LED bypass protection

The LBP01 series are bypass switches to be connected in parallel with 1 or 2 LEDs. In case of LED failure, this allows the current to flow through the other LEDs.

It also provides an overvoltage protection against surges defined in IEC 61000-4-2 and IEC 61000-4-5

Their robust dice also protect LEDs against surge.

These devices are compatible with LEDs up to 1 A.

LBP01 are packaged either in SMB or SOT23-5L
