Product details

Adjustable shunt reference, ±0.5% tolerance

It delivers a 2.495 V minimum output, adjustable up to 36 V, with a ±0.5% tolerance that makes it a solid choice for precision feedback loops in offline power supplies and isolated DC-DC converters.

100 mA output, 600 µA cathode current

Rated for 100 mA continuous output current, this shunt reference can drive an optocoupler LED directly in a secondary-side feedback circuit. The 600 µA minimum cathode current keeps the device biased properly even at light load, which matters when you are sizing the bias resistor for the full load range.

Frequently asked questions

What is the tolerance of TL432BCDBZTG4?

The TL432BCDBZTG4 has a ±0.5% tolerance on the reference voltage, which is the tightest common grade in the TL432 family and suits precision regulation applications.

Is TL432BCDBZTG4 equivalent to TL431?

The TL432 is functionally equivalent to the TL431 in a smaller SOT-23-3 package. Both are adjustable shunt references with the same 2.495 V internal reference and 36 V maximum output. The TL432 uses a different pinout (anode, cathode, reference) — confirm the PCB footprint before substitution.
