SZBZX84C9V1ET1G
onsemi · Zener Diodes · SOT-23
SZBZX84C9V1ET1G from onsemi, 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 terminal of the Zener diode; the datasheet gives no separate pin-level electrical limits for this pin beyond the device maximum ratings. |
| 2 | NC | unconnected | No internal connection (marked 'No Connection' in the Style 8 package outline and in the Electrical Characteristics pinout note). |
| 3 | CATHODE | passive | Cathode terminal of the Zener diode, indicated by the polarity band on the package; the datasheet gives no separate pin-level electrical limits for this pin beyond the device maximum ratings. |
