1.5KE11A R0G from Taiwan Semiconductor(Taiwan Semicon), 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 | K | passive | Cathode, the end marked with the cathode band on this unidirectional device (1.5KE11A: VWM 9.40V, VBR 10.5V to 11.6V at 1.0mA, VC 15.6V max at IPPM 100A). |
| 2 | A | passive | Anode, the end without the cathode band on this unidirectional device; connect to the lower-potential side for forward-biased clamping (VF 3.5V max at 50A). |
