Description and Introduction

N-Channel Power MOSFETs/ 27 A/ 60-100V The IRF543 is an N-channel power MOSFET manufactured by various semiconductor companies, including International Rectifier (now part of Infineon Technologies). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Drain-Source Voltage (VDSS):** 100V  
- **Continuous Drain Current (ID):** 17A (at 25°C)  
- **Pulsed Drain Current (IDM):** 68A  
- **Power Dissipation (PD):** 75W (at 25°C)  
- **Gate-Source Voltage (VGS):** ±20V  
- **On-Resistance (RDS(on)):** 0.11Ω (max at VGS = 10V)  
- **Threshold Voltage (VGS(th)):** 2-4V  
- **Input Capacitance (Ciss):** 700pF (typical)  
- **Output Capacitance (Coss):** 180pF (typical)  
- **Reverse Transfer Capacitance (Crss):** 50pF (typical)

- **Operating Temperature Range:** -55°C to +175°C  

### **Description:**  
The IRF543 is a power MOSFET designed for high-speed switching applications. It is commonly used in power supplies, motor control, DC-DC converters, and other high-efficiency circuits.  

### **Features:**  
- **High Voltage Capability:** Supports up to 100V drain-source voltage.  
- **Low On-Resistance:** Minimizes conduction losses.  
- **Fast Switching:** Suitable for high-frequency applications.  
- **Avalanche Energy Rated:** Provides robustness in inductive load conditions.  
- **TO-220 Package:** Ensures good thermal performance and ease of mounting.  

This information is based on standard datasheet specifications. For exact details, refer to the manufacturer's documentation.
