Description and Introduction

5.0 AMPS. Surface Mount Schottky Barrier Rectifiers Here are the factual details about part SK54B manufacturer TSC specifications, descriptions, and features:  

### **Manufacturer:** TSC (Taiwan Semiconductor)  

### **Part Number:** SK54B  

### **Specifications:**  
- **Type:** Schottky Barrier Diode  
- **Maximum Average Forward Current (IF(AV)):** 5A  
- **Peak Forward Surge Current (IFSM):** 150A (non-repetitive)  
- **Maximum Reverse Voltage (VR):** 40V  
- **Forward Voltage Drop (VF):** 0.55V (typical at 5A)  
- **Reverse Leakage Current (IR):** 0.5mA (maximum at rated voltage)  
- **Operating Temperature Range:** -65°C to +125°C  
- **Junction Temperature (TJ):** 125°C  

### **Description:**  
The SK54B is a Schottky barrier diode designed for high-efficiency rectification in power supply applications. It features low forward voltage drop and fast switching characteristics, making it suitable for high-frequency circuits.  

### **Features:**  
- Low forward voltage drop for reduced power loss  
- High current capability  
- Fast switching speed  
- High temperature operation stability  
- Lead-free and RoHS compliant  

This information is based on the manufacturer's datasheet for the SK54B diode.

Application Scenarios & Design Considerations

5.0 AMPS. Surface Mount Schottky Barrier Rectifiers

Alternative Part Number

  • SS54 --: 5A 40V Schottky rectifier in SMA package, same ratings and footprint as SK54B, widely available and directly drop-in compatible.
  • MBR540 --: 5A 40V Schottky barrier rectifier with equivalent current and voltage ratings, suitable replacement in most SMA/SMB applications.
  • 1N5824 --: 5A 40V Schottky diode with comparable forward current and reverse voltage, usable as an alternative where axial package fits.
  • SK54 --: 5A 40V Schottky diode from a different series naming, same electrical characteristics and SMA footprint.
