BAV170/ZLR Application Field and Working Principle

The BAV170/ZLR diode array from NXP Semiconductors is a four-channel back-to-back diode array. This diode array is typically used in applications such as direct current blocking, overvoltage protection, and AC lamp control.

Features

The BAV170/ZLR diode array includes various features to make it ideal for many applications. It has an operating temperature range of -55°C to +150°C, a forward current rating of 100mA, and a reverse current rating of 5mA. The forward voltage drop is only 0.38V at a forward current of 10mA. This diode array uses NXP Semiconductors\' patented Epitaxial Substrate Layout, which reduces on-state resistance and storage time. This diode array also features an integrated ESD protection and it is RoHS compliant.

Application Field

The BAV170/ZLR diode array is commonly used in applications such as direct current blocking, overvoltage protection, and AC lamp control. For example, in AC lamp control, it can be used to prevent accidental lamp switching in the presence of alternating current. This diode array can also be used for protection against reverse battery connection, when two batteries are connected in series.

Working Principle

The BAV170/ZLR diode array operates on the principle of a diode\'s ability to block voltage and allow current flow in only one direction. The four channels of the diode array are connected in a back-to-back configuration, which provides a bridge between two lines. When an AC voltage is applied, each pair of diodes will conduct current in opposite directions, allowing the AC voltage to pass through the diode array.

When a DC voltage is applied, the diode array will block any current flow in the reverse direction. The reverse voltage protection also prevents any voltage spikes or overvoltage conditions from damage the components connected to the diode array. The low forward voltage drop and low on-state resistance of the BAV170/ZLR diode array helps to ensure that the AC or DC voltage will not be affected by the diode array.

Conclusion

The BAV170/ZLR diode array from NXP Semiconductors is an ideal diode array for application such as direct current blocking, overvoltage protection, and AC lamp control. This diode array has an operating temperature range of -55°C to +150°C and it is RoHS compliant. It operates on the principle of a diode\'s ability to block voltage and allow current flow in only one direction and it features low forward voltage drop and low on-state resistance to ensure that the AC and DC voltage will not be affected by the diode array. The BAV170/ZLR diode array can be used in a variety of applications and it is an excellent choice for providing reliable protection against reverse battery connection, overvoltage conditions, and AC lamp control.
