Description and Introduction

SCHOTTKY BARRIER TYPE DIODE (SWITCHING TYPE POWER SUPPLY) The part **SMAB33** is manufactured by **KEC (Korea Electronics Corporation)**.  

### **Specifications:**  
- **Type:** Schottky Barrier Diode  
- **Package:** SOD-123  
- **Maximum Reverse Voltage (VR):** 30V  
- **Average Forward Current (IF):** 0.2A  
- **Peak Forward Surge Current (IFSM):** 1A  
- **Forward Voltage (VF):** 0.38V (at 0.1A)  
- **Reverse Leakage Current (IR):** 0.5µA (at VR = 30V)  
- **Operating Temperature Range:** -55°C to +125°C  

### **Descriptions and Features:**  
- **Low forward voltage drop** for improved efficiency.  
- **High switching speed** due to Schottky barrier construction.  
- **Small SOD-123 package** suitable for space-constrained applications.  
- **High reliability** with low leakage current.  
- **RoHS compliant**, ensuring environmental safety.  

This diode is commonly used in **power rectification, voltage clamping, and switching applications**.

Application Scenarios & Design Considerations

SCHOTTKY BARRIER TYPE DIODE (SWITCHING TYPE POWER SUPPLY)

Alternative Part Number

  • SMAJ33A --: Same SMA package unidirectional TVS diode with 33V standoff voltage; widely available and electrically equivalent.
  • P4SMA33A --: SMA-packaged 400W TVS diode with 33V standoff, matching the original's surge rating and form factor.
  • SMBJ33A --: SMB package TVS diode with 33V standoff; slightly larger package but higher surge capability and a common drop-in substitute.
