CMPSH-3E TR PBFREE

Central Semicon · Schottky Barrier Diodes (SBD) · SOT-23

CMPSH-3E TR PBFREE from Central Semicon, in a SOT-23. 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 Anode passive Anode terminal of the CMPSH-3E single Schottky diode, rated for a peak repetitive reverse voltage VRRM of 40 V and a continuous forward current of 200 mA.
2 No Connection unconnected Lead 2 is listed as no connection and is not connected to the diode.
3 Cathode passive Cathode terminal of the CMPSH-3E single Schottky diode, with a minimum reverse breakdown voltage BVR of 40 V at IR=100µA.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin 1. If requesting Tin/Lead plated devices, add the suffix “ TIN/LEAD” to the part number when ordering (example: 2N2222A TIN/LEAD). 5

CAD (KiCad official)

  • Symbol: CMPSH-3E TR PBFREE
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0050000000000001 mm tall, datasheet A, midpoint of min and max). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: cmpsh-3e-tr-pbfree-etched.step / cmpsh-3e-tr-pbfree-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmpsh-3e-tr-pbfree.step / cmpsh-3e-tr-pbfree.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Central Semicon datasheet (5 pp, sha256 91fa9efeaef73f04, retrieved 2026-11-12, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
