# 1N4002-TP

**MCC(Micro Commercial Components)** · Diodes - General Purpose · DO-41

1N4002-TP from MCC(Micro Commercial Components), in a DO-41. 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 | Cathode | passive | The cathode is the end marked by the cathode band on the DO-41 body, and for the 1N4002 the rated peak reverse voltage is 100 V (DC blocking 100 V) with 1.0 A average forward current at TA = 75°C. |
| 2 | A | passive | The anode is the unmarked lead opposite the cathode band; the datasheet does not name it explicitly, so its identity is inferred from the cathode mark. |
