Vishay Intertech · TVS · DO-27
1.5KE100A-E3 from Vishay Intertech, in a DO-27. 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 lead, marked by the color band on the unidirectional 1.5KE100A (VBR 95.0 V to 105 V at 1.0 mA, VWM 85.5 V). |
| 2 | A | passive | Anode lead at the end with no band; the 1.5KE100A has a maximum clamping voltage of 137 V at IPPM 10.9 A (10/1000 µs). |
