- **Operating Junction Temperature (TJ):** -65°C to +150°C  
- **Storage Temperature Range (TSTG):** -65°C to +150°C  

### **Description:**  
The TIP42B is a medium-power PNP transistor designed for general-purpose amplification and switching applications. It is commonly used in power supply circuits, audio amplifiers, and motor control systems.  

### **Features:**  
- High current capability (up to -6A continuous)  
- Low saturation voltage  
- Complementary to NPN TIP41B  
- TO-220 package for easy mounting and heat dissipation  

This information is based on the manufacturer's datasheet. For exact performance characteristics, refer to PECOR's official documentation.
