### **Description:**  
The **KSH47TF** is an NPN bipolar transistor designed for general-purpose amplification and switching applications. It is housed in a TO-92 package, making it suitable for through-hole PCB mounting.  

### **Features:**  
- High voltage capability (up to 300V)  
- Medium current handling (500mA)  
- Suitable for low-power amplification and switching  
- Wide operating temperature range  

For exact performance characteristics, refer to the official **FAIRCHILD datasheet** for the KSH47TF.

Application Scenarios & Design Considerations

NPN Epitaxial Silicon Transistor

Alternative Part Number

  • MJD47T4G --: NPN power transistor in DPAK with similar voltage and current ratings, widely available and a common cross for KSH47-type parts.
  • 2SD1898 --: NPN medium-power transistor in a comparable surface-mount package, suitable as a functional substitute for general switching and amplifier use.
  • BD237 --: NPN power transistor with similar current and voltage capability; through-hole package, so it fits when board space and mounting allow.
  • TIP41C --: General-purpose NPN power transistor with higher voltage rating and adequate current, commonly used as a robust substitute.
