Description and Introduction

HIGH EFFICIENCY ULTRAFAST DIODE The **STTH102A** is a high-efficiency ultrafast diode manufactured by **STMicroelectronics**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** Ultrafast Diode  
- **Voltage Rating (V_RRM):** 200 V  
- **Average Forward Current (I_F(AV)):** 1 A  
- **Peak Forward Surge Current (I_FSM):** 30 A (non-repetitive)  
- **Forward Voltage Drop (V_F):** 1.3 V (typical at 1 A)  
- **Reverse Recovery Time (t_rr):** 35 ns (typical)  
- **Operating Junction Temperature (T_J):** -40°C to +150°C  

### **Description:**
- The **STTH102A** is designed for high-speed switching applications, offering low reverse recovery time and low forward voltage drop.  
- It is suitable for use in **power supplies, inverters, and freewheeling diodes** in switching circuits.  

### **Features:**
- **Ultrafast recovery time** for improved efficiency.  
- **Low switching losses** for high-frequency applications.  
- **High surge current capability** for robustness.  
- **AEC-Q101 qualified** for automotive applications.  
- **Pb-free and RoHS compliant** for environmental safety.  

The diode is available in **DO-41** package.
