Toshiba Electronic Devices & Storage Corporation has introduced the TLX9152M, a new automotive photorelay designed for high-voltage applications in electric vehicle (EV) battery systems. This advanced photorelay features an impressive output which can withstand a voltage of 900V, making it ideal for 400V battery management systems (BMS). Key features include its high isolation voltage of 5000 Vrms, an avalanche current rating of 0.6mA, and compliance with the AEC-Q101 and IEC 60664-1 International Standard. The TLX9152M is housed in an SO16L-T package, offering a reliable, normally open (1-Form-A) device solution for automotive applications.
For BMS handling high voltages, photorelays with robust electrical insulation are essential. Typically, these photorelays need to have an withstand voltage of approximately twice the system voltage. Toshiba's TLX9152M meets this requirement for 400V systems, thanks to its 900V output withstand voltage. This makes it a perfect fit for high-voltage battery monitoring, mechanical relay sticking detection, ground fault detection, and other critical functions within automotive BMS.
The TLX9152M is part of Toshiba's SO16L-T package lineup, which also includes the TLX9160T photorelay with a 1500V output withstand voltage. The use of this package allows for consistent circuit board design, making it easier for manufacturers to integrate the TLX9152M into existing systems.
