SMD thermal fuse for high currents
See below:
Approvals and Compliances
60 VDC · up to 100 A · 210 °C · PCB, SMT
Description
- Patented surface mount thermal fuse to protect against thermal runa-
way of power semiconductors such as: MOSFET's, IC's, IGBT's,
Triac's, SCR's, etc.
- Provides physical protection in cases where all software-based security
measures have failed
Unique Selling Proposition
- Separates rated voltages up to 60VDC
- Reflow compatible through mechanical activation procedure
- Galvanic separation happens inside the RTS housing
- Smallest footprint with just two contacts
Applications
- Wherever power transistors are used
- Automotive: Cooling fan applications, ABS power steering, PTC hea-
ters, HVAC, Glow plugs, Diesel fuel heaters
- Industrial: Battery Protection, Power supplies, Lighting ballasts, H-
Bridge circuits, Motor drivers
Other versions on request
- Thermal fuse with integrated shunt
