- **Transition Frequency (fT):** 250MHz  

### **Description:**  
The **KSC3953-D-STU** is a high-speed switching 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 amplification.  
- Low saturation voltage for efficient switching.  
- High transition frequency (fT) for fast switching applications.  
- Compact SOT-23 package for surface-mount applications.  
- Suitable for low-power and high-frequency circuits.  

For exact application details, refer to the official datasheet from FAIRCHILD.
