KESD0805

KUU · Varistors · 0805

KESD0805 from KUU, in a 0805. 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 1 passive Terminal electrode (Ag/Ni/Sn) of the bidirectional chip varistor, interchangeable with the other terminal, 27 VDC / 20 VAC max working voltage, 36 V ±10% varistor voltage at 1 mA, 60 V max clamping at 8/20 µs 1 A.
2 2 passive Terminal electrode (Ag/Ni/Sn) of the bidirectional chip varistor, interchangeable with the other terminal, 100 A peak current (8/20 µs), 0.3 J energy (10/1000 µs), 210 pF typical at 1 MHz.
