Description and Introduction

Schottky Barrier Rectifiers The SB550 is a Schottky barrier diode manufactured by **Panasonic Electronic Components (PEC)**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Schottky Barrier Diode  
- **Maximum Average Forward Current (IF(AV)):** 5A  
- **Peak Forward Surge Current (IFSM):** 150A  
- **Maximum Reverse Voltage (VR):** 50V  
- **Forward Voltage Drop (VF):** Typically 0.55V at 5A  
- **Reverse Leakage Current (IR):** Typically 0.5mA at 50V  
- **Operating Junction Temperature (TJ):** -55°C to +150°C  
- **Storage Temperature Range (TSTG):** -55°C to +150°C  

### **Descriptions:**  
- The SB550 is a **high-efficiency** Schottky diode designed for **low-loss, high-speed switching** applications.  
- It is commonly used in **power rectification, DC-DC converters, and reverse polarity protection circuits**.  
- The diode is housed in a **DO-201AD (DO-27) package**, ensuring good thermal performance.  

### **Features:**  
- **Low forward voltage drop** for reduced power loss.  
- **Fast switching speed** due to Schottky barrier construction.  
- **High surge current capability** for robust performance.  
- **Lead-free and RoHS compliant** for environmental safety.  

This information is based on the manufacturer's datasheet and product documentation. For detailed performance curves and application notes, refer to PEC's official specifications.

Application Scenarios & Design Considerations

Schottky Barrier Rectifiers

Alternative Part Number

  • SS55 --: 5A 50V Schottky rectifier in SMA package, same current and voltage ratings as SB550, widely available and pin-compatible.
  • MBR550 --: 5A 50V Schottky barrier rectifier with equivalent forward current and reverse voltage, common drop-in replacement in SMA/DO-214AC.
  • 1N5825 --: 5A 40V Schottky rectifier with similar current capability; slightly lower voltage rating but acceptable in many 50V-margin designs.
  • SR550 --: 5A 50V Schottky rectifier in DO-201AD with comparable forward drop and thermal behavior, directly interchangeable in most power supply and polarity protection circuits.
