The TO-220AB through-hole package suits point-of-load regulators, battery isolation, and inverter legs where board-level heatsinking is practical. For a BOM freeze, this part presents no last-time-buy risk.","metaTitle":"IRFB7430PBF MOSFET, N-Ch 40V 195A TO-220, 1.3mOhm","metaDescription":"IRFB7430PBF N-channel MOSFET from Infineon HEXFET/StrongIRFET series. 40V Vdss, 195A Id, 1.3mOhm Rds(on) at 10V.

For a lower gate charge alternative at the same voltage and package class, look at Infineon's OptiMOS 40 V series; the trade-off is typically higher Rds(on) for lower Qg. No direct pin-compatible second source from another manufacturer is listed in the official cross-reference."},{"question":"What is the IRFB7430PBF gate charge and why does it matter?","answer":"The total gate charge is 460 nC at 10 V. This is a high figure that dictates a gate driver capable of sourcing several amps of peak current if you plan to switch above a few tens of kHz. For low-frequency or soft-switched designs, the conduction loss advantage of the 1.3 mOhm Rds(on) outweighs the drive burden."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRFB7430PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRFB7430PBF when reusing this data.
