No external Vcc supply is needed — the switch is self-powered from the load rail. ## Built-in fault protection eliminates external clamp and sense circuits The BTS452RAKSA1 integrates current limiting (fixed threshold), over-temperature shutdown, and over-voltage protection. These features protect the switch and the load during short circuits, overloads, and load-dump transients without requiring external TVS diodes or current-sense resistors. A status flag output and auto-restart behaviour simplify fault recovery in the ECU firmware — the switch attempts to re-close after a thermal shutdown once the junction cools, reducing software overhead for lamp or solenoid loads. ## PG-TO252-5 package with exposed tab for thermal management The device is supplied in a PG-TO252-5-11 package (DPak with 4 leads plus tab), a surface-mount power package. This makes it suitable for both new production builds and ongoing aftermarket support without requalification risk.","metaTitle":"BTS452RAKSA1 Infineon miniPROFET High-Side Switch, 1.8A","metaDescription":"Infineon BTS452RAKSA1 Automotive AEC-Q100 miniPROFET high-side power switch. 1.8A output, 150mOhm Rds(on), 6V-52V load range, -40 to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, miniPROFET®","Package":"Tube","Features":"Auto Restart, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"150mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","Product Status":"Active","Voltage - Load":"6V ~ 52V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS452","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"1.8A","Supplier Device Package":"PG-TO252-5-11","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1e614759e7cc445fedfbd174b5a7487.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the BTS452RAKSA1 and get a price quote?","answer":"Submit a request with your target quantity and we will confirm current availability and pricing at quote time."},{"question":"Is BTS452RAKSA1 a replacement for BTS452R?","answer":"The evidence does not list an official cross-reference or successor relationship between BTS452RAKSA1 and BTS452R.
