Overview

The DFN is available in 3 formats.

The smallest being the UFDFPN5 (5 leads) with body size of 1.7x1.4 mm and body

thickness is 0.55 mm.

The consumer one UFDFPN8 (8 leads) with body size of 2.0x3.0 mm and body thickness is

0.55 mm.

The automotive one WFDFPN8 (8 leads) with body size of 2.0x3.0 mm and body thickness

is 0.75 mm.

UFDFPN8/WFDFPN8 comply with Jedec Outline MO-229.

The DFN family has been designed to fulfill the same quality levels and same reliability

performance as standard semiconductor plastic packages. As a consequence these DFN

can be considered as standard surface mount devices which are assembled on a printed

circuit board (PCB) without any special or additional process steps.

Only Lead-free RoHS / Halogen Free compliant DFN are available in mass production.
