Maximum Rds(on) is 192 mOhm at 8 A, 10 V gate drive. The 110 W Tc-rated dissipation can handle conduction loss with a heatsink. ## Capacitance and switching loss — the 1260 pF Ciss at 100 V Input capacitance is 1260 pF at 100 V drain-source — a moderate figure that keeps the Miller plateau short and the turn-on/turn-off delay within a few tens of nanoseconds with a standard 10-ohm gate resistor. ## Package and mounting — TO-220-3 for heatsink attachment The ±25 V maximum gate-source rating gives margin for gate-drive ringing in a hard-switched topology. ## Lifecycle and procurement reality The device is RoHS3 compliant.","metaTitle":"STP18N55M5 MOSFET N-CH 550V 16A TO-220-3 MDmesh V","metaDescription":"STMicroelectronics STP18N55M5 N-channel MOSFET, 550V Vdss, 16A Id, 192mOhm Rds(on), TO-220-3.","metaKeywords":null},"attributes":{"series":"MDmesh™ V","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ V","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±25V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STP18","Operating Temperature":"150°C (TJ)","Rds On (Max) @ Id, Vgs":"192mOhm @ 8A, 10V","Power Dissipation (Max)":"110W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"31 nC @ 10 V","Drain to Source Voltage (Vdss)":"550 V","Input Capacitance (Ciss) (Max) @ Vds":"1260 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"16A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1000","priceTiers":[{"qty":1,"price":"$3.10000","currency":"USD"},{"qty":10,"price":"$2.60100","currency":"USD"},{"qty":100,"price":"$2.10430","currency":"USD"},{"qty":500,"price":"$1.87052","currency":"USD"},{"qty":1000,"price":"$1.60163","currency":"USD"},{"qty":2000,"price":"$1.50811","currency":"USD"},{"qty":5000,"price":"$1.44688","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/236ee7ebd2a721ef65c08596a5f4f84a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP18N55M5/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP18N55M5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP18N55M5 when reusing this data.
