# SK32B-LTP

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

SK32B-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 (marked end of the SMB body); SK32B-L blocks 20V maximum DC reverse voltage (28V... see review) with IR of 0.1mA at TJ=25°C and 10mA at TJ=100°C at rated DC blocking voltage. |
| 2 | A | passive | Anode; SK32B-L conducts 3.0A average forward current (TL=105°C) with a maximum instantaneous forward voltage of 0.5V at IFM=3.0A and 100A peak surge (8.3ms half sine). |
