LDP01-56AY from STMicroelectronics, in a D2PAK. 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 | A | passive | Anode lead, which must be connected together with the other anode lead (stand-off voltage VRM 48 V for the LDP01-56AY, breakdown VBR 53.3 V min to 58.9 V max at 1 mA). |
| 2 | K | passive | Cathode, connected to the D2PAK tab (the middle lead is not present on the footprint), for the LDP01-56AY clamping VCL max 76 V at 48 A (10/1000 µs). |
| 3 | A | passive | Anode lead, which must be connected together with the other anode lead as stated on the cover page ('Both anodes must be connected'). |
