1.5KE68A
SMC(Sangdest Microelectronicstronic (Nanjing)) · TVS · DO-201AD
1.5KE68A from SMC(Sangdest Microelectronicstronic (Nanjing)), in a DO-201AD. 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, marked by the cathode band or notch; for the unidirectional 1.5KE68A it takes the positive side with a 58.1 V reverse stand-off voltage, 64.6 to 71.4 V breakdown at 1 mA, and 92 V maximum clamping at 16.5 A peak pulse current. |
| 2 | A | passive | Anode, the end without the cathode band; it connects to the negative side or ground of the protected line, and the part is rated for 1500 W peak pulse power (10x1000 µs). |
