GF1DHE3/67A

Diodes - Rectifiers - Single

A single rectifier diode is an electronic device that allows current to flow in the forward direction while blocking any current that flows in the reverse direction. This type of diode is commonly used in a variety of applications that require the electrical signal to flow in just one direction. One example of such an application is the GF1DHE3/67A, a single rectifier diode from Renesas. This diode is designed for use in automotive, consumer, and communication applications.

GF1DHE3/67A Application Field

The GF1DHE3/67A is designed for use in medium power circuits, specifically automotive and consumer applications. The device can be used to rectify AC signals and is commonly employed in audio circuits, voltage regulators, and in switching power supplies. Due to its higher current and power ratings, the GF1DHE3/67A is also suitable for various communication applications, such as mobile communications and telecom equipment. Its low forward voltage drop and reverse current leakage make it a great performer in these applications.

GF1DHE3/67A Working Principle

The GF1DHE3/67A is a forward-biased rectifier diode that passes the electrical current in the forward direction while blocking the current flow in the reverse direction. This diode has a maximum reverse voltage of ∼160 volts, a peak reverse voltage of ∼200 volts, and a maximum forward voltage of ∼900 mV. The forward and busy current ratings of the device are given in datasheets and range from 1.5 A to 5 A, respectively.

The forward voltage drop of the diode is typically between 700 mV and 800 mV when operating at a current of 3 A. This device also has a capacitance of 4 pF when the reverse voltage is  0V, which helps minimize power loss in low-frequency signals. Finally, the reverse current leakage of the diode is very low, with a maximum of 15 nA.
