The LLDB3 electronic part manufactured by CDIL is a diac, also known as a diode for alternating current. It features an Ifmax rating of 2A and MiniMELF technology. It has a voltage range of 28-36V. This part is designed for use as a triggering device in AC circuits, such as capacitive power supplies, relay logic networks, and motor control circuits. It acts as a switch, controlling when and how much voltage is allowed to travel across the circuit, and can be used in conjunction with thyristors, triacs, and solid state relays. It is commonly found in household and industrial appliances, such as air conditioners, washing machines, elevators, lighting systems, and door openers.
