TLZ5V1B-GS08

Vishay Intertech · Zener Diodes · SOD-80

TLZ5V1B-GS08 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, marked by the cathode identification band on the MiniMELF body; the Zener diode conducts at VZ (4.94 to 5.2 V at IZT1 = 20 mA for TLZ5V1B) when reverse biased with this pin positive.
2 A passive Anode of the single Zener diode; maximum forward voltage is 1.5 V at IF = 200 mA.
