Description and Introduction

Through-Hole Schottky Rectifiers The MBR1550CT is a Schottky rectifier manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** Dual Schottky Rectifier  
- **Voltage Rating (V_RRM):** 50V  
- **Average Forward Current (I_F(AV)):** 15A (per diode)  
- **Peak Forward Surge Current (I_FSM):** 150A  
- **Forward Voltage Drop (V_F):** 0.85V (typical) at 7.5A  
- **Reverse Leakage Current (I_R):** 0.5mA (typical) at 50V  
- **Junction Temperature Range (T_J):** -65°C to +150°C  
- **Package:** TO-220AB (3-pin)  

### **Descriptions:**
- The MBR1550CT consists of two Schottky barrier diodes in a common cathode configuration.  
- Designed for high-efficiency rectification in power supplies, converters, and reverse polarity protection.  
- Low forward voltage drop reduces power loss and improves efficiency.  
- Fast switching capability with minimal reverse recovery time.  

### **Features:**
- **High Current Capability:** Supports up to 15A per diode.  
- **Low Power Loss:** Schottky technology ensures minimal heat dissipation.  
- **High Surge Current Capacity:** Withstands 150A peak surge current.  
- **Common Cathode Configuration:** Suitable for compact circuit designs.  
- **Pb-Free and RoHS Compliant:** Environmentally friendly.  

This rectifier is commonly used in switching power supplies, DC-DC converters, and freewheeling diode applications.  

(Note: Fairchild Semiconductor was acquired by ON Semiconductor in 2016, and the product may now be listed under their branding.)

Application Scenarios & Design Considerations

Through-Hole Schottky Rectifiers

Alternative Part Number

  • STPS1545CT --: Dual common-cathode Schottky rectifier with 15A per leg and 45V rating, very close to the MBR1550CT's 15A/50V specification and pin-compatible in TO-220AB.
  • VS-15CTQ045 --: 15A dual Schottky rectifier in TO-220 with 45V reverse voltage, functionally equivalent to the MBR1550CT and widely available.
  • MBR1545CT --: Dual Schottky rectifier rated 15A per leg at 45V in TO-220AB, a direct functional substitute with slightly lower voltage margin than the 50V original.
  • SBL1550CT --: Same 15A 50V dual common-cathode Schottky rectifier in TO-220AB with comparable forward voltage and switching performance.
  • MBR1550 --: 15A 50V Schottky barrier rectifier with similar ratings and TO-220 package, widely available and electrically compatible.
  • STPS1550CT --: Dual 15A 50V Schottky rectifier in TO-220AB offering equivalent current, voltage, and low forward-drop characteristics.
