The SOT-23-3 package suits compact PCB layouts in engine control units, body controllers, and sensor interface modules where a stable bias rail is needed. ## Temperature range and output drive The shunt can sink up to 15 mA continuous output current, with a cathode current floor of 600 µA — enough to bias an optocoupler LED or drive a small load in a feedback loop. For dual-sourcing, the TL432 family shares pin-compatibility across its standard and automotive grades, but no official cross-reference is listed for this exact code.","metaTitle":"TL432LIAQDBZRQ1 Automotive Shunt Regulator, AEC-Q100","metaDescription":"TL432LIAQDBZRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±1% tolerance, SOT-23-3 package, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/960725404a96d9b0e89f219adcdedfe0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432LIAQDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"How does TL432LIAQDBZRQ1 compare to the standard TL431?","answer":"The TL432LIAQDBZRQ1 is the automotive-grade (AEC-Q100) variant of the TL432 family, which itself is a lower-voltage version of the TL431.
