It drives resistive, inductive, or lamp loads up to 640 mA continuous on a 42 V max supply rail, with the load connected between the drain and the positive supply — the switch sinks current to ground when the non-inverting input is driven high. The on-resistance is 500 mOhm max at 640 mA. The PG-SOT223-4 package dissipates the resulting conduction loss. ## Fault protection that keeps the load alive Three built-in protection circuits make this a self-protecting switch: fixed current limiting prevents the output from exceeding its safe area, over-temperature shutdown protects the die if the junction hits the limit, and over-voltage clamping absorbs load-dump transients on the battery line. The auto-restart feature means the switch re-tries after a fault clears — useful for driving bulbs or motors where a temporary overload is expected. The 150°C TJ ceiling gives headroom for self-heating in a sealed enclosure. ## Obsolete — what that means for procurement The BTS3207NNT carries an Obsolete lifecycle status from Infineon.","metaTitle":"Infineon BTS3207NNT HITFET Low-Side Switch, 42V 640mA","metaDescription":"Infineon BTS3207NNT HITFET protected low-side switch: 42V max load, 640mA output, auto-restart, fault protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"HITFET®","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)":"500mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","Product Status":"Obsolete","Voltage - Load":"42V (Max)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS3207","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"640mA","Supplier Device Package":"PG-SOT223-4","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f6b8484bcd7947f715c369526ba7e423.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BTS3207NNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BTS3207NNT when reusing this data.
