WebLED with series diode fed from AC supply. This circuit will work for low AC voltages. The problem is that diodes and LEDs have reverse leakage current. The one with the higher leakage will cause the other to experience more than its fair share of the applied AC voltage. If this exceeds the reverse breakdown of the LED then it may perish.

WebA bulb-shaped modern retrofit LED lamp with aluminum heat sink, a light diffusing dome and E27 screw base, using a built-in power supply working on mains voltage. A light-emitting diode ( LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy ... WebThe LEDs do conduct some very low current even with only two volts or less across them - they may appear as resistors of a few megohms. …

Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical. WebSchottky diodes constructed from silicon carbide have a much lower reverse leakage current than silicon Schottky diodes, as well as higher forward voltage (about 1.4–1.8 V …

WebTVS Diodes are silicon avalanche devices typically chosen for their fast response time (low clamping voltage), lower capacitance and low leakage current.
