Product details

Cathode current and shunt biasing

Minimum cathode current is 65 µA; maximum output current is 15 mA.

Package and mounting

Housed in a SOT-23-3 package (also known as TO-236-3 or SC-59), this is a three-terminal device: cathode, anode, and no-connect. The SOT-23 footprint is standard for small-signal transistors and references, so board layout is straightforward. The part is surface-mount only; no through-hole variant exists in this series.

Lifecycle and sourcing

The LM4050AEM3-2.5/NOPB is an active product with no end-of-life notice. It is ROHS3 compliant. No LTB risk for new designs.

Frequently asked questions

What is the accuracy of LM4050AEM3-2.5/NOPB?

The initial tolerance is ±0.1%. Temperature drift is 50ppm/°C.

Does LM4050AEM3-2.5/NOPB come in tape and reel?

Yes, it is available in Tape & Reel (TR) and Cut Tape (CT) options.

What are the alternatives to LM4050AEM3-2.5/NOPB?

The LM4132AMF-4.1/NOPB is a series reference with tighter tolerance (±0.05%) and lower drift (20ppm/°C), but it has a 4.096V output and requires a supply voltage — it is not a pin-compatible shunt replacement. For a shunt reference with the same footprint, consider the LM4050 family in other voltage options.

Is LM4050AEM3-2.5/NOPB RoHS compliant?

Yes, it is ROHS3 compliant.
