PTZTE256.8B-MS

MSKSEMI · Zener Diodes · SMA(DO-214AC)

PTZTE256.8B-MS from MSKSEMI, 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 color band on the package; for PTZTE256.8B-MS the Zener voltage is 6.8 V min and 7.70 V max at IZT = 40 mA, with PD up to 1.0 W.
2 A passive Anode, the end opposite the color band; Zener voltage is measured at the cathode with respect to this pin.
