Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT ULTRA FAST RECTIFIER The US1B is a surface-mount rectifier diode manufactured by **FAIRCHILD Semiconductor**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Surface Mount Schottky Barrier Rectifier  
- **Package:** SOD-123  
- **Maximum Average Forward Current (Io):** 1A  
- **Peak Forward Surge Current (Ifsm):** 30A  
- **Maximum Reverse Voltage (Vr):** 100V  
- **Forward Voltage Drop (Vf):** 0.85V (typical) at 1A  
- **Reverse Leakage Current (Ir):** 100µA (max) at 100V  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The **US1B** is a high-efficiency Schottky diode designed for low-voltage, high-frequency applications such as switching power supplies, freewheeling diodes, and polarity protection. Its SOD-123 package makes it suitable for space-constrained PCB designs.  

### **Features:**  
- **Low Forward Voltage Drop** for improved efficiency.  
- **High Surge Current Capability** (30A).  
- **Fast Switching Speed** for high-frequency applications.  
- **Lead-Free & RoHS Compliant** for environmental safety.  
- **Surface-Mount Design** (SOD-123) for compact PCB layouts.  

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