Description and Introduction

General Purpose Amplifier and Switching Applications The TIP42C is a PNP power transistor manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Transistor Type:** PNP  
- **Maximum Collector-Emitter Voltage (VCE):** -100V  
- **Maximum Collector-Base Voltage (VCB):** -100V  
- **Maximum Emitter-Base Voltage (VEB):** -5V  
- **Continuous Collector Current (IC):** -6A  
- **Peak Collector Current (ICM):** -10A  
- **Power Dissipation (PD):** 65W (at 25°C)  
- **DC Current Gain (hFE):** 15 to 75 (at IC = -3A, VCE = -4V)  
- **Transition Frequency (fT):** 3MHz (typical)  
- **Operating Junction Temperature (TJ):** -65°C to +150°C  
- **Package Type:** TO-220  

### **Descriptions:**  
- The TIP42C is a complementary PNP transistor to the NPN TIP41C.  
- It is designed for general-purpose power amplification and switching applications.  
- Suitable for medium-power linear and switching circuits.  

### **Features:**  
- High current capability (-6A continuous collector current).  
- High voltage rating (-100V collector-emitter voltage).  
- Low saturation voltage for improved efficiency.  
- TO-220 package for easy mounting on heat sinks.  
- Complementary pair available (TIP41C for NPN).  

This information is based on Fairchild Semiconductor's datasheet for the TIP42C transistor.
