Rated for a load voltage range of 6 V to 52 V, it covers 12 V and 24 V automotive electrical systems with margin, and reaches into 48 V mild-hybrid bus architectures. The single output delivers up to 1.8 A continuous, limited by the package thermal path through the PG-TO252-5 exposed pad. The switch uses a simple On/Off interface with non-inverting input logic — no Vcc supply rail needed, just the load voltage on the drain. At 1.8 A output, the 150 mOhm typical on-resistance produces about 0.5 W conduction loss (I²R). In the PG-TO252-5 package with the exposed tab soldered to a copper plane, that keeps the junction rise within the 150°C ceiling at 85°C ambient. If the load draws closer to the 1.8 A maximum continuously, the PCB copper area under the tab sets the real thermal limit — a 1-inch² pour is the practical minimum for sustained operation. The 6 V to 52 V load voltage range means the same part works across 12 V headlamp relays, 24 V truck solenoids, and 48 V starter-generator pre-charge circuits. The over-voltage clamp protects the load during load-dump transients up to the 52 V maximum. ## Obsolete — sourcing through the independent channel The BTS452TT carries an Obsolete lifecycle status from Infineon. Production has ended; the only supply channel is the independent distribution market — surplus, new-old-stock, and broker inventory. ## Package and footprint — PG-TO252-5 The BTS452TT is supplied in a PG-TO252-5 package (DPak with 4 leads plus tab, also known as TO-252AD). The tab is the drain terminal. Store the reels in a dry environment — the package is moisture-sensitive, and the reel seal should remain intact until the board assembly reflow step.","metaTitle":"BTS452TT miniPROFET High-Side Switch, 150 mOhm, Obsolete","metaDescription":"Infineon BTS452TT automotive AEC-Q100 high-side power switch, 1.8A output, 150 mOhm Rds(on), 6V-52V load range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, miniPROFET®","Package":"Tape & Reel (TR)","Features":"Auto Restart","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":"Obsolete","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","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.5700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1698bdc322dd0aeb368056e69cab838d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BTS452TT?","answer":"No official replacement or successor part number is recorded for the BTS452TT.
