FERD20H100SB-TR Discrete Semiconductor Products

Diodes - Rectifiers - Single

The FERD20H100SB-TR is a single rectifier diode rated for a maximum average forward current of 20A and a maximum reverse voltage of 100Volts. Diodes are a commonly used electrical component in all sorts of applications. These versatile rectifier diodes can be used for a variety of different uses, such as providing protection against reverse voltages, or for rectifying electrical signals for use in analog-digital converters and other circuits. They can also serve as a limiter in circuits or as a voltage follower.

Functionality

The FERD20H100SB-TR is composed of a small p-n junction, in which an n-type semiconductor is sandwiched between two p-type semiconductors. When the diode is forward biased, the junction allows current to pass through. This causes the voltage drop across the junction to be very small, and allows a large current to be carried. When the diode is reverse biased, it becomes a nonconducting device, with the junction differences blocking any potential current.

Application Field

The FERD20H100SB-TR is commonly used in applications such as motor controls and AC-DC power supplies. In motor controls, the diode can be used as part of the power drive circuitry, with one diode being responsible for rectifying the AC signal driving the motor, and the reverse-biased diode providing protection from back-electromotive forces. In DC power supplies, the diode can be used to provide rectification or protection from short-circuit current or reverse voltage.

Working Principle

The working principle for the FERD20H100SB-TR is essentially the same as for all rectifier diodes. When the diode is forward biased, it acts as a low impedance current path, allowing large amounts of current to pass through with low voltage drop. When reverse biased, the diode essentially behaves like an open circuit, with no current passing through. This property allows the diode to both rectify and limit the voltage or current in a circuit.

Conclusion

The FERD20H100SB-TR is a versatile rectifier diode that can be used in a wide range of applications, as it can both rectify and limit voltages and currents. It is suitable for use in motor controls, AC-DC power supplies, as voltage followers and much more. With its low voltage drop, it can be easily integrated into many different circuit designs.
