CDST-70-G

Comchip · Switching Diodes · SOT-23

CDST-70-G from Comchip, 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 A1 passive Anode of the first diode; the CDST-70 circuit diagram shows two diodes with a common cathode at pin 3 (reverse voltage 70 V, forward current 200 mA).
2 A2 passive Anode of the second diode; the CDST-70 circuit diagram shows two diodes with a common cathode at pin 3 (reverse voltage 70 V, forward current 200 mA).
3 K passive Common cathode of both diodes in the CDST-70 circuit diagram (reverse voltage 70 V, forward current 200 mA per the datasheet).

  • Symbol: CDST-70-G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cdst-70-g-etched.step / cdst-70-g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cdst-70-g.step / cdst-70-g.glb are the bare package body.

Provenance

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

  • Datasheet: Comchip datasheet (4 pp, sha256 e85d69537d86e1f8, retrieved 2026-10-21, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-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).
