# 1SMA4754_R1_00001

**PANJIT International** · Zener Diodes · SMA(DO-214AC)

1SMA4754_R1_00001 from PANJIT International, in a SMA(DO-214AC). 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 of the zener diode, marked by the color band at the cathode end of the SMA (DO-214AC) body; the datasheet gives no separate electrical limit for this pin beyond the 1 W power and zener ratings. |
| 2 | Anode | passive | Anode of the zener diode, at the end opposite the color band; the datasheet gives no separate electrical limit for this pin beyond the 1 W power and zener ratings. |
