SMAJ16AHE3_A
Vishay Intertech · TVS · SMA(DO-214AC)
SMAJ16AHE3_A from Vishay Intertech, 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 | K | passive | Cathode terminal, marked by the cathode band on uni-directional types such as the SMAJ16A (VWM 16 V, VBR 17.8 V to 19.7 V at 1.0 mA). |
| 2 | A | passive | Anode terminal at the end opposite the cathode band, and it is the second terminal of the 2-terminal SMA package. |
