Description and Introduction

Audio Frequency Amplifier & High Frequency OSC. The KSC945CY is a general-purpose NPN bipolar junction transistor (BJT) manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Transistor Type:** NPN  
- **Maximum Collector-Base Voltage (VCB):** 60V  
- **Maximum Collector-Emitter Voltage (VCE):** 50V  
- **Maximum Emitter-Base Voltage (VEB):** 5V  
- **Maximum Collector Current (IC):** 150mA  
- **Power Dissipation (PD):** 625mW  
- **DC Current Gain (hFE):** 60 to 320 (depending on operating conditions)  
- **Transition Frequency (fT):** 150MHz  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The KSC945CY is a low-power, high-gain NPN transistor designed for general-purpose amplification and switching applications. It is housed in a TO-92 package, making it suitable for compact circuit designs.

### **Features:**  
- High current gain (hFE)  
- Low noise performance  
- Fast switching speed  
- Suitable for audio and RF applications  
- Compliant with RoHS standards  

This transistor is commonly used in signal amplification, driver stages, and low-power switching circuits.

Alternative Part Number

  • 2SC945 --: The KSC945 is a Fairchild clone of the Toshiba 2SC945 NPN audio/small-signal transistor; the original Toshiba part is a direct functional equivalent with matching pinout and gain characteristics.
  • BC547 --: Widely available general-purpose NPN small-signal transistor with similar voltage and current ratings, suitable as a functional substitute in most low-power switching and amplifier circuits.
  • 2N3904 --: Industry-standard NPN small-signal transistor with comparable Vceo and Ic ratings; a common, easily sourced alternative for general-purpose amplification and switching applications.
