LM4041C12IDCKR

Texas Instruments · Voltage Reference · SC-70-5

LM4041C12IDCKR from Texas Instruments, in a SC-70-5. 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 Anode power_in Anode pin, normally grounded; the datasheet lists its type as output (O) but it functions as the reference ground-side connection.
2 NC* unconnected Must float or connect to anode (pin 1), per the datasheet; TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise environments.
3 Cathode bidirectional Shunt current and output voltage pin; continuous cathode voltage is 15 V max and continuous cathode current is -10 mA to 25 mA (absolute maximum), with a 12 mA maximum recommended operating current.
4 NC unconnected No-connect pin, listed as NC in the SC70 pin table.
5 NC unconnected No-connect pin, listed as NC in the SC70 pin table.
