Toshiba Electronics Europe GmbH has expanded its range of automotive-grade surge-protection Zener diodes with the introduction of the XCEZ series.
The new diodes are housed in a compact SOD-523 package, making them suitable for space-limited automotive systems such as in-vehicle infotainment (IVI), advanced driver-assistance systems (ADAS), and battery management systems (BMS) commonly used in electric vehicles (EVs).
As electrification increases the number and complexity of electronic control units (ECUs) in vehicles, effective protection against electrical noise and voltage surges has become essential. The XCEZ series is designed to suppress malfunctions caused by electrostatic discharge (ESD) and switching surges that can enter through power lines or connectors, helping to improve system reliability in EV architectures.
Each device leverages Toshiba’s proprietary Zener process to achieve low dynamic resistance, allowing it to absorb surge energy more efficiently and protect downstream circuits. The series is available in a wide range of Zener voltages from 5.6 V to 36 V and meets AEC-Q101 automotive reliability standards.
