Features and Applications

The STBP120BVDK6F device provides overvoltage protection for input voltage up to +28 V. Its low RDS(on) N-channel MOSFET switch protects the systems connected to the OUT pin against failures of the DC power supplies in accordance with the China MII Communications Standard YD/T 1591-2006.

In the event of an input overvoltage condition, the device immediately disconnects the DC power supply by turning off an internal low RDS(on) N-channel MOSFET to prevent damage to protected systems.The STBP120 is offered in a small, RoHS-compliant TDFN – 10-lead (2.5 mm x 2 mm) package.


  • Input overvoltage protection up to 28 V

  • Low RDS(on) of 90 mΩ
  • Integrated charge pump
  • Thermal shutdown protection
  • Softstart feature to control the inrush current
  • Enable input (EN)
  • Fault indication output (FLT)
  • IN input ESD withstand voltage up to ±15 kV (air discharge), up to ±8 kV (contact discharge) in typical application circuit with 1μF input capacitor (±2 kV HBM for standalone device)
  • Certain overvoltage options compliant with the China Communications Standard YD/T 1591-
    2006 (overvoltage protection only)
  • Small, RoHS compliant 2.5 x 2 mm TDFN – 10-lead package.


  • Smart phones
  • Digital cameras
  • PDA and palmtop devices
  • MP3 players
