Infineon BSC027N OptiMOS MOSFETs
Infineon BSC027N OptiMOS N-channel MOSFETs in TDSON-8 — 40V and 60V suffixes, not one interchangeable die.
BSC027N OptiMOS family — 40V vs 60V TDSON-8
Compare BSC027N04LSG and BSC027N06LS5 before you lock a 40V or 60V MOSFET on the BOM.
BSC027N is an Infineon OptiMOS N-channel prefix in SuperSO8 / TDSON-8, not a single orderable MPN. The three lines on this page share the same package family but split on voltage class: BSC027N04LSG and BSC027N04LSGATMA1 are 40V devices (24A / 100A class in the listing), while BSC027N06LS5ATMA1 is a 60V, 100A part. A 40V suffix will not survive a 60V rail.
04LSG versus 04LSGATMA1 is typically the same electrical device with a different order / tape-and-reel code (ATMA1). Still copy the full MPN onto the PO — Infineon packaging, reel quantity, and PCN tracking sit on the suffix. Decode LSG versus LS5 on the datasheet; do not assume they are the same generation or RDS(on) bin.
Use the variant table to pick the exact code, then open the product page for stock and RFQ. If you only have a marking that starts with BSC027N, send a photo of the reel or board so we can tell 40V from 60V before quoting.
Key Features
- 40V and 60V voltage classes04 suffixes are 40V; 06LS5 is 60V. Do not mix them on the same rail.
- TDSON-8 / SuperSO8 footprintAll three listed parts use an 8-pin TDSON EP outline — still verify the land pattern drawing.
- OptiMOS N-channel, logic-level familyLSG / LS5 tokens mark generation and RDS(on) bin. Confirm VGS and RDS(on) on the PDF.
- ATMA1 is an order code, not a new dieBSC027N04LSG and BSC027N04LSGATMA1 are the same 40V device with different packaging codes.
Target Applications
- Synchronous buck and point-of-load converters
- 24V / 48V industrial switching stages (use the 60V suffix where needed)
- OR-ing, hot-swap, and high-current load switches
- Second-source or last-time-buy of an existing BSC027N marking

Ordering Code Differences
How suffixes on BSC027N map to package, grade, and reel options.
BSC027N + voltage + technology + packaging. Two 40V lines can share silicon; a 60V line does not.
04LSG / 04LSGATMA1 — 40V N-channel, TDSON-8. ATMA1 is Infineon’s tape-and-reel / order identifier. Match the full code on the PO.
06LS5ATMA1 — 60V N-channel, TDSON-8. Recalculate SOA and avalanche if you came from a 40V BSC027N04 design.
Copy the reel label. Reel size, MSL, and quantity per reel sit on the suffix and will not appear on the schematic.
How to Choose the Right BSC027N MOSFETs
Pick voltage class first
BSC027N04 is 40V; BSC027N06LS5 is 60V. A lower VDS suffix is not a second source for a higher-voltage design.
Then confirm RDS(on) and current
Listings show 24A / 100A class. Use the datasheet curves at your VGS and case temperature, not the prefix alone.
Treat ATMA1 as packaging
BSC027N04LSG vs BSC027N04LSGATMA1 is usually reel / order-code, not a different MOSFET. Still quote the exact MPN.
Keep the full suffix on the BOM
Do not enter only BSC027N. RFQ with quantity, date code, and whether you need the 40V or 60V line.
