ESD7551N2T5G

TECH PUBLIC · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

ESD7551N2T5G from TECH PUBLIC, in a DFN1006-2. 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 bidirectional TVS diode, which clamps ESD and surge transients and has a reverse working voltage of 3.3 V max and a breakdown voltage of 3.6 V min at 1 mA.
2 2 passive The other terminal of the bidirectional TVS diode, which clamps ESD and surge transients and is rated for ±20 kV air and ±15 kV contact discharge per IEC 61000-4-2.
