BA158GHR1G is a single phase, 4A, 400V silicon rectifier diode, which can be used in variety of place for noise filtering and power rectification. This diode is mainly used for dc-dc rectification, power supplies, motor speed control and rectification for other DC equipment, and can also be used for power filtering, to reduce the normal ripple and noise.Working principle of a BA158GHR1G rectifier diode is is complicated but not hard to understand. A regular diode is made from two pieces of doped semiconductor, namely anode and cathode and a junction between the two. When we apply a voltage of minimum 0.7v across the diode (which is called the forward voltage), electrons flow from the anode to the cathode, creating a flow of electric current. This is called forward bias and the diode is then said to start conducting. The current flow must obey Ohm\'s law and the diode\'s resistance is nonlinear and follows the Shockley equation.The BA158GHR1G rectifier diode has a push-pull principle that makes it different from regular silicon diodes. In this case, when a reverse bias is applied and the voltage across the diode is negative, the outer P-type and the inner N-type sides of the diode are also negatively charged. As the voltage continues to increase, the negative charge on the inner N-type side shrinks and the positive charge on the outer P-type side swells, causing the junction to break down and causing, eventually, a visible hole in the junction. This allows the current to flow in a reverse direction, making the diode act like a conductor. The P-N junction begins to show resistance until the current reaches zero and breaks down again, this is the essence of the push-pull cycle.The BA158GHR1G rectifier diode is highly efficient and robust and can be used in many applications such as for motor speed control, power supplies, dc-dc conversion and general power electronics applications. It is commonly used in power rectification and switching devices, to reduce the normal ripple caused in power transmissions and reduce the noise in the system. The BA158GHR1G is also great for making inrush current limiting devices, for limiting the power consumed by switching power supplies, and for creating clamp devices for protecting other components from voltage surges.In conclusion, the BA158GHR1G is a single phase, 4A, 400V rectifier diode and can be used in many places. Its push-pull cycle principle and high performance make it ideal for rectification and power conversion applications. Its ability to withstand voltage surges and ripple makes it great for noise filtering and inrush current limiting. All these features make the BA158GHR1G an ideal solution for many of your power rectification and power filter needs.
