Description and Introduction

SMLJ Transient Voltage Suppressor Diode Series The part **SMLJ43CA** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **Microsemi**.  

### **Specifications:**  
- **Type:** Bidirectional TVS Diode  
- **Working Peak Reverse Voltage (V_RWM):** 36.8V  
- **Breakdown Voltage (V_BR):** 40.9V (min) to 45.2V (max)  
- **Clamping Voltage (V_C):** 58.1V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20μs waveform)  
- **Power Dissipation (P_PPM):** 600W (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed for **ESD and surge protection** in sensitive electronic circuits.  
- Provides **bidirectional clamping** for AC or DC lines.  
- Low leakage current for power-efficient applications.  

### **Features:**  
- **Fast response time** (nanosecond-level reaction to transients).  
- **High surge capability** for robust protection.  
- **RoHS compliant** (lead-free and environmentally friendly).  
- **AEC-Q101 qualified** for automotive applications.  

This information is based on Microsemi's datasheet for the **SMLJ43CA** TVS diode.
