6 Variants


Description

  • Patented surface mount thermal fuse to protect against thermal runaway of power semiconductors such as: MOSFET's, IC's, IGBT's, Triac's, SCR's, etc.
  • Highest reliability thanks to complete galvanic Separation.

Unique Selling Proposition

  • Separates rated voltages up to 60 VDC
  • Reflow compatible through mechanical activation procedure
  • Galvanic separation happens inside the RTS housing
  • Space-saving thanks to integrated shunt

Applications

  • Wherever power transistors are used
  • Automotive: Cooling fan applications, ABS power steering, PTC heaters, HVAC, Glow plugs, Diesel fuel heaters
  • Industrial: Battery Protection, Power supplies, Lighting ballasts, H-Bridge circuits, Motor drivers

Other versions on request

Activation status

Deactivated:
Before reflow the activation button should not be manipulated with a force greater 5 newton.


Activated:
Activation after reflow is necessary for the tripping functionality of the RTS. This activation is done by mechanically pressing the activation button with max 50 newton.
