1.5KE11A R0G

Taiwan Semiconductor(Taiwan Semicon) · TVS · DO-201

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).
