Description and Introduction

General Purpose Amplifier and Switching Applications The TIP42A is a PNP power transistor manufactured by Motorola (MOT). Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **Motorola (MOT)**  

### **Specifications:**  
- **Transistor Type:** PNP  
- **Collector-Emitter Voltage (VCEO):** -40V  
- **Collector-Base Voltage (VCBO):** -40V  
- **Emitter-Base Voltage (VEBO):** -5V  
- **Collector Current (IC):** -6A (continuous)  
- **Power Dissipation (PD):** 65W (at 25°C case temperature)  
- **DC Current Gain (hFE):** 15 to 75 (at IC = -3A, VCE = -4V)  
- **Operating Junction Temperature (TJ):** -65°C to +150°C  
- **Storage Temperature Range (Tstg):** -65°C to +150°C  

### **Descriptions:**  
- The TIP42A is a complementary PNP transistor to the NPN TIP41A.  
- It is designed for general-purpose power amplification and switching applications.  
- The device is housed in a TO-220 package for efficient heat dissipation.  

### **Features:**  
- High current capability (-6A continuous collector current).  
- Low saturation voltage for improved efficiency.  
- Suitable for linear and switching applications.  
- Complementary pair available (TIP41A NPN).  
- Robust construction for reliable performance in power circuits.  

This information is based solely on the manufacturer's datasheet.

General Purpose Amplifier and Switching Applications

Alternative Part Number

  • MJE2955T --: PNP power transistor with comparable 60V/10A ratings and TO-220 package, widely available and a common substitute for TIP42A in linear and switching applications.
  • BD242A --: PNP power transistor in TO-220 with similar voltage and current capability, same manufacturer family, suitable for general-purpose amplifier and switching use.
  • 2SA1943 --: High-power PNP transistor with higher current and voltage ratings than TIP42A, usable where extra margin is acceptable in audio and power switching circuits.
  • 2N6107 --: PNP power transistor with similar 60V/10A ratings and TO-220 package, widely available and a common substitute for TIP42A.
