Description and Introduction

Hight frequency secondary rectifier The **STTH2003C** is a high-voltage ultrafast diode manufactured by **STMicroelectronics (ST)**. Below are the specifications, descriptions, and features based on the available knowledge base:

### **Specifications:**  
- **Voltage Rating:**  
  - **Reverse Voltage (VRRM):** 200 V  
  - **Forward Voltage (VF):** 1.7 V (typical at 10 A)  
- **Current Rating:**  
  - **Average Forward Current (IF(AV)):** 20 A  
  - **Peak Forward Surge Current (IFSM):** 150 A (non-repetitive)  
- **Switching Characteristics:**  
  - **Reverse Recovery Time (trr):** 35 ns (typical)  
  - **Forward Recovery Time (tfr):** 500 ns (max)  
- **Thermal Characteristics:**  
  - **Junction-to-Case Thermal Resistance (RthJC):** 1.5 °C/W  
  - **Operating Junction Temperature (Tj):** -40 °C to +175 °C  

### **Description:**  
The **STTH2003C** is an ultrafast recovery diode designed for high-efficiency power conversion applications. It is optimized for high-frequency switching, making it suitable for use in power supplies, inverters, and motor control circuits. The diode features low reverse recovery time and low forward voltage drop, enhancing efficiency in high-power applications.

### **Features:**  
- **Ultrafast Recovery Time:** Ensures reduced switching losses.  
- **Low Forward Voltage Drop:** Improves efficiency in high-current applications.  
- **High Surge Current Capability:** Withstands high non-repetitive peak currents.  
- **High-Temperature Operation:** Reliable performance up to 175 °C junction temperature.  
- **AEC-Q101 Qualified:** Suitable for automotive applications (if applicable).  
- **TO-220AC Package:** Provides efficient thermal dissipation.  

This diode is commonly used in **SMPS (Switched-Mode Power Supplies), PFC (Power Factor Correction), and freewheeling/clamping circuits**.
