PLED Open LED Protectors

PLED Unidirectional Series

Description

The PLED Unidirectional Series (PLEDxUx Series) open

LED protectors provide an electronic switching shunt path

around a single LED that fails as an open circuit. This

ensures the remaining string of LEDs will continue to

function even though a single LED in the string has failed

open. It also provides reverse battery or reverse power

polarity protection.

The PLED Unidirectional Series components were

designed to enable higher reliability in outdoor LED lighting

applications such as street lighting, outdoor signage,

aircraft runway lighting, roadside warning lights and other

applications.

Compatible with one, two and three watt LEDs that have

a nominal 3V forward characteristic, PLED Unidirectional

Series components are available in two different surface

mount packages, the DO-214AA and the Quad Flat Pak No-

lead (QFN). The QFN’s low proﬁle, chip scale package (CSP)

is ideal for dense board applications.

Channel 1: current through LEDs (318 mA)

Channel 2: voltage across PLED device (4.5 V)

Channel 1: current through LEDs (346 mA) and PLED device once it is fully turned on 2.5 μsec later

Channel 2: voltage across PLED device (21.3 V before PLED crowbars with 2 V drop)

Note: These two graphs show the current magnitude through the LED string with and without the PLED included. There is no noticeable effect on the LED current magnitude when the

PLED is included in the circuit as compared to the LED current magnitude when the PLED is not in the circuit. (The conversion factor for the test measurement in the graphs above is

10mA/mV for the Pearson coil measurement, therefore, the current magnitude in the ﬁrst ﬁgure is 10mA*8.9 = 89mA, while the second ﬁgure is 91mA.)
