Toshiba XCEZ Automotive Zener Diodes
Toshiba XCEZ Automotive Zener Diodes feature 150mW and 300mW power dissipation and 200W peak pulse power. These diodes provide a typical voltage of VZ, which is accorded to the E24 series. The XCEZ zener diodes offer a lineup of 20 products with standard zener voltages ranging from 5.6V to 36V. These diodes also use Zener process to achieve lower dynamic resistance. The XCEZ zener diodes suppress system malfunctions caused by such noise, which can penetrate power supply lines and connectors of various automotive ECUs. These diodes are AEC-Q101 qualified and come in a SOD-523 (1.6mm x 0.8mm) package. Typical applications include automotive and voltage surge protection.
Small and highly compatible general-purpose package
The XCEZ diodes adopted the highly compatible and small SOD-523 package (1.6mm x 0.8mm), which reduces the mounting area by approximately 59% compared to the SOD-323 package (2.5mm x 1.25mm) used existing XCUZ series. This contributes to the miniaturization of circuit boards.
Packaging and Internal Circuit
Low Dynamic Resistance
The Zener diodes provide a steep slope in ITLP-VTLP curve at the reverse-voltage (VR) end, achieving a lower dynamic resistance. This enables high absorption of surge voltage to prevent damage and malfunction of the system and enhances protection of devices and circuits.

Surge Protection for Long Pulse Durations
The XCEZ zener diodes achieve a high maximum allowable Zener surge power of 6W with a 10ms pulse width. These diodes enable protection of semiconductor devices against long pulse width conditions in the millisecond range, such as high switching surges and overvoltages close to DC.
