| FFF Compatibility | Matches the exact 3-pin X2-DFN1006 footprint and gate/source/drain pin mapping.Both packages have identical 1.0mm x 0.6mm footprint dimensions, with the alternative being slightly lower in height (0.40mm vs 0.50mm).Meets or exceeds all critical electrical ratings, including a 30V Vdss, identical Vgs(th) of 0.95V, and matching 460 mOhm Rds(on) at 4.5V. | Matches the identical 1-Gate, 2-Source, 3-Drain pinout mapping and pad structure.Footprint dimensions are identical (1.0mm x 0.6mm) and the package height is a nearly identical 0.48mm.Maximum power dissipation is lower (350mW vs 470mW) due to different rating conditions, meaning it may run warmer in high-load applications. | ||
 AI Summary | DMN3730UFB-7 by Diodes Incorporated: N-Channel 30 V 750mA (Ta) 470mW (Ta) Surface Mount X1-DFN1006-3. | This is a direct, higher-performance sibling from the same manufacturer, offering a higher current rating and power dissipation in the same footprint. It is a drop-in replacement that requires no board redesign.
| This Nexperia part is a highly compatible second-source alternative that offers better switching performance and gate charge. It is fully pin-compatible but has a slightly lower power dissipation rating.
