Vishay Intertech · Pre-ordered Products · SOD-123

BZT52C36-E3-18 from Vishay Intertech, in a SOD-123. 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 of the Zener diode, marked by the cathode bar on the package; positive terminal in Zener (reverse) operation, with VZ 34.20 to 37.80 V (nom. 36 V) at IZT1 = 2 mA for BZT52C36.
2 A passive Anode of the Zener diode, the end opposite the cathode bar; Ptot is 500 mW max (300 mW on FR-4 with recommended footprint).
