Description and Introduction

NPN (AUDIO/ HIGH FREQUENCY AMPLIFIER/ OSC.) The KSC945 is a general-purpose NPN transistor manufactured by Fairchild Semiconductor (now part of ON Semiconductor).  

### **Specifications:**  
- **Type:** NPN Bipolar Junction Transistor (BJT)  
- **Collector-Base Voltage (VCBO):** 60V  
- **Collector-Emitter Voltage (VCEO):** 50V  
- **Emitter-Base Voltage (VEBO):** 5V  
- **Collector Current (IC):** 150mA  
- **Power Dissipation (PD):** 400mW  
- **DC Current Gain (hFE):** 60 to 320 (depending on grade)  
- **Transition Frequency (fT):** 150MHz  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The KSC945 is a low-power, high-gain NPN transistor designed for general-purpose amplification and switching applications. It is commonly used in audio amplifiers, signal processing, and driver circuits.  

### **Features:**  
- High current gain (hFE)  
- Low noise performance  
- Suitable for small-signal amplification  
- TO-92 package for easy mounting  

This transistor is a complementary part to the KSA733 (PNP transistor).
