MSESD5D3V3C

MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOD-523

MSESD5D3V3C from MSKSEMI, 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 A1 passive Bidirectional TVS terminal 1 (protected line side), 3.3 V max working voltage (VRWM), 200 W peak pulse power at 8/20 µs, ±15 kV air / ±8 kV contact IEC61000-4-2.
2 A2 passive Bidirectional TVS terminal 2 (second line or ground side), 3.3 V max working voltage (VRWM), 200 W peak pulse power at 8/20 µs, ±15 kV air / ±8 kV contact IEC61000-4-2.
