Housed in a standard TO-220-3 through-hole package (PG-TO220-3-1), it delivers 40 W maximum power dissipation. Input capacitance measures 530 pF at 25 V drain-source, a moderate figure that keeps gate-drive losses manageable in hard-switching applications up to low hundreds of kHz. ## Gate drive and threshold — what to watch Maximum gate threshold voltage is 4 V at 1 mA drain current. Maximum gate-source voltage is ±20 V. No NRND or EOL notice applies.","metaTitle":"BUZ73AHXKSA1 SIPMOS N-Channel MOSFET, 200V 5.5A TO-220","metaDescription":"Infineon BUZ73AHXKSA1 N-channel power MOSFET, 200 Vdss, 5.5 A continuous drain, 600 mOhm Rds(on) at 10 V.

Within the same SIPMOS® 200 V N-channel family, parts share the same 5.5 A / 600 mOhm ratings but differ in package (e.g., D2PAK surface-mount variants). For a direct pin-compatible drop-in, stick with the BUZ73AHXKSA1 order code — no official cross-reference to a second-source MPN is recorded in this listing."},{"question":"Where can I download the BUZ73AHXKSA1 datasheet?","answer":"The Infineon datasheet for the BUZ73A series (including the BUZ73AHXKSA1) is available from the manufacturer's document portal.

The 'HXKSA1' suffix denotes the Infineon packaging code for this lead form and reel/tube configuration. Electrical ratings (200 V, 5.5 A, 600 mOhm) are identical across the BUZ73A family; the difference is package and shipping medium only."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BUZ73AHXKSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BUZ73AHXKSA1 when reusing this data.
