PhotoMOS Automotive for EV / HEV / PHEV

AEC-Q101 certified PhotoMOS relay for Electric Vehicle (EV), Hybrid Electric Vehicle (HEV), and Plug-on Hybrid Electric Vehicle (PHEV) Applications

PhotoMOS Automotive Relay

PhotoMOS Automotive, TOWARD provides AEC-Q101 certified automotive-grade semiconductor relay products with Photo D-MOSFET technology (PhotoDMOS).  A wide range of operating temperature from -40 to +125 degree C.  It is suitable for EV, HEV, and PHEV applications. Furthermore, it is also applicable to infrastructures, such as battery management Systems (BMS), motor control (MC), power conversion (PWC), and Charging-Discharging circuit.


The Automotive Electronics Council (AEC) was originally established by Chrysler, Ford, and GM for the purpose of establishing common part-qualification and quality system standards.  From its inception, the AEC has consisted of two Committees:  the Quality Systems Committee and the Component Technical Committee.
