Application Field

The UB16BCT-E3/4W diode is used in various industries, from automotive to lighting and power conversion. In automotive industries it is used for its low reverse leakage, overload protection, and high power capabilities. The diode is also used in applications requiring soft switching and snubber circuits, such as power converters, motor drives, and domestic appliance control circuits. It is highly reliable and has a wide operating temperature range.

Working Principle

The UB16BCT-E3/4W diode has four terminals, with each terminal connected to one diode. The diode is used to regulate the current flow through the circuit by blocking the reverse current. When the forward voltage applied to the diode is greater than its reverse voltage, the diode becomes conductive and a current flows from the anode to the cathode. The anode is the positive side of the diode, and the cathode is the negative side. When a reverse voltage is applied or there is no voltage at all, the diode does not allow a current to pass and acts as an insulator.

The diode has a reverse breakdown voltage, otherwise known as peak inverse voltage or PIV, which is the maximum voltage that the diode can withstand in reverse bias without sustaining damage. It also has a forward voltage drop, otherwise known as forward voltage rating or FVR, which is the voltage at which the diode begins to conduct current. The UB16BCT-E3/4W diode has a PIV of 400V and an FVR of 1.0V.

The diode also has a power rating, which is the maximum power it can handle. The UB16BCT-E3/4W diode has a power rating of 3.2A at Tamb = 100°C and a reverse current rating of 200mA.

The UB16BCT-E3/4W is a very useful and reliable device for a variety of applications, from automotive to lighting control. Its low reverse leakage, overload protection and high power capability make it ideal for applications requiring soft switching and snubber circuits.
