TL4050B25IDCKR 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 (low-side return); connect to GND rail; in high-EMI applications TI recommends connecting the NC pin to this pin. |
| 2 | NC | unconnected | No internal connection; middle pin on left side of SC-70-5 body; leave unconnected or connect to Anode per high-EMI guidance. |
| 3 | CATHODE | power_out | Cathode; regulated 2.5 V shunt reference output; operating cathode current IZ = 60 μA (typ) to 15 mA (max); dynamic impedance ZZ = 0.3 Ω typ at IZ = 1 mA, 120 Hz. |
| 4 | NC | unconnected | No internal connection; bottom pin on right side of SC-70-5 body. |
| 5 | NC | unconnected | No internal connection; top pin on right side of SC-70-5 body; TI recommends connecting to Anode in high-EMI applications. |
