### **Description:**  
The TM861S is a high-voltage NPN bipolar power transistor designed for applications requiring high voltage switching and amplification. It is commonly used in power supply circuits, inverters, and motor control systems.  

### **Features:**  
- High collector-emitter voltage (800V)  
- Medium power handling capability (50W)  
- Fast switching performance  
- TO-3P package for efficient heat dissipation  
- Suitable for high-voltage industrial applications  

For exact performance characteristics, refer to the official SANKEN datasheet.

Application Scenarios & Design Considerations

Standard Triac

Alternative Part Number

  • LM317T --: Widely available adjustable linear regulator in TO-220, commonly used as a substitute for Sanken regulator ICs with similar function and pinout.
  • L78S05CV --: Fixed 5V linear regulator in TO-220 with robust current capability, suitable replacement when the application uses a fixed output rail.
  • MC7805CTG --: Industry-standard 5V regulator in TO-220, pin-compatible with many Sanken regulator parts and easy to source.
  • STR-A6052M --: Offline switching regulator IC in a different series with comparable function and package, commonly used as a substitute in power supply designs.
  • ICE3BR0665J --: Integrated power management IC with similar switching regulator role and pin-compatible footprint for many SMPS applications.
  • VIPER22A --: Widely available offline switcher IC offering similar functionality and easy sourcing as a cross-manufacturer alternative.
