ROHM Semicon · Zener Diodes · SOD-123FL
KDZVTR5.1B from ROHM Semicon, in a SOD-123FL. 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, marked by the bar on the package; Zener voltage VZ is 5.100 to 5.700 V at Iz = 40 mA, with IR max 20 µA at VR = 1.0 V. |
| 2 | A | passive | Anode; power dissipation is limited to 1000 mW and junction temperature to 150 °C. |
