Emerging and developing packaging
DFN package
Power DFN series
DFN3820A:
- Product technologies include standard, Schottky, Ultrafast Rectifiers and TVS
- Low-profile package - dimension 3.8 mm x 2.0 mm with typical height of 0.88 mm
- Offers an AOI-capable package with wettable flanks
- Oxide planar chip technology
- Maximum current rating up to 7 A, equivalent to larger package performance
- Double the performance compared to SMP package
- AEC-Q101 and Vishay Automotive Grade
Signal DFN series
DFN1006-2A and DFN1110-3A:
- Technologies include: ESD Protection diodes, Zener diodes, Schottky diodes & Switching diodes
- Only 10% PCB board space consumption compared with traditional SOD/T packages
- Better thermal/power performance than traditional SOD/T packages
- Soldering can be checked by standard visual inspection
- No X-ray inspection necessary to meet automotive AOI requirements
- AEC-Q101 qualified and and Vishay Automotive Grade
- Uses non solder mask defined (NSMD) solder lands
- Uses the right amount of solder paste for proper stand-off and solder meniscus

FlatPAK package
Standard Rectifiers and TVS, Two-in-One Solution:
- Two different technologies in one FlatPAK 5 x 6 package saves PCB space
- Automotive solution for standard rectiifier (600V, 3A) and TransZorb(R) TVS (200W, Vbr 27V)
TMBS Rectifiers and Fred Pt(r) Ultrafast Rectifiers:
- One package instead of two saves > 65% PCB space
- Increase power density and performance efficiency
- Low forward, low power losses
