Description and Introduction

DUAL AC INPUT PHOTOTRANSISTOR SMALL OUTLINE SURFACE MOUNT OPTOCOUPLER The ILD256 is a high-speed optocoupler manufactured by **Infineon Technologies**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Isolation Voltage:** 5000 Vrms (min)  
- **Data Rate:** 1 MBd (typical)  
- **Input Current (IF):** 5 mA (typical)  
- **Output Voltage (VCE):** 35 V (max)  
- **Current Transfer Ratio (CTR):** 50% (min) at IF = 5 mA  
- **Propagation Delay (tPLH / tPHL):** 0.5 µs (max)  
- **Operating Temperature Range:** -40°C to +100°C  
- **Package Type:** DIP-6 (Dual Inline Package)  

### **Descriptions:**  
- The **ILD256** is a **phototransistor-based optocoupler** designed for high-speed digital signal isolation.  
- It provides **galvanic isolation** between input and output circuits, preventing ground loops and noise interference.  
- Suitable for **industrial, automotive, and communication applications** requiring reliable signal transmission.  

### **Features:**  
- **High-speed switching** (1 MBd data rate)  
- **Low input current requirement** (5 mA typical)  
- **High isolation voltage** (5000 Vrms)  
- **Wide operating temperature range** (-40°C to +100°C)  
- **Compact DIP-6 package** for easy PCB mounting  
- **Compliant with safety standards** (UL, CSA, VDE)  

This information is based solely on Infineon's official documentation for the **ILD256** optocoupler.
