Description and Introduction

NPN Darlington With built-in avalanche diode The part **SDC04** is manufactured by **SANKEN**. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Manufacturer:** SANKEN  
- **Part Number:** SDC04  
- **Type:** Schottky Barrier Diode (SBD)  
- **Package:** TO-220AB (through-hole mounting)  
- **Configuration:** Dual common cathode  
- **Maximum Average Forward Current (IF(AV)):** 20A per diode (40A total)  
- **Peak Forward Surge Current (IFSM):** 300A (per diode)  
- **Reverse Voltage (VR):** 40V  
- **Forward Voltage (VF):** 0.55V (typical at 10A, 25°C)  
- **Reverse Leakage Current (IR):** 1mA (max at VR, 25°C)  
- **Operating Junction Temperature (Tj):** -55°C to +150°C  
- **Storage Temperature (Tstg):** -55°C to +150°C  

### **Descriptions:**  
- The **SDC04** is a high-efficiency Schottky Barrier Diode designed for power rectification applications.  
- It features a **dual common cathode** configuration, making it suitable for synchronous rectification in switching power supplies.  
- The diode offers **low forward voltage drop**, reducing power loss and improving efficiency.  
- It is housed in a **TO-220AB package**, providing good thermal performance for heat dissipation.  

### **Features:**  
- **Low forward voltage drop** for high efficiency.  
- **High current capability** (20A per diode, 40A total).  
- **Fast switching speed** due to Schottky barrier construction.  
- **High surge current tolerance** (300A per diode).  
- **Common cathode configuration** simplifies circuit design in rectification applications.  
- **Reliable operation** across a wide temperature range.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or additional parameters, refer to the official **SANKEN SDC04 datasheet**.

Application Scenarios & Design Considerations

NPN Darlington With built-in avalanche diode

Alternative Part Number

  • KBP206G --: Bridge rectifier with similar 600V/2A ratings, widely available and pin-compatible in many SDC04 applications.
  • DF06M --: 600V 1A bridge rectifier in DIP package, a common drop-in substitute for small bridge rectifiers like the SDC04.
  • MB6S --: 600V 0.5A surface-mount bridge rectifier, suitable when lower current is acceptable and a compact alternative is needed.
  • SDC-04 --: Same SDC series with hyphenated naming; identical function and ratings, drop-in replacement.
  • SDC04A --: Closest variant in the SDC family with equivalent electrical characteristics and footprint.
  • SDC-04A --: Hyphenated variant of the same series, functionally equivalent and commonly stocked as an alternative.
