The part comes in a compact SC-70 / SOT-323 surface-mount package (PG-SOT323), making it suitable for low-power load switching, level shifting, and signal gating on space-constrained boards. Gate threshold voltage is 1.4 V maximum at 26 µA, so a 3.3 V logic signal can turn it on — but the drive voltage table lists 4.5 V and 10 V for the rated on-resistance, meaning a 3.3 V gate drive will not achieve the headline Rds(on) figure. The 500 mW power dissipation (at 25°C ambient) is the package limit — in a 85°C ambient, derate to roughly 300 mW. ## Lifecycle status — obsolete, sourced through independent distribution Infineon lists the BSS138W as Obsolete. No last-time-buy window or successor part number is published in the available records. There is no factory lead time to manage; the supply is what the open market holds.","metaTitle":"Infineon BSS138W E6327 N-Channel MOSFET, 60V 280mA SC-70","metaDescription":"Infineon BSS138W E6327 N-Channel SIPMOS® MOSFET, 60V Vdss, 280mA Id, 3.5Ohm Rds(on), SC-70/SOT-323.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"SIPMOS®","Package":"Tape & Reel (TR)","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1.4V @ 26µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"3.5Ohm @ 220mA, 10V","Power Dissipation (Max)":"500mW (Ta)","Supplier Device Package":"PG-SOT323","Gate Charge (Qg) (Max) @ Vgs":"1.5 nC @ 10 V","Drain to Source Voltage (Vdss)":"60 V","Input Capacitance (Ciss) (Max) @ Vds":"43 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"280mA (Ta)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/59c9be08ef9e8bdd59ebbf15d902e936.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BSS138W%20E6327/alternatives.json"},"ai":{"faq":[{"question":"What replaces Infineon BSS138W E6327?","answer":"A functionally equivalent replacement must match the 60 V Vdss, 280 mA Id, 3.5 Ohm Rds(on), and SC-70/SOT-323 footprint. The closest pin-compatible alternative in the same family is the standard BSS138 in the same package — check its Rds(on) and gate threshold to confirm fit for your load current and drive voltage."},{"question":"What is the difference between BSS138W and BSS138?","answer":"The BSS138W is a variant of the standard BSS138, typically offered in a different package or with a specific tape-and-reel configuration. Both are N-channel small-signal MOSFETs with similar 60 V / 280 mA ratings. The 'W' suffix often denotes a wider-body package or a specific lead finish. For the BSS138W E6327, the package is SC-70/SOT-323 (PG-SOT323). The standard BSS138 is commonly available in SOT-23. The pinout differs between the two packages, so they are not drop-in replacements without a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BSS138W-E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BSS138W-E6327 when reusing this data.
