Product details

22 nC gate charge — switching loss budget

The low Qg also supports switching frequencies above 100 kHz in resonant or quasi-resonant topologies, where gate-drive losses would otherwise dominate.

This makes the part suitable for outdoor telecom rectifiers, motor drives in unheated enclosures, and under-hood automotive auxiliary converters (though it is not AEC-Q101 qualified).

The part remains available for existing production but is not targeted for new design-ins. Infineon typically phases out NRND parts over a multi-year window, but the supply channel is already tightening.

Frequently asked questions

Is IPA60R385CPXKSA1 obsolete or NRND?

It is not fully discontinued, but Infineon advises against using it in new designs. Existing production can continue, but the part may become harder to source over time.

What is the Rds(on) of IPA60R385CPXKSA1?

The maximum on-resistance is 385 mOhm at 10 V gate drive with 5.2 A drain current. At lower gate voltages the Rds(on) increases significantly — the 3.5 V threshold at 340 µA is the turn-on point, not a logic-level drive rating.

What is the replacement for IPA60R385CPXKSA1?

Infineon does not list a single direct successor in the lifecycle record. For a new design, look at active CoolMOS CP or C7 series parts in the TO-220 Full Pack package with 600 V and 9 A–12 A ratings. Any substitute requires thermal and switching characterization in your circuit before committing the BOM.
