The SOT-23-5 package is a common five-pin footprint for this function class. ## 100 mA cathode current — what it buys you The device sinks up to 100 mA continuous cathode current. That is enough to bias an optocoupler LED in a feedback loop or drive a small load directly, but it is not a power regulator — the shunt dissipates (V_KA × I_K) as heat, so the SOT-23-5 junction limits the practical continuous current below 100 mA at elevated ambient. Minimum cathode current is 600 µA, which sets the lower bound on the bias resistor value. Below that the reference may drop out of regulation. The TL432ACDBVRE4 is listed as obsolete. For new designs or replacement, the TL431 (same function, different pinout) is a common cross-shopped alternative — confirm the pin configuration against your layout before substituting.","metaTitle":"TL432ACDBVRE4 Shunt Regulator, 2.495 V ±1%, SOT-23-5","metaDescription":"TL432ACDBVRE4 adjustable shunt voltage reference, 2.495 V output, ±1% tolerance, 100 mA cathode current, SOT-23-5 package.","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":"±1%","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":"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-23-5","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/TL432ACDBVRE4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432ACDBVRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432ACDBVRE4 when reusing this data.
