- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The **KST43MTF** is a high-performance 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 efficient signal amplification.  
- **Low saturation voltage** for improved switching performance.  
- **High transition frequency (fT)** for RF and high-speed applications.  
- **Small form factor (SOT-23)** ideal for modern electronics.  
- **RoHS compliant** for environmental safety.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to FAIRCHILD's official datasheet.
