Description and Introduction

NPN Epitaxial Silicon Transistor The KSH44H11TF is a PNP power transistor manufactured by Fairchild Semiconductor. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** PNP Bipolar Junction Transistor (BJT)  
- **Collector-Emitter Voltage (VCE):** -80V  
- **Collector-Base Voltage (VCB):** -100V  
- **Emitter-Base Voltage (VEB):** -5V  
- **Collector Current (IC):** -8A (continuous)  
- **Power Dissipation (PD):** 50W (at 25°C)  
- **DC Current Gain (hFE):** 40 to 160 (at IC = 4A, VCE = -4V)  
- **Operating Junction Temperature (TJ):** -65°C to +150°C  
- **Storage Temperature (Tstg):** -65°C to +150°C  

### **Description:**  
The KSH44H11TF is a high-voltage, high-current PNP transistor designed for power amplification and switching applications. It is housed in a TO-220F package, providing efficient thermal performance.  

### **Features:**  
- High current capability (-8A)  
- High voltage rating (-80V VCE)  
- Low saturation voltage for improved efficiency  
- Fast switching speed  
- TO-220F (fully insulated) package for better thermal dissipation  

This transistor is commonly used in power supply circuits, motor control, and general-purpose amplification/switching applications.  

(Note: Always refer to the official Fairchild datasheet for precise details and application guidelines.)

Application Scenarios & Design Considerations

NPN Epitaxial Silicon Transistor

Alternative Part Number

  • MJE243G --: NPN power transistor with similar 4A/80V ratings and TO-220 package, widely available and a common drop-in for general switching and amplifier use.
  • BD241C --: NPN power transistor rated 4A/100V in TO-220, offering higher voltage margin and similar gain characteristics for switching and linear applications.
  • TIP41C --: Popular NPN power transistor rated 6A/100V in TO-220, providing extra current headroom and broad availability as a functional substitute.
