Toshiba Electronic Devices & Storage Corporation ("Toshiba") recently launched " TLX9150M ", an automotive photorelay with an output withstand voltage of 900V ( minimum), ideal for use in 400V car batteries. This new photorelay is available in a small SO12L-T package. Bulk shipments begin today.

Electric vehicles (EVs) are using higher capacity and higher voltage batteries to improve range and charging times, and battery management systems (BMS) to continuously monitor and manage batteries to maximize battery life and improve performance.

They also monitor the isolation between the battery and body to ensure safety. Galvanically isolated photorelays are used in BMSs that must handle high voltages.

Photorelays commonly used in battery systems must have a withstand voltage of approximately twice the system voltage; 400V systems require an output withstand voltage of more than 800V. TLX9150M has an output voltage of 900V and is suitable for 400V systems. It also uses a new SO12L-T package, which is 25% smaller than Toshiba's SO16L-T package.

This helps achieve miniaturization of battery cells and reduce costs. The pin spacing and pin layout are the same as SO16L-T, allowing for common circuit board graphics designs.

Toshiba Electronic Devices & Storage Corporation is a leading supplier of advanced semiconductor and storage solutions, leveraging more than half a century of experience and innovation to provide customers and business partners with superior discrete semiconductor, system LSI and HDD products.

The company's 19,400 employees around the world are committed to maximizing product value and promoting close collaboration with customers to jointly create value and open up new markets. The company looks forward to building and contributing to a better future for people around the world.
