The official product status is Obsolete. That means Infineon has stopped manufacturing this specific order code; no last-time-buy window remains open through the factory channel. Any stock you find today is either new-old-stock from distributor overstocks or surplus from the independent market. If you are supporting a legacy board that uses this exact part, you will need to source it through brokers or consider a pin-compatible alternative. ## Key ratings for the design decision The 60 V drain-source rating gives plenty of margin for 12 V or 24 V rails — it is not a part you push to the limit in a 48 V system. The 3.5 Ohm maximum on-resistance at 220 mA gate drive of 10 V is typical for a small-signal MOSFET; at 4.5 V drive the Rds(on) will be higher, so check the gate threshold curve if your logic-level driver only swings 3.3 V. The 280 mA continuous drain current is the DC limit at 25°C ambient; derate for elevated temperature. This part comes in the SC-70 / SOT-323 package, a three-lead surface-mount case. The Infineon supplier device package is PG-SOT323.","metaTitle":"Infineon BSS138W L6327 N-Channel MOSFET, 60 V, 280 mA, SC-70","metaDescription":"Infineon BSS138W L6327 N-Channel SIPMOS MOSFET, 60 V drain-source, 280 mA continuous drain, 3.5 Ohm Rds(on) at 220 mA.
