Description and Introduction

N-CHANNEL 55V The STP140NF55 is an N-channel Power MOSFET manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Drain-Source Voltage (VDS):** 55V  
- **Continuous Drain Current (ID):** 140A  
- **Pulsed Drain Current (IDM):** 560A  
- **Power Dissipation (PD):** 300W  
- **Gate-Source Voltage (VGS):** ±20V  
- **On-Resistance (RDS(on)):** 3.5mΩ (max) at VGS = 10V  
- **Total Gate Charge (Qg):** 170nC (typ)  
- **Input Capacitance (Ciss):** 7200pF (typ)  
- **Operating Junction Temperature (TJ):** -55°C to +175°C  

### **Description:**
The STP140NF55 is designed for high-power switching applications, offering low on-resistance and high current capability. It is optimized for efficiency in power conversion systems, motor control, and other high-current applications.

### **Features:**
- **Low RDS(on):** Ensures minimal conduction losses.  
- **High Current Handling:** Supports up to 140A continuous current.  
- **Fast Switching:** Suitable for high-frequency applications.  
- **Avalanche Rated:** Robust against voltage spikes.  
- **TO-220 Package:** Provides good thermal performance.  
- **100% Avalanche Tested:** Ensures reliability under harsh conditions.  

This MOSFET is commonly used in power supplies, DC-DC converters, motor drives, and automotive applications.
