3G --: Bidirectional 1500W TVS diode in SMC package with 12V standoff voltage, directly equivalent to SMCJ12CA and widely available.
  • 5.0SMDJ12CA --: Bidirectional 5000W TVS in SMC package with 12V standoff, offering higher peak pulse power for robust protection in the same footprint.
  • 1.5SMC12CA --: Same 1500W bidirectional TVS class with 12V standoff voltage, widely available and electrically equivalent for clamping transient surges.
