1.5KE200ARL

STMicroelectronics · TVS · DO-201

1.5KE200ARL from STMicroelectronics, 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 of the unidirectional Transil (1.5KE200A, VBR 190-210 V at 1 mA, VRM 171 V, 1500 W 10/1000 µs peak pulse power), connected to the positive/protected line.
2 A passive Anode of the unidirectional Transil (1.5KE200A), connected to the return/ground side; forward conduction is limited by IFSM of 200 A for 10 ms.
