Output current capability is 100 mA, with a cathode current of 600 µA minimum to maintain regulation. The ±1% tolerance on the reference voltage is adequate for general-purpose power supply feedback and voltage monitoring in commercial-temperature equipment. ## SOT-89-3 package — footprint and thermal considerations The TL432ACPK is supplied in a SOT-89-3 surface-mount package (also designated TO-243AA). This three-lead package has a large collector tab on the back that provides the primary thermal path to the PCB. At 100 mA output, the power dissipation can reach several hundred milliwatts depending on the programmed output voltage. ## Commercial temperature grade limits application scope It is not specified for industrial or automotive temperature ranges.","metaTitle":"TL432ACPK Shunt Voltage Reference, 2.495V, ±1%, SOT-89-3","metaDescription":"TL432ACPK adjustable shunt reference, 2.495V min, 100 mA output, ±1% tolerance.

A functionally similar alternative is the TL431 family, but the pinout differs — the TL432 uses a different pin arrangement (reference on pin 1, cathode on pin 2, anode on pin 3 in SOT-89-3) compared to the TL431. Verify the pinout against your PCB layout before substituting."},{"question":"Can TL432ACPK replace TL431?","answer":"Not directly — the TL432ACPK and TL431 have different pinouts. The TL432 uses a pin configuration specific to the SOT-89-3 package (reference, cathode, anode), while the TL431 typically uses a different ordering. A PCB layout change or a pin-compatible variant would be required."},{"question":"Where can I buy TL432ACPK?","answer":"Submit an RFQ for current availability and pricing — confirmation is provided at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432ACPK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432ACPK when reusing this data.
