Description and Introduction

OLD PRODUCT: NOT SUITABLE FOR NEW DESIGN-IN The STP4NA40FI is a power MOSFET manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Drain-Source Voltage (VDSS):** 400V  
- **Continuous Drain Current (ID):** 4A  
- **Pulsed Drain Current (IDM):** 16A  
- **Power Dissipation (PD):** 50W  
- **Gate-Source Voltage (VGS):** ±30V  
- **On-Resistance (RDS(on)):** 1.5Ω (max) at VGS = 10V  
- **Threshold Voltage (VGS(th)):** 2V to 4V  
- **Input Capacitance (Ciss):** 150pF (typ)  
- **Output Capacitance (Coss):** 30pF (typ)  
- **Reverse Transfer Capacitance (Crss):** 10pF (typ)  
- **Turn-On Delay Time (td(on)):** 10ns (typ)  
- **Turn-Off Delay Time (td(off)):** 35ns (typ)  
- **Operating Junction Temperature (TJ):** -55°C to 150°C  

### **Description:**  
The STP4NA40FI is an N-channel power MOSFET designed for high-voltage, high-speed switching applications. It is optimized for low gate charge and low on-resistance, making it suitable for power supplies, motor control, and other switching circuits.  

### **Features:**  
- **High Voltage Capability (400V)**  
- **Low On-Resistance (RDS(on))**  
- **Fast Switching Speed**  
- **Improved dv/dt Capability**  
- **Avalanche Ruggedness**  
- **TO-220FP (Insulated) Package**  

This MOSFET is commonly used in applications such as switch-mode power supplies (SMPS), inverters, and electronic ballasts.
