Nexperia launches industry-first LED drivers in DFN package with side-wettable flanks


AEC-Q101-qualified DFN2020D-6 devices save up to 90% PCB space; side-wettable flanks enable automated inspection (AOI) and improve reliability

Nexperia announced a new range of LED drivers in the space-saving DFN2020D-6 (SOT1118D) package. This case style features side-wettable flanks (SWF) which facilitate the use of AOI (automated optical inspection), and improve reliability. This is the first time LED drivers have been available in this beneficial package. The new leadless devices join Nexperia’s wide range of LED drivers in leaded packages offering equivalent performance yet reducing PCB space by up to 90% compared to SOT223.

With a footprint of just 2×2 mm and a low profile of 0.65 mm, the new DFN2020D-6 LED drivers are available in NPN and PNP technology. They feature an output current of up to 250 mA (NCR32x types) and a maximum supply voltage of 75 V. Their high thermal power capability is at least equal to any other package for LED drivers.

The use of side-wettable flanks not only enables AOI techniques to be used – which is especially important for automotive customers – but also improves reliability. Devices with side-wettable flanks exhibit a greater resistance to shear forces, and can handle greater board flexing without cracking than devices without side-wettable flanks.

Four DFN2020D-6 LED drivers (NCR320PAS, NCR321PAS, NCR420PAS, and NCR421PAS) are in mass production now.
