Its 8 mOhm typical on-resistance keeps the voltage drop and self-heating low at full current — at 9A the conduction loss is about 0.65 W, which the TO-220-7 package can sink to a heatsink or PCB copper. The 5.5V to 38V load supply range covers 12V and 24V automotive and industrial rails. ## Comprehensive fault protection — fewer external clamp circuits The BTS50090-1TMB integrates current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping. That means a single device handles the protection functions that would otherwise require a current-sense resistor, comparator, and TVS diode. The On/Off interface with a non-inverting input simplifies the drive from a 3.3V or 5V logic pin. This part carries an Obsolete lifecycle status. No official replacement is listed on the Infineon cross-reference; any substitution requires a pin-compatible PROFET with similar Rds(on) and current rating, verified against the board layout. ## TO-220-7 — through-hole for hand-solderable repairs The PG-TO-220-7-12 package is a 7-lead through-hole TO-220 variant. The exposed metal tab provides a low thermal resistance path to the heatsink. For a rework or repair scenario, this package is hand-solderable with a standard iron — no hot-air reflow needed. The 0.50 mm pitch between leads is wide enough for manual soldering without bridging.","metaTitle":"Infineon BTS50090-1TMB PROFET High-Side Switch, 8 mOhm, 9A","metaDescription":"Infineon BTS50090-1TMB PROFET high-side power switch, 8 mOhm typical Rds(on), 9A max output, TO-220-7.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"PROFET®","Package":"Tube","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"8mOhm","Mounting Type":"Through Hole","Package / Case":"TO-220-7","Product Status":"Obsolete","Voltage - Load":"5.5V ~ 38V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS50090","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"9A","Supplier Device Package":"PG-TO220-7-12","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2afe55da0b271eac00fdec3d36bd5ebb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for the BTS50090-1TMB?","answer":"No official replacement or successor part is listed on the Infineon cross-reference for this order code.
