BZM55C3V6-TR

Vishay Intertech · Zener Diodes · SOD-80

BZM55C3V6-TR from Vishay Intertech, in a SOD-80. 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 cathode band; it goes positive in reverse (Zener) operation, where BZM55C3V6 regulates at VZ 3.4 to 3.8 V (3.6 V nom.) at IZT1 = 5 mA with Ptot of 500 mW max.
2 A passive Anode, the end without the cathode marking; in forward conduction VF is 1.5 V max at IF = 200 mA.
