# 1SMA5928A

**hongjiacheng** · Zener Diodes · DO-214AC(SMA)

1SMA5928A from hongjiacheng, in a DO-214AC(SMA). 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 | Two-terminal Zener cathode, identified by the cathode line on the package body; the 1SMA5928A nominal Zener voltage is 13 V (min 12.35 V, max 13.65 V) at IZT = 28.8 mA. |
| 2 | A | passive | Two-terminal Zener anode, the terminal opposite the cathode line; forward voltage is 1.5 V max at IF = 200 mA per the family rating table. |
