PESD0603MS03-MS

MSKSEMI · ESD And Surge Protection (TVS/ESD) · 0603

PESD0603MS03-MS from MSKSEMI, in a 0603. 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 ESD protection terminal, one side of the single-line TVS (continuous operating voltage 3.3 V max, 0.05 pF typ. capacitance); the device is symmetric so terminals are interchangeable.
2 A2 passive Bidirectional ESD protection terminal, other side of the single-line TVS (continuous operating voltage 3.3 V max, IEC 61000-4-2 rated 8 kV contact / 15 kV air); the device is symmetric so terminals are interchangeable.
