# SK3150B-LTP

**MCC Micro Commercial Components** · Schottky Diodes · DO-214AA(SMB)

SK3150B-LTP from MCC Micro Commercial Components, in a DO-214AA(SMB). 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 | K | passive | Cathode, the terminal on the end with the cathode mark band; the device blocks 150V DC (VRRM 150V) and carries 3.0A average forward current at TL=120°C. |
| 2 | A | passive | Anode, the terminal opposite the cathode mark; forward voltage is 0.86V max at IFM=3.0A, TJ=25°C. |
