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 “light up” and Vf of the suspect LEDs at low currents.

The Vf of “good” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP

product.
