Its typical on-resistance of 4.4 mOhm sets the conduction loss floor. The 55 A maximum output current rating covers heavy loads like motors, solenoids, and pre-charge circuits. The load voltage range spans 5 V to 34 V. The switch does not require a Vcc supply — it self-powers from the load pin, simplifying the BOM by eliminating a separate bias rail. Fault protection includes fixed current limiting, open load detection, over-temperature shutdown, over-voltage clamp, short-circuit protection, and under-voltage lockout. ## Package and mounting — TO-220-7 formed leads The BTS500551TMB comes in a TO-220-7 package with formed leads (P-TO220-7-11), a through-hole footprint that suits power-dissipation designs requiring a heatsink. The 7-lead layout is specific to this PROFET family — verify the hole pattern against the board layout before committing. ## Lifecycle and sourcing posture Sourced through independent distribution, it is quoted to order against the BOM quantity. No official successor or pin-compatible alternate is listed in the cross-reference; for dual-sourcing options, contact the sourcing desk with the target quantity and application voltage.","metaTitle":"Infineon BTS500551TMB High-Side Power Switch, 4.4 mOhm, 55A","metaDescription":"Infineon BTS500551TMB high-side power switch: 4.4 mOhm typical Rds(on), 55A max output, 5V-34V load range, TO-220-7.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Bulk","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"4.4mOhm","Mounting Type":"Through Hole","Package / Case":"TO-220-7 Formed Leads","Product Status":"Active","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Load, Over Temperature, Over Voltage, Short Circuit, UVLO","Number of Outputs":"1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"55A","Supplier Device Package":"P-TO220-7-11","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.3400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eb7b7abb044e986a73d4444818d0e8da.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of BTS500551TMB?","answer":"The typical on-resistance is 4.4 mOhm.
