PTZTE255.1B

ROHM Semicon · Zener Diodes · SMA(DO-214AC)

PTZTE255.1B from ROHM Semicon, in a SMA(DO-214AC). 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 marking bar on the package; the Zener voltage VZ is 5.100 V min to 5.700 V max at 40 mA.
2 A passive Anode, identified on the package by the direction of the marking bar; the part dissipates up to 1000 mW (PD).
