# MBR20150DCT

**NH** · Schottky Diodes · TO-220AB

MBR20150DCT from NH, in a TO-220AB. 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 (Pin1), whose cathode is the common Pin2/case; rated 150 V VRRM and 20 A total average forward current for the device. |
| 2 | K/CASE | passive | Common cathode of both Schottky diodes, which the datasheet's polarity diagram also shows connected to the CASE (mounting tab). |
| 3 | A2 | passive | Anode of the second Schottky diode (Pin3), whose cathode is the common Pin2/case; rated 150 V VRRM and 20 A total average forward current for the device. |

## CAD (KiCad official)

- Symbol: `MBR20150DCT`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220AB (KiCad packages3D, STEP)
- 3D model files: `mbr20150dct-etched.step` / `mbr20150dct-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mbr20150dct.step` / `mbr20150dct.glb` are the bare package body.
