The 600 µA minimum cathode current keeps the device biased properly even at light load, which matters when you are sizing the bias resistor for the full load range.","metaTitle":"TL432BCDBZTG4 Shunt Voltage Reference, ±0.5% Tolerance","metaDescription":"Texas Instruments TL432BCDBZTG4 adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, SOT-23-3.","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)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°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":"$0.8400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432BCDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TL432BCDBZTG4?","answer":"The TL432BCDBZTG4 has a ±0.5% tolerance on the reference voltage, which is the tightest common grade in the TL432 family and suits precision regulation applications."},{"question":"Is TL432BCDBZTG4 equivalent to TL431?","answer":"The TL432 is functionally equivalent to the TL431 in a smaller SOT-23-3 package.
