Tak Cheong · Zener Diodes · LL-34
TCZM6V2BTR from Tak Cheong, in a LL-34. 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 terminal of the Zener diode, marked by the blue color band denoting negative polarity; the Zener voltage regulates in reverse bias with this pin positive (TCZM6V2B: VZ 6.08-6.32 V at IZT = 5 mA). |
| 2 | Anode | passive | Anode terminal of the Zener diode, opposite the cathode color band; forward voltage is 1 V maximum at IF = 100 mA. |
