Product details

With a total gate charge of 93 nC at 10 V, the gate-drive power requirement stays moderate — a driver delivering 1 A peak can switch this FET in the 50–100 kHz range without excessive cross-conduction.

Input capacitance Ciss is 4340 pF at 400 V drain bias. This is a typical figure for a 650 V FET in this Rds(on) bracket; the driver must supply the gate charge during the Miller region, not just the Ciss charging current.

Package and thermal path — TO-263-3 (D²Pak)

The part comes in a TO-263-3 (D²Pak) surface-mount package, supplier device code PG-TO263-3.

Frequently asked questions

Is IPB65R045C7ATMA2 lead-free and RoHS compliant?

Yes, the IPB65R045C7ATMA2 is RoHS3 compliant, which means it meets the EU RoHS directive without any exemptions. The part is lead-free and suitable for lead-free soldering processes.

What is the direct equivalent for IPB65R045C7ATMA2?

No direct pin-compatible equivalent is listed in the official cross-reference. The IPB65R045C7ATMA2 is a specific Rds(on) and current rating within the CoolMOS C7 family. For a lower-power alternative, the IPD50R950CEAUMA1 (CoolMOS CE, 500 V, 950 mOhm, 4.3 A) is a different voltage and current class and is not a functional replacement.

Is IPB65R045C7ATMA2 suitable for high-frequency switching applications?

Above that frequency, the gate-drive losses and switching losses may become significant — a gate-driver with 2 A or more peak current is recommended to keep the switching transitions fast.
