LM4040D41IDBZR

Texas Instruments · Voltage Reference · SOT-23

LM4040D41IDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE passive Parallel current/voltage input; the cathode current IZ must stay within the recommended 15 mA maximum (absolute maximum continuous cathode current is 25 mA, minimum −10 mA).
2 ANODE passive General-purpose pin, normally connected to ground; a parasitic Schottky diode exists between pins 2 and 3 in the SOT-23 package.
3 * passive Must be left floating or connected to the anode (pin 2); TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise.
