Product details

The SPA04N60C3XKSA1 is housed in a TO-220 Full Pack (PG-TO220-3-31), which electrically isolates the back of the tab from the drain.

Switching parameters that matter for the driver stage

Gate charge is 25 nC maximum at 10 V gate drive. Input capacitance is 490 pF at 25 V drain-source. This figure, combined with the gate charge, determines the switching energy and the driver's peak current requirement.

Infineon lists the SPA04N60C3XKSA1 as obsolete. No official successor is recorded in the product lifecycle data. Availability is limited to factory-original reels and loose-tube inventory from excess stock and end-of-life buybacks. Date-code spread and packaging condition vary by lot — each quote is evaluated against the specific procurement quantity and acceptable date-code window.

Frequently asked questions

Is SPA04N60C3XKSA1 obsolete?

Yes, Infineon has marked the SPA04N60C3XKSA1 as obsolete. Any procurement must go through the surplus market.

What package is SPA04N60C3XKSA1?

It comes in a TO-220-3 Full Pack (PG-TO220-3-31), a through-hole package with an electrically isolated back tab — no insulating washer needed for heatsinking.
