# PMEG4010BEA

**Nexperia** · Schottky Diodes · SOD-323

PMEG4010BEA from Nexperia, in a SOD-323. 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 | K | passive | Cathode of the Schottky barrier rectifier; the cathode tab is the soldering point referenced for the junction-to-solder-point thermal resistance Rth(j-sp) of 210 K/W maximum. |
| 2 | A | passive | Anode of the Schottky barrier rectifier; the datasheet gives no anode-specific limit, so the device limiting values in Table 5 (for example VR = 40 V and IF = 1 A at Tsp ≤ 55 °C) apply to the part as a whole. |
