Description and Introduction

NPN Epitaxial Silicon Transistor The part **KST4124** is a transistor manufactured by **FAIRCHILD**. Below are the specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Type:** NPN Bipolar Junction Transistor (BJT)  
- **Collector-Emitter Voltage (VCE):** 40V  
- **Collector-Base Voltage (VCB):** 60V  
- **Emitter-Base Voltage (VEB):** 6V  
- **Collector Current (IC):** 600mA  
- **Power Dissipation (PD):** 625mW  
- **DC Current Gain (hFE):** 100-300 (at IC = 150mA, VCE = 1V)  
- **Transition Frequency (fT):** 300MHz  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The **KST4124** is a general-purpose NPN transistor designed for amplification and switching applications. It is suitable for low-power circuits and high-frequency applications due to its high transition frequency.  

### **Features:**  
- High current gain (hFE)  
- Low saturation voltage  
- High-speed switching capability  
- Suitable for small-signal amplification  

This information is based on Fairchild Semiconductor's datasheet for the **KST4124** transistor.
