MSKSEMI · Zener Diodes · SMA
PTZ33B-MS from MSKSEMI, in a SMA. 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, the end marked by the color band; the Zener voltage VZ of the PTZ33B-MS is 33.0 V min, 34.95 V typ and 37.0 V max at 10 mA test current. |
| 2 | A | passive | Anode terminal; the device is rated for 1.0 W power dissipation and 150 °C junction temperature. |
