Description and Introduction

Zener TVSs The SMCJ43CA is a transient voltage suppressor (TVS) diode manufactured by **Microsemi** (now part of **Microchip Technology**). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 43V  
- **Voltage - Breakdown (V_BR):** 47.8V (min)  
- **Voltage - Clamping (V_C):** 69.4V at 45.5A (I_PP)  
- **Peak Pulse Current (I_PP):** 45.5A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 1500W (10/1000μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Description:**  
The **SMCJ43CA** is a **bidirectional TVS diode** designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive switching events. It offers low clamping voltage and fast response time.  

### **Features:**  
- **Bidirectional protection** (suitable for AC or DC lines)  
- **High surge capability** (1500W peak pulse power)  
- **Low leakage current**  
- **Fast response time** (typically <1ns)  
- **RoHS compliant**  
- **AEC-Q101 qualified** (for automotive applications)  

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

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC43CA --: Same 1500W bidirectional TVS class with 43V standoff, higher surge rating and widely available drop-in replacement.
  • P6SMB43CA --: 600W bidirectional TVS with matching 43V standoff voltage, suitable for lower-power clamping applications.
  • SMAJ43CA --: 400W bidirectional TVS in SMA package with 43V standoff, good for space-constrained designs needing similar clamping.
  • 1SMC43CA --: Same 1500W bidirectional TVS diode with 43V standoff voltage, directly interchangeable in most circuits.
  • SMDJ43CA --: Same manufacturer, 3000W bidirectional TVS with 43V standoff; higher surge rating makes it a robust drop-in upgrade.
