Description and Introduction

NPN Epitaxial Silicon Transistor The KSC945YBU is a general-purpose NPN bipolar junction transistor (BJT) manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Transistor Type:** NPN  
- **Collector-Base Voltage (VCBO):** 60V  
- **Collector-Emitter Voltage (VCEO):** 50V  
- **Emitter-Base Voltage (VEBO):** 5V  
- **Collector Current (IC):** 150mA  
- **Power Dissipation (PD):** 625mW  
- **DC Current Gain (hFE):** 60-320 (varies by grade)  
- **Transition Frequency (fT):** 150MHz (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SOT-23 (Surface Mount)  

### **Description:**  
The KSC945YBU is a small-signal NPN transistor designed for general-purpose amplification and switching applications. It is housed in a compact SOT-23 package, making it suitable for space-constrained PCB designs.  

### **Features:**  
- High current gain (hFE) for improved signal amplification  
- Low noise performance  
- High transition frequency (fT) for RF and high-speed applications  
- Suitable for low-power switching and amplification  
- RoHS compliant  

This transistor is commonly used in audio amplifiers, signal processing, and switching circuits.
