# ER2D-LTP

**MCC(Micro Commercial Components)** · Diodes - Fast Recovery Rectifiers · DO-214AA(SMB)

ER2D-LTP from MCC(Micro Commercial Components), in a DO-214AA(SMB). 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, the terminal at the end of the SMB (DO-214AA) body carrying the Cathode Mark; the ER2D-L blocks 200V DC reverse voltage (200V peak repetitive, 140V RMS) and carries 2.0A average forward current at TL=110°C. |
| 2 | A | passive | Anode, the terminal opposite the Cathode Mark on the SMB (DO-214AA) body; forward voltage is a maximum of 0.95V at IFM=2.0A for the ER2A-L to ER2D-L and reverse recovery time is a maximum of 35ns. |
