RTS Series Circuit Protection

SCHURTER's RTS is a particularly compact device for thermal protection. Due to their inherent self-reinforcing heat-producing behavior, power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, SCRs, etc. can overheat and lead to thermal runaway. The RTS is designed to protect against such overheating, 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. After the soldering process, the RTS is mechanically activated by depressing the top into place, arming the RTS to trip at +210°C. It can be performed manually or automatically in the case of several devices being activated at once. In contrast to devices using electrical activation, with an additional contact, the status of the RTS is clearly and immediately visible to the installer. The need for an additional contact is also eliminated.

The RTS sustains operating currents up to 100 A at rated voltages of up to 60 V_DC in a remarkably compact package measuring 6.6 mm x 8.8 mm in size. Customer-specific versions are available. Added features include integrated shunt or overcurrent protection, resulting in less space consumed on the printed circuit board.

The RTS meets the high-reliability requirements of AEC-Q200 and MIL-STD.
