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. ## Package and footprint Housed in a TO-263-8 D²Pak (7 leads plus tab) with a surface-mount footprint. The large exposed tab carries the drain current and must be soldered to a sufficient copper area on the PCB to keep the junction temperature within limits under sustained 70 A pulses. 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 The BTS500551TMAATMA1 carries a Last Buy lifecycle status. 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. If you have an active BOM position, secure your lifetime buy quantity now; after the Last Buy date passes, supply will shift to the surplus and broker channel.","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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87ec1472c69b349af628b4e00c1491d1.pdf","sourceUrl":null},"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.
