# TC3V6TB

**Tak Cheong** · Zener Diodes · DO-35

TC3V6TB 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 | CATHODE | passive | Cathode terminal, identified by the polarity band on the glass body; the datasheet gives no pin-specific limits, so the device ratings apply (500 mW power dissipation, operating junction temperature +175 °C). |
| 2 | ANODE | passive | Anode terminal, the lead opposite the cathode band; the datasheet gives no pin-specific limits, so the device ratings apply (500 mW power dissipation, operating junction temperature +175 °C). |
