SESD0402X1BN-0010-098

Littelfuse · ESD And Surge Protection (TVS/ESD) · 0402

SESD0402X1BN-0010-098 from Littelfuse, in a 0402. 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 of the two bidirectional ESD protection terminals of the single channel, rated for a reverse working voltage of ±9.00 V (min/max), 0.10 pF typical input capacitance at 0 V and 3 GHz, and a maximum reverse leakage of 50 nA at 5 V.
2 2 passive The other bidirectional ESD protection terminal of the single channel, with the same limits as pin 1: ±9.00 V reverse working voltage, 0.12 pF maximum input capacitance, and 50 nA maximum leakage at 5 V.
