Its 800 V drain-source rating (Vdss) gives the headroom needed in universal-input flyback converters, PFC boost stages, and auxiliary power supplies where the DC bus can exceed 400 V and transients push higher. The PG-TO220-FP full-pack package means the back of the part is fully molded — no exposed metal tab. That saves an insulating washer and simplifies assembly, but the thermal path runs through the epoxy, so the 31 W maximum power dissipation is lower than a standard TO-220 with the same die. ## Sizing the gate drive and switching losses The 10 V drive voltage (Vgs) is the recommended level to achieve the rated Rds(on); driving with 12 V is fine within the ±20 V Vgs max. ## Through-hole assembly and rework The TO-220 Full Pack is a three-lead through-hole package. It solders into a board with standard wave or hand-soldering; the full-mold body means no metal tab to solder to a copper pour. Rework is straightforward — heat all three leads simultaneously with a wide tip or hot air, lift the part without lifting the pad.","metaTitle":"Infineon IPA80R1K4CEXKSA1 CoolMOS CE N-Ch 800V 2.8A MOSFET","metaDescription":"Infineon IPA80R1K4CEXKSA1 N-channel 800V 2.8A MOSFET, CoolMOS CE series, 1.4 Ohm Rds(on), PG-TO220-FP package.

Both share the same CoolMOS CE die and electrical ratings. For a pin-compatible alternative within the family, any IPA80R device in the same PG-TO220-FP package will fit the same footprint, but check the Rds(on) and current rating against your design margin."},{"question":"Can IPA80R1K4CEXKSA1 be used in a flyback converter?","answer":"Yes. The 800 V drain-source rating provides adequate margin for universal-input AC-DC flyback converters (up to 400 V DC bus plus leakage inductance spike). The 2.8 A continuous drain current and 1.4 Ohm Rds(on) suit auxiliary supplies and lower-power (<50 W) flyback stages. The 23 nC gate charge keeps switching losses low at typical flyback frequencies."},{"question":"Is IPA80R1K4CEXKSA1 RoHS compliant?","answer":"Standard Infineon CoolMOS CE devices are RoHS compliant and halogen-free.
