Toshiba adds Zener diodes in SOD-523 package
Toshiba Electronics Europe has expanded its automotive-grade surge-protection Zener diode lineup with the launch of the XCEZ series.
These new diodes are housed in a small and versatile SOD-523 package, making them particularly suitable for space-constrained applications such as in-vehicle Infotainment (IVI), advanced driver-assistance systems (ADAS) and battery management systems (BMS).
With the electrification in the automotive industry, there is a growing necessity for effective measures to prevent malfunctions caused by electrical noise. This includes protection against electrostatic discharge (ESD) in the nanosecond range and switching surges that can occur in the microsecond to millisecond range.
The XCEZ series is engineered to suppress system malfunctions stemming from electrostatic discharge (ESD) in the nanosecond range and switching surges that can occur in the microsecond to millisecond range.
The XCEZ series, like its predecessor, the XCUZ series, is built using Toshiba’s proprietary Zener process for low dynamic resistance. The XCEZ5V6 product features a dynamic resistance (RDYN) of just 0.16Ω (typ.).
According to Toshiba, the new products can provide surge protection for long pulse durations in the millisecond range, achieving a high maximum allowable Zener surge power of 6W with a 10ms pulse width, which safeguards semiconductor devices against high switching surges and overvoltages close to DC.
The XCEZ series offers a lineup of 20 products with standard Zener voltages ranging from 5.6V to 36V, making them suitable for major power supply lines. The series is AEC-Q101 compliant.
