Zener diodes portfolio extends battery time and saves PCB space

Nexperia announced a wide range of low current voltage regulator diodes. The 50µA Zener diode range is offered in three different SMD package options, in an ultra-small DFN package and AEC-Q101 qualified parts, offering the best in customer choice and flexibility. Specified at a low-test current (50μA), the efficient diodes are excellent for low bias and portable battery-powered devices in mobile, automitive, wearable and industrial applications.

“The DFN1006BD-2 packaged parts with side-wettable flanks (SWF) address the concerns of various sectors, such as size, performance and ruggedness, and match many diverse applications,” says Paula Stümer, product manager at Nexperia. “Covering a wide 1.8V to 75V range, we deliver the industry’s broadest 50μA Zener diode portfolio in DFN technology. However, parts are also available in leaded SMD styles, giving customers the flexibility of choice.”

With 40 new types per package option covering nominal working voltages from 1.8V to 75V, the range is obtainable in the ultra-low-profile surface-mountable SOT23 (BZX8450), SOD323 (BZX38450) and SOD523 packages (BZX58550) and leadless DFN1006BD-2 (BZX8850S) package. The Zeners provide a non-repetitive peak reverse power dissipation of ≤40W, total power dissipation ≤300mW and low dynamic resistance. They are also provided as Q-portfolio parts, meeting the AEC-Q101 and ISO/TS16949 automotive quality standards. As more non-automotive applications demand further quality-related services, such as PPAP and extended longevity, these Q-portfolio parts satisfy this need.

The DFN package with compact dimensions (1mm x 0.6mm x 0.47mm) is the correct choice for substituting bulky leaded packages on PCBs and can save up to 60% in space. It provides SWF, which assures the solder flows up the side of the chip when it is soldered onto the PCB. This technology enables AOI, meeting the automotive industry’s high safety, reliability and quality needs. The high P(tot) of the DFN-packaged Zeners also run cooler than leaded parts, therefore, enhancing system reliability.
