# MBRF2045CTD

**DIYI Elec Tech** · Schottky Barrier Diodes (SBD) · ITO-220AB

MBRF2045CTD from DIYI Elec Tech, in a ITO-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, with the cathode at pin 2; MBRF2045CTD is rated 45 V VRRM and 20 A average forward current, with VF of 0.65 V at 10 A per leg. |
| 2 | K | passive | Common cathode of both Schottky diodes (center pin), rated for 45 V maximum DC blocking voltage and 150 A peak surge current (8.3 ms half sine-wave). |
| 3 | A2 | passive | Anode of the second Schottky diode, with the cathode at pin 2; MBRF2045CTD is rated 45 V VRRM and 20 A average forward current, with VF of 0.65 V at 10 A per leg. |
