# BZX84C33VLFHT116

**ROHM Semicon** · Zener Diodes · SOT-23

BZX84C33VLFHT116 from ROHM Semicon, in a SOT-23. 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 | Anode | passive | Anode of the Zener diode (pin 1 in the inner circuit diagram on page 1); for BZX84C33VLFH the Zener voltage is 31.00 V min to 35.00 V max at IZ = 2 mA. |
| 2 | N/C | unconnected | No internal connection; pin 2 is marked N/C in the inner circuit diagram. |
| 3 | Cathode | passive | Cathode of the Zener diode (pin 3 in the inner circuit diagram on page 1); power dissipation is limited to 250 mW on a glass-epoxy substrate. |
