SCHURTER RTS Series Reflowable Thermal Switch

SCHURTER has introduced the new RTS reflowable thermal switch, a compact overtemperature protection device designed for the highest demands of protection in power semiconductors such as MOSFETs, ICs, IGBTs, Triacs, and SCRs. It can be mounted using conventional reflow soldering techniques with temperature profiles up to 260°C.

After having the RTS reflow soldered on a PCB, mechanical activation arms the RTS for tripping at 210 °C. This activation can be done manually or by fully automated means. In contrast to electrical activation, the RTS activation status is clearly and immediately visible to the installer. Furthermore, the third additional contact required for electrical activation is thereby eliminated.

The new type of overtemperature protection shines with the smallest dimensions and highest load capacity. Operating currents up to 100 A at rated voltages of up to 60 VDC can be handled by the RTS, which is just 6.6 x 8.8 mm in size. Customer-specific variants are available with an integrated shunt or an additional
overcurrent fuse.These further integrated functions are resulting in less space
consumed on the printed circuit board. The Reflowable Thermal Switch meets
the high reliability requirements of AEC-Q200 and MIL-STD.
