Product details

Precision 5V shunt reference in a small SOT-23-3

Typical applications include precision data converters, battery-powered instrumentation, and portable test equipment where a stable, low-noise reference voltage is needed. As a shunt reference, it behaves like a Zener diode — it requires an external series resistor to bias the cathode current, which is set at 80 µA typical. The output current capability is 15 mA, sufficient to drive the reference input of most ADCs and DACs without additional buffering.

The SOT-23-3 package is widely second-sourced, so supply continuity is good.

Frequently asked questions

Is TL4050A50IDBZT a direct replacement for TL4050A50IDBZ?

The suffix T indicates Tape & Reel packaging (TR) and Cut Tape (CT). The TL4050A50IDBZ (without T) is the same device in bulk or tube packaging. Electrically and mechanically they are identical — the T variant is the reeled version for automated assembly.

Is TL4050A50IDBZT RoHS compliant?

Yes, it is ROHS3 Compliant.
