Description and Introduction

Leaded Power Transistor Darlington The TIP146 is a PNP Darlington transistor manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** PNP Darlington Transistor  
- **Collector-Emitter Voltage (VCE):** -80V  
- **Collector-Base Voltage (VCB):** -80V  
- **Emitter-Base Voltage (VEB):** -5V  
- **Collector Current (IC):** -10A (continuous)  
- **Peak Collector Current (ICM):** -15A  
- **Power Dissipation (Ptot):** 125W (at 25°C)  
- **DC Current Gain (hFE):** 1000 (min) at IC = -4A  
- **Operating Junction Temperature (Tj):** -65°C to +150°C  
- **Package:** TO-220 (isolated tab)  

### **Descriptions:**  
- The TIP146 is a high-power PNP Darlington transistor designed for general-purpose amplifier and low-speed switching applications.  
- It features a built-in base-emitter shunt resistor for improved performance and thermal stability.  
- The TO-220 package allows for efficient heat dissipation when mounted on a heatsink.  

### **Features:**  
- High DC current gain (hFE ≥ 1000)  
- Low saturation voltage  
- High collector current capability (-10A continuous)  
- Built-in base-emitter resistor for enhanced stability  
- Isolated mounting tab for simplified heatsink attachment  

The TIP146 is commonly used in power amplifiers, motor control circuits, and switching applications.
