SMB5362A
XCH(旭昌辉) · IC · SMB
SMB5362A from XCH(旭昌辉), 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 | K | passive | Cathode, marked by the color band on the package; for SMB5362A the nominal zener voltage is 28 V (26.60 V min to 29.40 V max) and the DC power dissipation is 5.0 W at TL = 75 °C. |
| 2 | A | passive | Anode, the end without the color band; maximum forward voltage is 1.2 V at 200 mA and junction/storage temperature is -55 to +150 °C. |
