Thermal Protection

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

	Reflow soldering pads

	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.
