Up to 90% space saving over current SMD devices; AOI-capable
Nijmegen, June 23 2020: Nexperia, the expert in essential semiconductors, today announced the industry’s widest portfolio of automotive-qualified discretes in space-saving, thermally-efficient, AOI-compatible DFN (Discrete Flat No leads) packages. The AEC-Q101 range of devices available cuts across all Nexperia’s product groups and includes switching, Schottky, Zener and protection diodes, bipolar junction transistors (BJTs), N- and P-channel MOSFETs, resistor-equipped transistors and LED drivers.
Automotive qualified discrete leadless packages offered by Nexperia range from the very small form factor DFN1006BD-2 (1 x 0.6 x 0.5 mm) up to DFN2020D-3 (2 x 2 x 0.65 mm), including the recently-released DFN1110D-3 and DFN1412D-3 styles. DFN devices can measure as small as 0.6 mm2 offering a PCB space-saving of up to 90 % when compared to current SOT23 devices. The excellent thermal performance (Rth(j-sp)) allows an equal or better Ptot on the smaller DFN footprint. At the same time these packages stay cooler and improve overall system reliability. The Nexperia DFN package technology supports a Tj capability of up to 175°C.
Because automated optical inspection (AOI) is vital for some applications – especially automotive – Nexperia pioneered the development of side-wettable flanks (SWF) for the DFN package in 2010 and devices with SWF are now a proven, accepted solution. This enables visible solder joints to be inspected post soldering. An additional benefit of DFN packages with SWF comes from the mechanical robustness of the bond to the PCB, which is better than devices without side-wettable flanks. SWF improve shear forces and board bending capabilities.
Mark Roeloffzen, Vice President & General Manager of Nexperia’s Bipolar Discretes Business Group comments: “With the automotive DFN package family Nexperia gives engineers the choice: either to develop their application with current leaded SMD packages or in the space saving DFN technology. We are dedicated to lead the market with package innovation serving customer needs and offering the broadest discrete portfolio in DFN technology.”
A large number of discrete semiconductors in DFN packages is already in volume production, and Nexperia will release many more throughout 2020, resulting in the industry’s widest portfolio of such devices. Types available include standard, high-runner products such as BC847, BC817 and BAV99, plus many more.
