Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The **SMAJ43A** 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 (V₃₀):** **43V**  
- **Voltage - Breakdown (Min):** **47.8V**  
- **Voltage - Clamping (Max) @ Iₚₚ:** **69.4V** (at **10A** peak pulse current)  
- **Peak Pulse Current (Iₚₚ):** **10A** (8/20µs waveform)  
- **Power - Peak Pulse:** **600W**  
- **Operating Temperature Range:** **-55°C to +150°C**  
- **Package / Case:** **DO-214AC (SMA)**  
- **Polarity:** **Unidirectional**  

### **Descriptions:**
- Designed for **transient overvoltage protection** in electronic circuits.  
- Provides **ESD (Electrostatic Discharge) and surge protection** for sensitive components.  
- Suitable for **high-speed data lines, power supplies, and communication interfaces**.  

### **Features:**
- **Low Clamping Voltage** for effective protection.  
- **Fast Response Time** (typically <1ps).  
- **High Surge Capability** (up to **10A** peak pulse).  
- **RoHS Compliant** (lead-free and environmentally friendly).  
- **Unidirectional Configuration** (protects against positive transients).  

This diode is commonly used in **automotive, industrial, and telecommunications applications** where transient voltage suppression is critical.
