Product details

2.495 V reference, 36 V max — the rail it regulates

Output tolerance is ±2.2%, which is tighter than the standard TL431's ±2.5% grade — useful when the feedback divider needs a known reference window without trimming.

100 mA output — what it can drive

With 100 mA output current capability, this shunt can sink enough current to bias an optocoupler LED in a flyback supply feedback loop, or serve as a precision reference for an ADC's external reference input. The 1 mA minimum cathode current means the part stays in regulation even at light load.

SOT-23-3 — board-fit and temperature grade

Housed in a SOT-23-3 package (also listed as TO-236-3 / SC-59), this is a three-terminal shunt that sits in the same footprint as the TL431 in SOT-23.

Frequently asked questions

Does TL432IDBZR replace TL431?

The TL432IDBZR is a functional equivalent to the TL431 in the same SOT-23-3 footprint, with a tighter ±2.2% tolerance versus the standard TL431's ±2.5%. Pin-compatible for the three-terminal shunt configuration — confirm the reference voltage and output current match your feedback design.
