Description and Introduction

Solid State Relay (SSR) 1FormA The part **LH1547AT1** is manufactured by **Vishay**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Solid State Relay (SSR)  
- **Configuration:** SPST-NO (Single Pole Single Throw - Normally Open)  
- **Output Type:** MOSFET  
- **Load Voltage Range:** Up to **350 V**  
- **Load Current:** **120 mA**  
- **On-State Resistance:** **35 Ω** (typical)  
- **Isolation Voltage:** **5300 Vrms**  
- **Input Control Type:** DC  
- **Input Voltage Range:** **1.2 V to 1.5 V** (for LED control)  
- **Input Current:** **5 mA** (typical)  
- **Switching Time:** **0.5 ms (turn-on), 0.1 ms (turn-off)**  
- **Operating Temperature Range:** **-40°C to +110°C**  
- **Package:** **SMD (Surface Mount), 6-Pin DIP**  

### **Descriptions:**  
- The **LH1547AT1** is a **high-voltage, optically isolated solid-state relay** designed for switching low-power AC/DC loads.  
- It uses an **infrared LED** for input control, providing **electrical isolation** between input and output.  
- The output consists of **MOSFET switches**, ensuring fast switching and low power dissipation.  

### **Features:**  
- **High-voltage isolation (5300 Vrms)**  
- **Low input control current (5 mA typical)**  
- **Fast switching speed**  
- **No moving parts, ensuring long life and reliability**  
- **Suitable for low-power signal switching**  
- **Compliant with RoHS standards**  

This information is based solely on the manufacturer's datasheet and technical documentation.
