Toshiba Releases Automotive Photorelay With Output Withstand Voltage Of 900V, Housed In A Small Package

KAWASAKI, Japan, Oct 24 (Bernama) -- Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TLX9150M,” an automotive photorelay[¹] with an output withstand voltage of 900V (min) that is highly suitable for application in 400V automotive batteries. The new photorelay is housed in a small SO12L-T package. Volume shipments start today.

Electric vehicles (EVs) are using ever higher capacity and higher voltage batteries to improve cruising range and charge time, and battery management systems (BMS) to constantly monitor and manage the battery to maximize life and performance. They also monitor the isolation between the battery and the vehicle body to ensure safety. In BMS that must handle high voltages, electrically isolated photorelays are used.
