At full rated current, the I²R loss at 25°C junction is under 45 W, which the 190 W maximum power dissipation rating can handle with an appropriate heatsink. ## Gate charge and drive requirements Total gate charge is 110 nC at 10 V gate drive. ## Package and thermal management The -55°C to 175°C junction temperature range covers military and industrial environments — avionics, downhole instrumentation, and engine-bay electronics are all within the operating envelope. ## Lifecycle and compliance The ±20 V maximum gate-source voltage gives margin for 12 V and 15 V gate-drive rails.","metaTitle":"IRFZ48RSPBF N-Channel MOSFET, 60V 50A TO-263, 18mOhm","metaDescription":"IRFZ48RSPBF N-Channel MOSFET, 60V drain-source, 50A continuous drain, 18mOhm Rds(on) at 10V.

The original IRFZ48 was a through-hole TO-220AB part; the RSPBF suffix indicates the D²Pak package and lead-free plating. Electrically the ratings are similar, but the package footprint is different — the TO-263 requires a surface-mount land pattern, not through-hole holes. A direct board-level replacement is not possible without a PCB layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/IRFZ48RSPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/IRFZ48RSPBF when reusing this data.
