For a 5 V rail set with a 2.495V reference and a 1:1 divider, the output stays within 50 mV of target at 25°C before temperature drift. The 100 mA cathode current capability drives the optocoupler LED in an isolated flyback supply or sinks the feedback node of a linear regulator. The 700 µA minimum cathode current ensures the reference stays in regulation at light load. It does not carry an automotive-grade rating, so it is not specified for under-hood or chassis-mounted applications where AEC-Q100 qualification is required. The SOT-89-3 package (TO-243AA) has a large collector tab on the cathode pin that doubles as a thermal path. In a typical feedback application dissipating under 50 mW, the junction temperature stays well within the operating range with standard FR-4 copper area. The base product number TL432 spans multiple tolerance and package variants, so the BOM should specify the full TL432AIPK to lock in the ±1% grade and SOT-89-3 footprint.","metaTitle":"TL432AIPK Shunt Voltage Reference, ±1% Tolerance, SOT-89-3","metaDescription":"Texas Instruments TL432AIPK adjustable shunt voltage reference, 2.495V min output, ±1% tolerance, 100 mA output, -40°C to 85°C, SOT-89-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-243AA","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-89-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432AIPK/alternatives.json"},"ai":{"faq":[{"question":"Is TL432AIPK a direct replacement for TL431?","answer":"The TL432 is functionally identical to the TL431 — same 2.495V reference, same adjustable output to 36 V, same 100 mA cathode current.
