# MBR40150PT-B

**YFW** · Schottky Barrier Diodes (SBD) · TO-247

MBR40150PT-B from YFW, in a TO-247. 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 | A1 | passive | Anode of the first Schottky diode leg (PIN 1 in the schematic symbol), rated 20 A average forward current per leg and 150 V reverse voltage. |
| 2 | K | passive | Common cathode of both Schottky diode legs (PIN 2 in the schematic symbol), with 40 A total average forward current and 150 V maximum reverse voltage. |
| 3 | A2 | passive | Anode of the second Schottky diode leg (PIN 3 in the schematic symbol), rated 20 A average forward current per leg and 150 V reverse voltage. |
