Supply is limited to existing distributor inventory and the independent surplus channel. For a BOM line that still specifies this exact order code, procurement now depends on broker-sourced inventory. At 12 A, expect roughly 4 W dissipation in the channel alone — well within the 70 W package limit at case temperature Tc, but the junction-to-case thermal path needs a good copper spread on the DPAK tab to keep junction temperature under 175°C. At 5 V gate drive the on-resistance will be higher than the 28 mOhm figure — check the typical output characteristic curve in the datasheet if your gate driver rail is 5 V. ## P-channel in DPAK — thermal and layout notes The 175°C junction temperature rating gives headroom for high ambient environments like automotive under-hood or industrial enclosures. ## Gate charge and switching considerations","metaTitle":"STD30PF03LT4 P-Channel MOSFET, 30V, 24A, DPAK, Obsolete","metaDescription":"STMicroelectronics STD30PF03LT4 P-Channel MOSFET, 30V Vdss, 24A Id, 28mOhm Rds(on) at 12A, DPAK package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"STripFET™ II","Package":"Tape & Reel (TR)","FET Type":"P-Channel","Vgs (Max)":"±16V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPAK (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1V @ 250µA","Base Product Number":"STD30","Operating Temperature":"175°C (TJ)","Rds On (Max) @ Id, Vgs":"28mOhm @ 12A, 10V","Power Dissipation (Max)":"70W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"28 nC @ 5 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"1670 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"5V, 10V","Current - Continuous Drain (Id) @ 25°C":"24A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD30PF03LT4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STD30PF03LT4?","answer":"For a pin-compatible P-channel MOSFET in DPAK with similar voltage and current ratings, a cross-reference search against parts like the STD30PF03L or newer STripFET F7 series equivalents is the practical path.
