SMBJ7.5CA from Shandong Jingdao Microelectronics, in a SMB. 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 | Cathode | passive | Pin 1 is the cathode terminal in the datasheet PINNING table, which is the unipolar pin assignment; the datasheet gives no electrical limits for this pin alone, and the 600 W peak pulse power and -65 to +150 °C storage/junction range apply to the device. |
| 2 | Anode | passive | Pin 2 is the anode terminal in the datasheet PINNING table, which is the unipolar pin assignment; the datasheet gives no electrical limits for this pin alone, and the 600 W peak pulse power and -65 to +150 °C storage/junction range apply to the device. |
