At a 10 A continuous load, conduction loss is I²R = 10² × 0.13 = 13 W. With a maximum junction temperature of 150 °C and a power dissipation rating of 125 W (case temperature referenced), the part can handle 13 W with a properly sized heatsink — the TO-263 tab is the primary thermal path, and a copper-plane area on the PCB or an external heatsink is required to keep the junction below 150 °C at a 10 A steady-state load.","metaTitle":"BUZ30A H3045A SIPMOS N-Channel MOSFET, 200V 21A TO-263","metaDescription":"Infineon SIPMOS N-channel power MOSFET, 200V Vdss, 21A continuous drain, 130mOhm Rds(on).

At 10 A continuous drain current, conduction loss is about 13 W (I² × 130 mOhm). The maximum power dissipation is 125 W at the case, but without a heatsink the junction temperature will exceed the 150 °C maximum."},{"question":"Can the BUZ30A H3045A be used in a 48 V switching supply?","answer":"Yes. The 200 V drain-source rating provides more than 3× margin above a 48 V nominal rail, even accounting for switching overshoot. The 1900 pF input capacitance at 25 V drain-source is moderate — the gate driver must supply the charge for the target switching frequency, but the 10 V drive voltage is standard for this class of MOSFET."},{"question":"Is the BUZ30A H3045A RoHS compliant and lead-free?","answer":"The evidence does not list a RoHS compliance status or lead-free finish explicitly. For a definitive answer, verify the date-code-specific RoHS certificate from the manufacturer or request it with your RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BUZ30A-H3045A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BUZ30A-H3045A when reusing this data.
