TC15VTB from Tak Cheong, in a DO-35. 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, the lead marked by the polarity band on the DO-35 axial glass body; it goes positive relative to the anode in zener (reverse) operation (TC15V: VZ 15 V nominal at IZT = 5 mA). |
| 2 | A | passive | Anode, the lead opposite the polarity band on the DO-35 axial package; forward voltage is 1.2 V max at IF = 200 mA. |
