Protective current-limiting resistors may be necessary to operate the LEDs within the specified range. 2. LEDs mounted in parallel should each be placed in series with its own current-limiting resistor. 3. The driving circuit should be designed to protect the LED against reverse voltages and transient voltage spikes when the circuit is powered up or shut down. 4. The safe operating current should be chosen after considering the maximum ambient temperature of the operating environment. 5. Prolonged reverse bias should be avoided, as it could cause metal migration, leading to an increase in leakage current or causing a short circuit. PRECAUTIONARY NOTES 1.
