SA90A from Brightking, in a DO-15. 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 | Cathode, marked by the color band at one end of the body (polarity band denotes cathode for unidirectional models such as SA90A); the SA90A has VRWM 90.0 V, VBR 100.00~111.00 V at IT 1 mA, and VC 146 V at IPP 3.5 A. |
| 2 | A | passive | Anode, the non-banded axial lead of the unidirectional SA90A; the datasheet gives no separate limit for this lead, only the device ratings (500 W peak pulse power at 10/1000 µs, operating/storage range -55 to +150 ℃). |
