Product details

950 mOhm Rds(on) and 14.1 nC Qg — conduction vs switching trade-off

The 950 mOhm on-resistance at 10 V gate drive is moderate for a 650 V device, keeping conduction losses manageable at the 3.9 A current rating. This combination makes the part a natural fit for medium-frequency flyback and PFC stages where the switching loss budget is tighter than the conduction loss budget.

DPAK (TO-252) — surface-mount assembly and thermal path

The DPAK (TO-252) package with two leads and a tab is a standard surface-mount footprint for medium-power MOSFETs.

Frequently asked questions

What is the closest functional equivalent to IPD65R950CFDATMA2?

The closest functional peer in the same family is the IPD50R950CEAUMA1 from the CoolMOS™ CE series. It shares the same 950 mOhm Rds(on) and DPAK package but is rated for 500 V Vdss instead of 650 V, with a slightly higher 4.3 A Id and a lower 10.5 nC Qg. The 650 V rating of the CFD2 part provides additional voltage headroom for designs with higher bus voltages or transient margins.

Is IPD65R950CFDATMA2 RoHS compliant?

Yes, the IPD65R950CFDATMA2 is ROHS3 compliant, meeting the restriction of hazardous substances directive including the four phthalates.
