Circuit protectors and solid state relays keep vehicles running
The »power train electrification« megatrend drives fast-paced changes in the architecture of on-board electrical systems. Hybrid and electrical drive concepts have higher demands for circuit protection solutions and relays.
E-T-A specializes in this area, fulfils the requirements of the automotive standards ISO 16750 and IATF 16949 and develops solutions for the vehicles of tomorrow. Our solid state relays are a good example as are our 48V protection circuit protectors, which are already available. Together with our customers we also design hybrid switchgear for up to 1,000 V VDC.

MOSFET technology produces continuous quiescent current and can lead to a total battery discharge in “Always On” applications. E-T-A’s autoreset circuit protectors do not produce quiescent current, have only a minimal voltage drop during operation and are particularly attractive due to the ECU integration option via SMD reflow soldering.

Interface like the 12 V power outlet in a car are frequently protected by our circuit breakers to ensure reliable operation of peripheral devices.
Designing for the vehicles of the future
E-T-A fulfils the requirements of the automotive standards ISO 16750 and IATF 16949. Our solid state relays are a good example as are our 48V circuit protection products, which are already available. E-T-A engages with our customers to also design hybrid switchgear for up to 1,000 VDC.
A quiet ride with solid state relays
Our solid state relays switch silently so they can be installed in the passenger cabin and directly into the existing on-board electrical system. They fit directly into standard ISO Micro sockets and can replace mechanical relays in applications where they get too hot, consume too much power or fail prematurely due to excess mechanical strain.
