Schurter has a long tradition with circuit breakers. In addition to their thermal release (bimetal), the classic TA35 and TA36 are now optionally equipped with an additional magnetic module, which promises reliable protection within milliseconds in the event of very high overcurrent (short circuit). The new TA35 / TA36 circuit breakers now offer thermal and magnetic tripping for protection against overcurrent in accordance with IEC 60934 standard, with a wide range of design options and finely graduated rated currents.

Semtech Corporation announced the latest addition to its RClamp platform. The RClamp3371ZC exceeds industry immunity standards for electrostatic discharge (ESD) protection robustness while only presenting 250 femtofarads of maximum loading capacitance. Engineered as a low clamping, ultra-low capacitance transient voltage suppression (TVS) device, the RClamp3371ZC is an ideal solution for safeguarding high speed interfaces, such as USB Type-C, from common ESD threats.
