This part is obsolete, so if you're staring at a scorch mark on a board with one of these, the repair path is a pin-compatible replacement or a board rework to accept the more common TL431 pinout. ## 100 mA cathode current — load-driving reality Rated for 100 mA continuous output current with a minimum cathode current of 1 mA to maintain regulation. The ±2.2% tolerance on the reference voltage is tighter than the standard ±2.5% grade, which matters for precision supply rails or comparator thresholds where the setpoint needs to stay within a few millivolts. ## Obsolete — sourcing the replacement The closest functional equivalent is the TL431 family, but the pinout difference (cathode and reference swapped) means a direct drop-in replacement requires the TL432 variant — check the suffix for the SOT-23-5 package.","metaTitle":"TL432CDBVRE4 Shunt Voltage Reference, SOT-23-5, Obsolete","metaDescription":"TL432CDBVRE4 adjustable shunt voltage reference, 2.495V ref, 100 mA output, ±2.2% tolerance, SOT-23-5 package, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","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-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432CDBVRE4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TL432CDBVRE4?","answer":"The TL432 family (same pinout, same function) in a SOT-23-5 package is the closest drop-in replacement.
