AnBon · ESD And Surge Protection (TVS/ESD) · SOD-123
SMF54A from AnBon, in a SOD-123. 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 of the unidirectional TVS, marked by the cathode band; SMF54A has 54 V reverse standoff voltage, 60.0 V to 66.3 V breakdown at 1.0 mA, and 87.1 V max clamping at 2.3 A peak pulse current. |
| 2 | A | passive | Anode of the unidirectional TVS, the end opposite the cathode band; the device is rated 200 W peak pulse power (10x1000us) with a -55 to +150 °C junction range. |
