SCHURTER’s new reflowable thermal switch (RTS) is designed for protecting power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, SCRs against overheating. These devices have an inherent self-reinforcing heat-producing behavior, that can lead to overheating. The new, compact RTS protects them by reliably interrupting the circuit precisely at a pre-defined temperature.
The RTS can be mounted using conventional reflow soldering techniques with temperature profiles up to 260 °C and these units are set to trip at 210°C.
Operating currents up to 100 A can be sustained at rated voltages of up to 60 VDC in a remarkably compact package measuring 6.6 x 8.8 mm in size. Customer-specific versions are available.
Added features include integrated shunt or overcurrent protection, resulting in less space on the PCB.
Furthermore, the RTS meets the high-reliability requirements of AEC-Q200 and MIL-STD.
Pricing for the RTS starts at $ 1.55 each in 100 piece quantities. Packaging is 100 pieces or 750 pieces in blister tape and 33 cm reel.
