PLED18Q12 Description

Short technical summary and product information.

The PLED18Q12 is part of Littelfuse's PLED Series of open LED protectors. These devices provide a switching electronic shunt path when an LED in a string fails as an open circuit, ensuring the remaining LEDs continue to function.

 

Key electrical specifications include a minimum breakdown voltage of 18V, minimum off-state voltage of 33V, minimum holding current of 5mA, and minimum switching current of 100mA. The maximum on-state current is 1A with a maximum on-state voltage of 1.2V at 1A. The device supports PWM frequencies up to 30kHz and has a critical rate of rise of off-state voltage of 250V/µs.

 

The PLED18Q12 is available in a surface-mount package (2-TDFN / 2-QFN 3x3mm) and operates over a junction temperature range of -40°C to +150°C. Thermal resistance is 120°C/W on standard FR-4 PCB and 60°C/W on aluminum PCB. It is RoHS-compliant and halogen-free.
