Description and Introduction

NPN Epitaxial Silicon Transistor The part **KST42MTF** is manufactured by **FAIRCHILD**. Below are the specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Manufacturer:** FAIRCHILD  
- **Part Number:** KST42MTF  
- **Type:** N-Channel MOSFET  
- **Voltage Rating (VDS):** 60V  
- **Current Rating (ID):** 42A  
- **Power Dissipation (PD):** 125W  
- **Gate-Source Voltage (VGS):** ±20V  
- **On-Resistance (RDS(on)):** 0.042Ω (max) at VGS = 10V  
- **Package Type:** TO-220F (Fully Molded)  

### **Descriptions:**  
The **KST42MTF** is a high-performance N-Channel MOSFET designed for power management applications. It offers low on-resistance and high current handling, making it suitable for switching and amplification in various electronic circuits.  

### **Features:**  
- Low **RDS(on)** for reduced conduction losses  
- High current capability (42A continuous)  
- Fast switching performance  
- Fully molded TO-220F package for improved thermal efficiency  
- Suitable for power supply, motor control, and DC-DC converter applications

Application Scenarios & Design Considerations

NPN Epitaxial Silicon Transistor

Alternative Part Number

  • MMBTA42 --: Same NPN high-voltage transistor type (300V, SOT-23) with equivalent electrical characteristics and widely available.
  • PMBTA42 --: Direct SOT-23 NPN high-voltage transistor equivalent to the KST42 series, suitable drop-in replacement.
  • 2N6517 --: High-voltage NPN transistor with comparable ratings, usable as an alternative though in TO-92 package.
