AZ431LANTR-E1

AZ431LANTR-E1 is a Diodes Incorporated adjustable shunt voltage reference in a SOT-23 package, built around a 1.24 V internal reference with A-grade ±0.5% initial accuracy, an output adjustable from 1.24 V to 18 V, cathode current from 0.1 mA to 100 mA and a typical temperature coefficient of 20 ppm/°C — the low-cost regulation and feedback element for isolated power supplies, battery chargers and voltage monitors. Lifecycle note: Diodes marks this exact code NRND (not recommended for new designs) in the ordering table of its datasheet DS36801 Rev. 5; for new designs use the AZ431LANTR-G1, which Diodes lists as In Production, while the -E1 remains the correct code for sustaining builds already qualified on it. Selection advice: shunt references are specified by accuracy grade and tempco, not by the base AZ431L name — confirm the A grade in the code, and size the cathode bias network so current stays inside the 0.1 mA to 100 mA window across line and load. Parameters verified against Diodes Incorporated documentation.
