FFSH20120A-F085

Diodes - Rectifiers - Single

The FFSH20120A-F085 is a single diode rectifier used to convert an AC current into a DC current. This type of diode is typically used in audio amplifier circuits, solar inverters, welding machines, and rectifiers for power supplies. It has a peak reverse voltage (VRRM) of 200V, a continuous forward current (IF) of 8.5A, and a reverse current (IR) of 75uA. This device is available in a TO-220AB package.

A single diode rectifier works by using an electrically active region between two electrodes, typically referred to as an anode and cathode. When voltage is applied to the diode, the anode becomes positively charged, while the cathode becomes negatively charged. Current is then able to flow in one direction, from the anode to the cathode. This is known as forward-biased behavior. Reversing the voltage will cause the rectifier to become reverse-biased, blocking any current from flowing.

The FFSH20120A-F085 is a single phase rectifier, meaning it can be used to convert a single-phase AC current into a DC current. When a single-phase AC current is applied to the device, the diode will only conduct during the positive half-cycle of the current. During the negative half-cycle, the current will flow through the diode in the opposite direction, resulting in a pulsating DC current. To obtain a smoother DC current, two or more single diode rectifiers can be connected in parallel in a diode bridge configuration.

The FFSH20120A-F085 has a surge rating of 130A, meaning that it can handle higher transient surges of current without suffering damage. This is especially useful in solar inverters, as they are subject to high current surges when a cloud passes in front of the sun. The device also has a low reverse current leakage rating of 75uA, meaning that it won’t draw any current when reverse-biased. This is important in power supplies, as it ensures that the power supply won’t be drained when the input voltage is removed.

The FFSH20120A-F085 is an effective device for converting AC currents into DC currents in a wide range of applications. Its high surge rating and low reverse current leakage make it ideal for applications such as audio amplifiers, solar inverters, welding machines, and power supplies. The device is available in a TO-220AB package, making it easy to integrate into existing circuit designs.
