Packaging

Type: SC-70-5 (SOT-353), 5-pin, surface-mount

Supplier device package: SC-70-5

Shipment form: Tape & Reel (TR) for high-volume pick-and-place

Material: Molded epoxy body with tin-plated leads (RoHS3 compliant)

Size: Ultra-small 5-pin SC-70 class footprint (see datasheet for exact mechanical outline and dimensions)

Pin configuration: 5 leads; anode, cathode, and additional pins per device pinout (refer to datasheet for exact pin assignments)

Thermal characteristics: Low thermal mass; thermal resistance depends on PCB layout and airflow (see datasheet for theta values and derating)

Electrical properties (summary): 2.048 V fixed reference, ±1% tolerance, shunt topology, up to 15 mA output current, 150 ppm/°C tempco, noise per provided spec (verify in datasheet)

Lifecycle

Status: Active in the LM4040 family as of the latest available information; not announced as nearing discontinuation. Always confirm the most current status.

Equivalent/alternative models:

- Texas Instruments LM4040 family variants (different accuracy grades and packages; e.g., other LM4040 2.048 V options in SOT-23 or alternate accuracy bins)

- Analog Devices ADR5040 (2.048 V shunt reference, micropower)

- Microchip MCP1520 (2.048 V series reference; use if a series reference fits your design)

- Maxim/ADI/MAX6002 or similar 2.048 V series references (series topology; verify requirements)

- If you need exact pin-for-pin or grade-specific alternatives, contact Y-IC sales via our website for a tailored cross-list.

If a precise equivalent is not confirmed for your constraints (package, tolerance, topology), please reach out to our sales team on the Y-IC website for expert guidance.
