It delivers a single output with a typical Rds(on) of 4.4 mOhm and a maximum current capability of 70 A, making it suited for high-current automotive and industrial loads such as motors, solenoids, and resistive heaters. ## Fault protection and thermal range Built-in fault protection covers current limiting (fixed), open load detection, over-temperature, and over-voltage events — the switch auto-restarts after a fault clears. Housed in a TO-263-8 D²Pak (7 leads plus tab) with a surface-mount footprint. The PG-TO220-7-4 supplier device package is a through-hole alternative variant — confirm the exact package code on your BOM line before ordering. ## Last Buy — final procurement window This means Infineon has announced end-of-life for this order code and the final purchase window is open. No official successor is listed on the record.","metaTitle":"BTS500551TMAATMA1 PROFET high-side switch, 4.4 mOhm","metaDescription":"Infineon BTS500551TMAATMA1 PROFET high-side switch, 4.4 mOhm Rds(on), 70 A max, TO-263-8.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tape & Reel (TR) Cut Tape (CT)","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":"Surface Mount","Package / Case":"TO-263-8, D²Pak (7 Leads + Tab), TO-263CA","Product Status":"Last Time Buy","Voltage - Load":"5V ~ 34V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS50055","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"70A","Supplier Device Package":"PG-TO220-7-4","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4509","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87ec1472c69b349af628b4e00c1491d1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BTS500551TMAATMA1/alternatives.json"},"ai":{"faq":[{"question":"Can BTS500551TMAATMA1 handle inductive loads?","answer":"Yes — the PROFET family is designed for driving inductive loads such as relays, solenoids, and DC motors.
