For a load-switch or low-frequency PWM application below 20 kHz, the gate charge is essentially irrelevant; the static Rds(on) and the thermal impedance of the D2PAK pad to the PCB copper are the design parameters that matter. ## Active production, sourced to order For volume BOM commitments, the part is specified into the bill of materials and sourced on a per-order basis.","metaTitle":"IRLZ44ZSPBF HEXFET N-Channel MOSFET, 55 V, 13.5 mOhm","metaDescription":"IRLZ44ZSPBF HEXFET N-channel MOSFET, 55 Vdss, 13.5 mOhm Rds(on) at 10 V, 51 A continuous drain, logic-level gate drive, D2PAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"HEXFET®","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±16V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"3V @ 250µA","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"13.5mOhm @ 31A, 10V","Power Dissipation (Max)":"80W (Tc)","Supplier Device Package":"D2PAK","Gate Charge (Qg) (Max) @ Vgs":"36 nC @ 5 V","Drain to Source Voltage (Vdss)":"55 V","Input Capacitance (Ciss) (Max) @ Vds":"1620 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"51A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b115a363070061375a79c3374690212.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IRLZ44ZSPBF/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRLZ44ZSPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRLZ44ZSPBF when reusing this data.
