# MBR20100LCT

**Chongqing Pingwei Tech** · Schottky Diodes · TO-220AB

MBR20100LCT from Chongqing Pingwei Tech, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of diode 1. Forward-biased through the internal Schottky junction to the common cathode (pin 2). Rated 10A average forward current per leg, VF typ. 0.71V @ IF=10A. |
| 2 | K | passive | Common cathode for both internal Schottky diodes; electrically connected to the metal mounting tab/case. Handles the summed 20A total device forward current and is typically bonded to the DC output rail and heatsink. |
| 3 | A2 | passive | Anode of diode 2. Forward-biased through the internal Schottky junction to the common cathode (pin 2). Rated 10A average forward current per leg, VF typ. 0.71V @ IF=10A. |
