The TO-220AB package is widely stocked across the spot market, but the date-code traceability and laser-etch consistency should be verified on any gray-market lot — the HEXFET series is a common target for re-marked stock.","metaTitle":"IRL3705NPBF HEXFET N-Ch MOSFET, 55V 89A TO-220AB","metaDescription":"IRL3705NPBF HEXFET N-Channel MOSFET, 55V Vdss, 89A Id, 10 mOhm Rds(on) at 46A.

The 10 mOhm Rds(on) keeps conduction losses low at high current, and the 98 nC gate charge is manageable for PWM frequencies up to several tens of kilohertz with an appropriate gate driver. The 175 °C junction rating gives headroom for the thermal cycling typical in motor-start and stall conditions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRL3705NPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRL3705NPBF when reusing this data.
