ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward

voltage, or “ no lightup ” at low currents.

To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents.

The Vf of “ good ” LEDs should be >2.0V@0.1mA for InGaN product
