# 1.5KE82A

**Littelfuse** · ESD And Surge Protection (TVS/ESD) · DO-201

1.5KE82A from Littelfuse, in a DO-201. 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 | Color-band end of the axial lead, which the datasheet says denotes the cathode on uni-directional products; the datasheet gives no pin-specific electrical limit for this lead. |
| 2 | Anode | passive | Non-banded axial lead of the uni-directional 1.5KE82A, shown as the anode in the functional diagram; the datasheet gives no pin-specific electrical limit for this lead. |
