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. |

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)
