Description and Introduction

Lead Free Finish/Rohs Compliant (Note1) ("P"Suffix designates Compliant. See ordering information) Here are the factual details about part SK33B from Ic-phoenix technical data files:

### **Manufacturer Specifications:**
- **Manufacturer:** Fairchild Semiconductor (now part of ON Semiconductor)  
- **Type:** Schottky Barrier Diode  
- **Maximum Average Forward Current (IF(AV)):** 3A  
- **Peak Forward Surge Current (IFSM):** 80A (non-repetitive)  
- **Maximum Reverse Voltage (VR):** 30V  
- **Forward Voltage Drop (VF):** 0.45V (typical at 3A)  
- **Reverse Leakage Current (IR):** 0.5mA (maximum at 30V)  
- **Junction Temperature (TJ):** -65°C to +125°C  
- **Storage Temperature (TSTG):** -65°C to +150°C  

### **Descriptions:**
- The **SK33B** is a **Schottky diode** designed for high-efficiency rectification in power supplies, converters, and reverse polarity protection circuits.  
- It features a **low forward voltage drop** and **fast switching speed**, making it suitable for high-frequency applications.  
- The diode is housed in a **DO-201AD (DO-27) package** for easy mounting.  

### **Features:**
- **Low power loss** due to minimal forward voltage drop.  
- **High current capability** with a 3A continuous rating.  
- **Fast recovery time** for improved efficiency in switching applications.  
- **Guard-ring passivated junction** for reliability and surge protection.  
- **Pb-free and RoHS compliant** for environmental safety.
