SP3021-01ETG

Littelfuse · ESD Protection Devices · SOD-882

SP3021-01ETG from Littelfuse, in a SOD-882. 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 One terminal of the back-to-back bidirectional TVS diode pair, which provides symmetrical ESD protection rated at ±8kV contact and ±15kV air per IEC 61000-4-2 with 5.0V reverse standoff voltage and 0.5pF diode capacitance at 0V bias.
2 2 passive The other terminal of the back-to-back bidirectional TVS diode pair, which provides symmetrical ESD protection rated at ±8kV contact and ±15kV air per IEC 61000-4-2 with 5.0V reverse standoff voltage and 0.5pF diode capacitance at 0V bias.
