Notes:

Parameter is guaranteed by design and/or device characterization.

This PLED5 Open LED Protector device provides three

methods for increasing the reliability of LED lighting:

1) If one of the LEDs in an array fails open, this device

provides a substitute electronic path so that the string

continues to function

2) It protects against ESD events up to ± 8 kV for contact

discharges and ± 15 kV for air discharges per the IEC

61000-4-2 electrostatic immunity standard.

3) It provides protection in the case of accidental reverse

battery or power connection.

High reliability of lighting functions such as trafc lighting,

aircraft lighting, advertising lighting, and runway lighting

demand the use of a device such as the PLED5.

Littelfuse offers over current devices for implementation in

power circuits that can also enhance the reliability of circuit

operation. Our full line of circuit protection products can be
