The VS-88HFR20 is classified as a diode rectifier and is a single phase rectifier. This semiconductor device is produced by Vishay Semiconductors and is part of the RR series of rectifiers. It is a Schottky rectifier, which features low forward voltage drop, fast switching speed, and low power consumption.

The VS-88HFR20 is designed with an oxide passivated mesa structure and has a total power dissipation of 1.0 watts at a forward current of 8.0 Amperes and an operating temperature range of -55 to +150 degrees Celsius. It is housed in a through-hole TO-220 package and the contact material is soft solder alloy, with a 1.3mm maximum lead diameter.

The device has a breakdown voltage of 800V and a forward voltage of 1.07V at 8A. The reverse current leakage is maximum 1.0 μA at 25°C, and an average of 0.175 μA at 125°C. There is a reverse recovery time of typically <25ns.

The maximum peak repetitive reverse voltage is 800V and the surge peak forward current is 10A. The device is RoHS Compliant and has UL recognition.

The main application field for the VS-88HFR20 is in computing, power supplies and Uninterrupted Power Supplies (UPS), as it is well suited for use in high frequency circuit rectification. Such circuits include a step-down power supply and a full-wave rectification circuit.

The working principle of the VS-88HFR20 is fairly simple. The device consists of two metal plates, one positive and one negative, connected to a semiconductive material. When a voltage is applied across the positive and negative plates, electrons flow from the negative plate toward the positive plate, creating a current. This current is what is used to power the circuit or device.

The device also has a reverse characteristic, where the current flows from the positive plate to the negative plate in the opposite direction when certain conditions are met. This reverse current can be used to protect the device from over-voltage or to protect other connected circuits from over-voltage.

To summarize, the VS-88HFR20 is a single phase rectifier that is used in a variety of applications. It features a low forward voltage drop, fast switching speed, and low power consumption. It is suitable for circuit rectification, power supplies, and other purposes such as over-voltage protection. In its simplest form it consists two metal plates connected to a semiconductor material, which when a voltage is applied across it, produces a current which can be used to power the device.
