Reflowable thermal switch protects against thermal runaway

SCHURTER RTS series compact reflowable thermal switch protects  power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, SCRs, etc., which can overheat and lead to thermal runaway, due to their inherent self-reinforcing heat-producing behaviour. Devices protect against such overheating, reliably and precisely interrupting the circuit at a pre-defined temperature. Device can be mounted using conventional reflow soldering techniques with temperature profiles up to 260 °C. After the solder process, device is mechanically activated by depressing the top into place, arming the RTS to trip at 210 °C.
