TPAZ5123-01H

TECH PUBLIC · ESD Protection Devices · SOD-523

TPAZ5123-01H from TECH PUBLIC, in a SOD-523. 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 Terminal 1 (bidirectional TVS) passive One of the two terminals of the bidirectional TVS diode, rated for a reverse working voltage of 3.3 V max and a peak pulse current of 9 A (8/20 µs).
2 Terminal 2 (bidirectional TVS) passive The other terminal of the bidirectional TVS diode, which clamps across the same ±3.3 V working range as pin 1 and is rated for ESD of ±30 kV contact and air per IEC 61000-4-2.
