Description and Introduction

NPN Epitaxial Silicon Darlington Transistor The TIP142TTU is a power transistor manufactured by **FAIRCHILD** (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Type:** NPN Darlington Transistor  
- **Collector-Emitter Voltage (VCE):** 100V  
- **Collector Current (IC):** 10A (continuous)  
- **Peak Collector Current (ICM):** 15A  
- **Power Dissipation (PD):** 125W  
- **DC Current Gain (hFE):** 1000 (min) at 5A  
- **Package:** TO-220 (TIP142TTU variant)  

### **Descriptions:**  
- Designed for high-current switching and amplification applications.  
- Features a Darlington pair configuration for high gain.  
- Suitable for motor control, power supplies, and general-purpose amplification.  

### **Features:**  
- **High Current Capability:** Supports up to 10A continuous collector current.  
- **High Voltage Rating:** 100V collector-emitter breakdown voltage.  
- **Built-in Freewheeling Diode:** Enhances switching performance in inductive loads.  
- **Low Saturation Voltage:** Improves efficiency in switching applications.  

This information is sourced from Fairchild Semiconductor (now ON Semiconductor) datasheets and product documentation.

Application Scenarios & Design Considerations

NPN Epitaxial Silicon Darlington Transistor

Alternative Part Number

  • BDX33C --: NPN Darlington transistor in TO-220 with similar 100V/10A ratings and high hFE, a common drop-in replacement for TIP142.
  • 2N6045 --: NPN Darlington power transistor rated 100V/8A in TO-220, electrically close to TIP142 and widely available.
  • MJD127T4G --: NPN Darlington in DPAK with 100V/8A ratings; suitable alternative when a surface-mount package is acceptable.
  • MJD127 --: NPN Darlington in DPAK/TO-252 package with 100V/8A rating; suitable alternative when a surface-mount package is acceptable.
