Features:
- Electronic shunt/bypass for open LEDs
- Reverse battery/power protection
- Fast switching
- Automatically resets after power cycle
- RoHS compliant
PLED Ultra Low Holding Current
The PLED ultra-low holding current series features a low holding current parameter that makes it compatible with LED lighting strings.
Features:
- Available in low profile, standard DO-214AA packages
- Fast switching
- RoHS compliant and halogen-free
- Automatically resets after power cycle
- Compatible with industrial lighting environments
- IEC-61000-4-2 ESD 30kV (Air), 30kV (contact)
- ESD protection of data lines in accordance with IEC 61000-4-4 (IEC801-2)
PLED 5 QFN
The PLED5 protector provides three methods of increasing the reliability of LED lighting, if one of the LEDs in an array fails open, this device provides a substitute electronic path so that the array continues to function.
Features:
- Reverse battery/power protection
- Surge capability > 24A
- Fast Switching
- Resets after power cycle
- Low turn-on (trigger voltage)
- Ideal for MR16, PAR type lamps
- Open LED bypass up to 500Ma
- ESD, IEC 61000-4-2 ±8kV contact, ±15 kV air
- EFT, IEC 61000-4-4, 40A(5/50nS)
PLEDxS-A
This automotive PLED series provides a switching electronic shunt path when an LED in an LED string fails as an open circuit. Ensuring the remaining string of LEDs will continue to function if a single LED does not.
Features:
- AEC-Q101 qualified and PPAP capable
- Available in standard DO-214AA package
- Compatible with industrial lighting environments
- IEC-61000-4-2 ESD 30kV (Air), 30kV (Contact)
- Fast switching
- Automatically resets after power cycle
- ESD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2)
- Compatible with PWM frequencies up to 30kHz
PLEDxUx-A
The automotive PLED Unidirectional series (PLEDxUx-A) open LED protectors provide a switching electronic shunt path around a single LED that fails as an open circuit, ensuring the remaining string of LEDs will continue to function even though a single LED in the string has failed open.
Features:
- AEC-Q101 qualified and PPAP capable
- Reverse battery/power protection
- Fast switching
- Automatically resets after power cycle
- Available in standard DO-214AA package
- Compatible with industrial lighting environments
- IEC-61000-4-2 ESD 30kV (Air), 30kV (Contact)
- ESD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2)
- Compatible with PWM frequencies up to 10kHz
PLEDxUSxA
PLEDxUSxA open LED protectors provide an electronic switching shunt path when an LED in an LED string fails as an open circuit. The components are designed to enable higher reliability in indoor LED lighting applications such as advertisement lighting and other applications.
This series is compatible with one, two or three watt LEDs that have a nominal 3V forward characteristic and is available in an SMB surface mount package. The DO-214AA (SMB) low profile package is ideal for dense board applications.
Features:
- Ideal for protecting high brightness LED with high operating current at specified condition
- Fast switching
- Reverse battery/power protection
- Compatible with industrial lighting environments
- IEC-61000-4-2 ESD 30Kv (Air), 30kV (Contact)
- RoHS complaint and halogen-free
