Description and Introduction

PNP Epitaxial Silicon Transistor The TIP42CTU is a PNP power transistor manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Transistor Type:** PNP  
- **Collector-Emitter Voltage (VCE):** -100V  
- **Collector-Base Voltage (VCB):** -100V  
- **Emitter-Base Voltage (VEB):** -5V  
- **Collector Current (IC):** -6A (continuous)  
- **Power Dissipation (PD):** 65W (at 25°C)  
- **DC Current Gain (hFE):** 15-75 (at IC = -3A, VCE = -4V)  
- **Operating Junction Temperature (TJ):** -65°C to +150°C  
- **Storage Temperature Range:** -65°C to +150°C  

### **Descriptions:**  
- The TIP42CTU is a complementary PNP transistor to the TIP41CTU (NPN).  
- Designed for general-purpose amplifier and switching applications.  
- Comes in a TO-220AB package for efficient heat dissipation.  

### **Features:**  
- High current capability (-6A).  
- Low saturation voltage for improved efficiency.  
- Complementary pair available (TIP41CTU for NPN).  
- Suitable for power amplification and switching circuits.  

This information is based on Fairchild's datasheet for the TIP42CTU.

Application Scenarios & Design Considerations

PNP Epitaxial Silicon Transistor

Alternative Part Number

  • 2N6107 --: PNP power transistor rated 70V/8A in TO-220, close electrical match to TIP42C and widely available.
  • BD242C --: PNP power transistor 100V/3A in TO-220, suitable substitute for lower-current TIP42C applications.
  • MJE2955T --: PNP power transistor 60V/10A in TO-220, higher current capability and common TIP42C replacement.
