S4PJHM3/86A

Diodes - Rectifiers - Single

S4PJHM3/86A is a kind of single rectifier diode which is widely used in the electronics industry. It is a two-terminal, solid-state device that can be used as a switch in electronic circuits. Basically, it can switch current flow in a circuit in a single direction. It has various features such as fast switching, high blocking voltage, and reliable operation. The rectifier diode provides simple and cost-effective ways of converting a single-phase AC supply into a DC supply.

Application Field

The S4PJHM3/86A is widely used in many applications, including the power supply circuit, low-power converter, display driver circuit, and high-frequency current limiting. It is often used in the manufacture of consumer electronics and automotive components.

In the power supply circuit, the rectifier diode can convert an AC voltage into a DC voltage. This is done by using the diode’s junction to switch the current flow in only one direction. It can also provide a switching effect in DC circuits by controlling the voltage level of its output. The diode is also used in the low-power converter, where it is used to reduce the current level to a needed lower level.

In display driver circuit applications, the rectifier diode is used for reducing the switching frequency of the circuit. It can also help eliminate noise generated by the display driver circuit. Moreover, the diode can be used in the high-frequency current system to limit the amount of current passing through it.

Working Principle

The S4PJHM3/86A rectifier diode is a p-n junction, formed by combining the N-type semiconductor material, the silicon substrate, and the P-type material. This junction forms the diode’s junction region. When a voltage is applied across the diode, it creates a potential difference between the N and P regions and this induces a current flow through the diode.

When a negative voltage is applied across the diode, the current will pass through it in the conventional forward direction. This is because the P-type material is more positive than the N-type material and the electrons can easily flow from the N-type to the P-type. However, when a positive voltage is applied across the diode, the current will not be able to flow through it. This is because the N-type material is more positive than the P-type and the electrons are repelled.

This is why the S4PJHM3/86A rectifier diode is referred to as a "one-way valve". This is because the voltage applied to the diode will determine the direction in which the current flows. This makes the rectifier diode an effective way of regulating and controlling the current flow in an electronic circuit.
