It handles load voltages from 5 V to 58 V, covering 12 V, 24 V, and 48 V automotive and industrial supply rails. The N-channel output is driven by a simple On/Off logic input and includes auto-restart after a fault clears. ## 7.2 mOhm Rds(on) — conduction loss and thermal budget At 38 A the 7.2 mOhm typical Rds(on) yields about 10.4 W conduction loss at 25°C junction — the actual loss climbs with temperature per the normalised curve. ## Fault protection set — overcurrent, open-load, overtemperature, overvoltage The BTS500851 integrates current limiting (fixed threshold), open-load detection, overtemperature shutdown, and overvoltage clamping. The auto-restart feature re-enables the output after the fault condition clears, which is useful for transient overloads in lamp or motor loads. The 1:1 input-to-output ratio means the logic input directly gates the power stage — no external level shifting needed. ## Last Buy — secure inventory now The BTS500851TMAATMA1 carries a Last Buy lifecycle status. This means Infineon has announced end-of-life and the final order window is open. Buyers should commit to their lifetime buy quantities now to avoid a forced redesign.","metaTitle":"Infineon BTS500851TMAATMA1 PROFET High-Side Switch, 7.2 mOhm","metaDescription":"Infineon BTS500851TMAATMA1 PROFET high-side switch: 7.2 mOhm Rds(on), 38 A max output, 5V-58V load range, -40°C to 150°C.","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)":"7.2mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-263-8, D²Pak (7 Leads + Tab), TO-263CA","Product Status":"Last Time Buy","Voltage - Load":"5V ~ 58V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS50085","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"38A","Supplier Device Package":"PG-TO220-7-4","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7963","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd2699a4fa951af863dbaf3880db3f9c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BTS500851TMAATMA1 obsolete?","answer":"It is not yet obsolete, but the end-of-life process has begun.
