# ER5JC

**DIYI Elec Tech** · Fast Recovery / High Efficiency Diodes · SMC

ER5JC from DIYI Elec Tech, in a SMC. 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, marked by the color band on the package; ER5JC blocks VRRM 600 V and carries IF(AV) 5.0 A at TL=75°C. |
| 2 | A | passive | Anode terminal, the end opposite the color band; forward voltage is 1.3 V at IF=5A for the ER5JC. |

## CAD (KiCad official)

- Symbol: `ER5JC`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC (KiCad packages3D, STEP)
- 3D model files: `er5jc-etched.step` / `er5jc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `er5jc.step` / `er5jc.glb` are the bare package body.
