1SMA5924BT3G from onsemi, in a 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 | Cathode, identified by the polarity band on the SMA package (Style 1 pin 1), and the cathode is marked by a molded polarity notch or cathode band per the mechanical characteristics. |
| 2 | ANODE | passive | Anode, the forward-biased terminal, for which the datasheet specifies VF = 1.2 V max at IF = 200 mA for all types. |
