Gate charge is 25 nC at 10 V. For a 100 kHz switching frequency the gate-drive current needed is about 2.5 mA average, well within a standard MOSFET driver's capability. The 6 V minimum drive voltage for the rated Rds(on) means a 5 V logic gate drive will not fully enhance the channel — budget a 10 V rail or a driver with bootstrap. ## Temperature range and package — industrial and automotive floor The 175°C maximum allows operation in high-ambient environments such as engine-bay electronics or sealed industrial enclosures without forced air, provided the thermal resistance from junction to case (RthJC) is managed with adequate heatsinking. It is ROHS3 compliant. No official second-source or pin-compatible cross-reference is listed in the Infineon OptiMOS™ 3 family for this specific Rds(on) tier.","metaTitle":"Infineon IPP139N08N3GXKSA1 OptiMOS 3 N-Channel MOSFET, 80 V","metaDescription":"Infineon IPP139N08N3GXKSA1 OptiMOS 3 N-channel power MOSFET. 80 Vdss, 45 A continuous drain, 13.9 mOhm Rds(on) at 10 V.

The IPP139N08N3GXKSA1 has a higher 80 V drain-source rating and a lower 13.9 mOhm Rds(on) at 10 V. A direct replacement depends on whether the 55 V rating of the IRFZ44N provides sufficient voltage margin for the application — it is not a pin-compatible substitute without a design review."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IPP139N08N3GXKSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IPP139N08N3GXKSA1 when reusing this data.
