Infineon lists the IPA60R520CPXKSA1 as obsolete. The IPA60R380CP (600 V, 380 mOhm) is a higher-current variant in the same CoolMOS CP family and shares the same TO-220 Full Pack footprint, but its Rds(on) is lower, so the thermal and drive conditions differ — verify the gate drive and switching losses against your design before substituting. Pin-compatible across the CP series in the same package. ## What the 600 V rating and 520 mOhm mean for a flyback design The 600 V drain-source rating provides adequate margin for universal-input (85–265 VAC) flyback converters, where the reflected voltage plus leakage spike typically stays under 500 V. Gate drive should be a full 10 V to achieve the rated Rds(on); at lower drive voltages the on-resistance rises significantly. The ±20 V gate-source maximum gives headroom for ringing on the gate node in hard-switched circuits.","metaTitle":"Infineon IPA60R520CPXKSA1 CoolMOS N-Ch MOSFET, 600 V, 6.8 A","metaDescription":"Infineon IPA60R520CPXKSA1 CoolMOS N-channel MOSFET, 600 V drain-source, 520 mOhm Rds(on), 6.8 A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"CoolMOS™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"3.5V @ 250µA","Base Product Number":"IPA60R","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"520mOhm @ 3.8A, 10V","Power Dissipation (Max)":"30W (Tc)","Supplier Device Package":"PG-TO220-3-31","Gate Charge (Qg) (Max) @ Vgs":"31 nC @ 10 V","Drain to Source Voltage (Vdss)":"600 V","Input Capacitance (Ciss) (Max) @ Vds":"630 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"6.8A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for IPA60R520CPXKSA1?","answer":"Infineon has not published an official successor for the IPA60R520CPXKSA1.
