PLED9Q12 Description

Short technical summary and product information.

The PLED9Q12 is an open LED protector from Littelfuse's PLED series. It provides a switching electronic shunt path when an LED in a string fails as an open circuit, ensuring the remaining LEDs continue to function. This device is designed for higher reliability in outdoor LED lighting applications such as street lighting, signage, and aircraft runway lighting.

 

Key electrical specifications include a breakdown voltage range of 9V to 18V, minimum holding current of 5 mA, minimum switching current of 100 mA, and a maximum on-state current of 1.0 A with a maximum on-state voltage of 1.2 V at 1 A. The critical rate of rise of voltage is at least 250 V/µs. The device is compatible with PWM frequencies up to 30 kHz.

 

The PLED9Q12 is offered in a surface mount 2-QFN (3x3) package. It operates over a junction temperature range of -40°C to +150°C and has a storage temperature range of -65°C to +150°C. Thermal resistance varies by PCB configuration: 90°C/W on standard FR-4 and 40°C/W on aluminum PCB for DO-214 package; 120°C/W and 60°C/W for QFN on FR-4 and aluminum respectively. The device is RoHS compliant and halogen-free as stated in the datasheet.
