Product details

650 V CoolMOS™ — what this N-channel switch brings to the BOM

Its 6.2 A continuous drain rating and 750 mOhm Rds(on) at 10 V gate drive put it in the low-to-mid current tier of the 600 V–650 V class — sized for auxiliary supplies and lower-power SMPS where conduction loss is secondary to switching loss.

Infineon lists the SPA06N60C3XKSA1 as Obsolete. No last-time-buy window remains open through the factory channel.

Gate charge and switching — what 31 nC means for the driver

The ±20 V max gate rating leaves margin for ringing on long gate traces, but a gate resistor in the 10 Ω–47 Ω range is still recommended to damp the LC tank formed by the PCB inductance and Ciss.

Package and mounting — TO-220 Full Pack

The PG-TO220-3-31 (Infineon's Full Pack variant) is a through-hole, fully isolated tab package. Mounting torque follows standard TO-220 practice; the 32 W dissipation assumes a heatsink with good thermal interface. The package is compatible with existing TO-220 clip or screw-mount hardware, so a board re-spin is not required when swapping from a non-isolated TO-220 if the hole pattern matches.

Frequently asked questions

What is the replacement for SPA06N60C3XKSA1?

Infineon does not list a direct pin-compatible successor for the SPA06N60C3XKSA1. For new designs, consider active CoolMOS C3 or C7 series parts in the same TO-220 Full Pack package, but verify gate-drive voltage, Rds(on), and thermal specs against your layout — no drop-in substitute is guaranteed without checking the datasheet.
