Nexperia has introduced a series of low current Zener diodes. The 50µA Zener diode range is available in three different SMD package options, in an ultra-small DFN package and AEC-Q101 qualified part, providing the best customer choice and flexibility. Specified at low test currents (50µA), high efficiency diodes are excellent for low bias and portable battery powered equipment in mobile, automotive, wearable and industrial applications.
"The DFN1006BD-2 package's SWF addresses a variety of areas such as size, performance and ruggedness and matches many different applications," said Paula Stumer, Nexperia Product Manager. "In DFN technology, we offer the widest portfolio of 50μA Zener diodes in the industry, covering the 1.8V to 75V range. However, lead SMD style parts are also available, giving customers the flexibility to choose from."
40 new types of each package options cover the nominal operating voltage from 1.8V to 75V. SOT23 (bzx8450), sod323 (bzx38450) and sod523 packages (bzx58550) and lead-free dfn1006bd-2 (bzx8850s) can be installed on the ultra-low profile surface. The zener device has non repetitive peak reverse power consumption ≤ 40W, total power consumption ≤ 300MW and low dynamic resistance. Comply with aec-q101 and ISO / TS16949 automobile quality standards. As more non automotive applications require more quality related services, such as PPAP and extended life, these Q combined components meet this demand.
The compact size of DFN package (1mm x 0.6mm x 0.47mm) is the right choice to replace the bulky lead package on PCB, which can save up to 60% space. It provides swf to ensure that the solder flows to one side of the chip when welded to the PCB. This technology makes AOI possible and meets the needs of the automotive industry for high safety, reliability and quality. The high P (TOT) operating temperature of DFN encapsulated Zener tube is also lower than that of lead containing parts. Therefore, the reliability of the system is improved.
