Description and Introduction

HIGH VOLTAGE ULTRAFAST RECTIFIER The STTH310S is a high-efficiency ultrafast diode manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Type:** Ultrafast Diode  
- **Maximum Repetitive Reverse Voltage (VRRM):** 1000V  
- **Average Forward Current (IF(AV)):** 3A  
- **Peak Forward Surge Current (IFSM):** 100A (non-repetitive)  
- **Forward Voltage Drop (VF):** 1.7V (typical at IF = 3A)  
- **Reverse Recovery Time (trr):** 35ns (typical)  
- **Operating Junction Temperature (Tj):** -40°C to +175°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The STTH310S is designed for high-efficiency switching applications.  
- It features low forward voltage drop and ultrafast recovery time, making it suitable for high-frequency rectification.  
- The diode is optimized for use in power supplies, inverters, and other power management applications.  

### **Features:**  
- **Ultrafast Recovery:** Ensures minimal switching losses.  
- **Low Forward Voltage:** Enhances efficiency in power conversion.  
- **High Surge Current Capability:** Withstands transient overloads.  
- **High Junction Temperature:** Reliable operation in demanding environments.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  

This information is sourced from STMicroelectronics' official documentation.

Application Scenarios & Design Considerations

HIGH VOLTAGE ULTRAFAST RECTIFIER

Alternative Part Number

  • ES3D --: 3A 200V ultrafast recovery rectifier in SMA, same current/voltage class and fast switching as STTH310S, widely available.
  • US3D --: 3A 200V ultrafast rectifier in SMC/SMA package with comparable trr and forward drop, suitable drop-in replacement.
  • BYG23T --: 3A 200V ultrafast avalanche rectifier in SMA with similar recovery characteristics and ratings.
  • MBRS3100T3G --: 3A 100V Schottky rectifier in SMC package with similar forward voltage and current rating, widely available and drop-in compatible for most STTH310S applications.
  • SBR3U100LP-7 --: 3A 100V super barrier rectifier in PowerDI5 package offering low forward voltage and fast switching, suitable replacement for the ultrafast STTH310S.
  • V3P100-M3/86A --: 3A 100V Schottky barrier rectifier in SMPC package with comparable thermal and electrical characteristics, good alternative when SMC footprint is acceptable.
