BAV19W-HE3-18 is a silicon, surface mount power rectifier diode. It is designed specifically for rectifying higher current loads and offers high reliability in arduous switching conditions. The BAV19W-HE3-18 diode is capable of supplying over 6 amperes of current, making it one of the most powerful single diodes available.

Application Field

The BAV19W-HE3-18 is commonly used in a variety of applications including DC to AC converters, AC to DC rectification circuits, electronic lighting ballasts, AC motor speed control circuits, solid-state switches, and automotive circuit protection.

Working Principle

The BAV19W-HE3-18 diode operates using the principle of rectification, which is the process of converting alternating current (AC) electricity into direct current (DC) electricity. In a rectifier circuit, the current can only flow in one direction, and is blocked in the other.

Thus, the BAV19W-HE3-18 gives protection from transient voltage spikes by preventing the flow of current into the sensitive electronic equipment.

Rectification is the process of converting AC power, which alternates between positive and negative voltages, into DC power, which is a constant voltage. In a full-wave rectifier circuit, the alternating current is converted into pulsating DC by means of two diodes that are connected in opposite directions. The one diode will conduct current in one direction while the other will conduct in the opposite direction.

When the input AC voltage is greater than the voltage across the diode, current will flow through the diode and the output will be a series of pulses that represent the amplified and rectified AC signal. By using four or more diodes, the BAV19W-HE3-18 diode can create full-wave rectification, which further minimizes the amount of ripple present in the output voltage and makes it more suitable for powering loads.

The BAV19W-HE3-18 also offers protection from over-voltage and transient voltage spikes by preventing the flow of current into the sensitive electronic equipment. This makes the diode highly suitable for use in power supply circuits, where continuous and stable DC output is required.
