Packaged in a PG-TISON-8, it targets space-constrained power stages where two FETs share a common drain pad and the load currents are unequal — typical in synchronous buck converters, motor driver half-bridges, and battery management switching paths. ## Asymmetric channels — why the different current ratings One channel is rated for 19A continuous, the other for 41A. This asymmetry matches a half-bridge where the low-side FET carries the inductor current for a larger portion of the switching period (synchronous buck) or where the high-side sees pulsed current while the low-side handles the DC freewheel current. The 2.5W package power limit means the total dissipation across both channels combined is the real constraint in a real board — the 41A figure assumes ideal heatsinking on the larger channel. No end-of-life notice on record, so this part is safe to specify into new designs without an LTB risk.","metaTitle":"Infineon BSG0811NDATMA1 OptiMOS Dual N-Ch MOSFET","metaDescription":"Infineon BSG0811NDATMA1 OptiMOS dual N-channel MOSFET, 25V Vdss, 3mOhm Rds(on), 19A/41A continuous drain current.

The dual asymmetrical N-channel configuration with one channel rated for 19A and the other for 41A at 25V Vdss is suited for a motor driver half-bridge. The logic-level gate drive allows direct connection to a 3.3V or 5V MCU PWM output. The 3mOhm Rds(on) keeps conduction losses low, but the 2.5W package power limit means the total dissipation across both channels must be managed with adequate PCB heatsinking."},{"question":"What is the closest pin-compatible alternative to BSG0811NDATMA1 in this component family?","answer":"The BSG0810ND is a known sibling in the same OptiMOS family and same PG-TISON-8 package. Verify the pinout and electrical ratings against your design before substituting — the BSG0811NDATMA1 has asymmetric 19A/41A channels, while the BSG0810ND may carry different current ratings or Rds(on) values."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BSG0811NDATMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BSG0811NDATMA1 when reusing this data.
