Input capacitance sits at 4340 pF at 400 V drain-source, which sets the miller plateau duration and the dead-time budget in a half-bridge leg. ## Full-pack isolation — no extra insulator needed The TO-220 Full-Pack (PG-TO220-FP) moulds the entire tab in epoxy, so the backside is electrically isolated. That saves a sil-pad or mica washer when bolting to a heatsink. Infineon lists the IPA65R045C7XKSA1 as Active (current production). The CoolMOS C7 platform is mature and widely second-sourced in the sense that multiple distributors carry stock, but Infineon is the sole fab.","metaTitle":"IPA65R045C7XKSA1 CoolMOS C7 N-Ch 650V 18A MOSFET","metaDescription":"Infineon IPA65R045C7XKSA1 CoolMOS C7 N-channel MOSFET: 650V Vdss, 45mOhm Rds(on), 18A Id, TO-220 Full-Pack.

The XKSA1 suffix indicates a specific packing and reel configuration (Tube), not a different silicon. For a pin-compatible second source, look at the IPA65R060C7 (60 mOhm) if the conduction loss budget allows a slightly higher Rds(on)."},{"question":"Can IPA65R045C7XKSA1 be used in high-power SMPS designs?","answer":"Yes, the 650 V Vdss and 45 mOhm Rds(on) make it suitable for the primary switch in SMPS topologies up to several hundred watts — PFC boost, LLC resonant half-bridge, and flyback converters. The 18 A continuous drain rating at 25 °C case temperature gives headroom for peak currents. Just derate the 35 W power dissipation limit for the full-pack package when sizing the heatsink."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IPA65R045C7XKSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IPA65R045C7XKSA1 when reusing this data.
