RCLAMP2451ZATFT

SEMTECH · ESD And Surge Protection (TVS/ESD) · 0201

RCLAMP2451ZATFT from SEMTECH, in a 0201. 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 PIN 1 passive One of two terminals of the bidirectional, electrically symmetrical 1-line ESD protection device; the datasheet specifies a 24 V reverse stand-off (VRWM) between pin 1 and pin 2 in either direction.
2 PIN 2 passive The other of two terminals of the bidirectional, electrically symmetrical 1-line ESD protection device; the datasheet specifies a 24 V reverse stand-off (VRWM) between pin 2 and pin 1 in either direction.

CAD (KiCad official)

  • Symbol: RCLAMP2451ZATFT
  • Footprint: Diode_SMD:D_0201_0603Metric
  • 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal 01005 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: rclamp2451zatft-etched.step / rclamp2451zatft-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rclamp2451zatft.step / rclamp2451zatft.glb are the bare package body.
