1N5804US

Diodes - Rectifiers - Single

The 1N5804US diode is single-phase, ultra-fast recovery, glass-passivated Schottky rectifier with an anode-cathode voltage of 2400V and a maximum surge peak repetitive current of 8A. This type of rectifier is suitable for a wide range of applications such as reverse voltage protection, DC power supplies, automotive electronics, and more.

Application Field

The 1N5804US diode is designed for use in applications such as reverse voltage protection and DC power supplies in automotive electronics, various telecommunications equipment, high speed computing and microprocessor based systems. It can also be used in switching applications and high-voltage and current-commutation circuits.

Working Principle

The 1N5804US rectifier is a Schottky-barrier type of diode. It is primarily a switching device and operates on the principle of minority carrier injection, where it allows only a small number of majority carriers to move through a junction or region by physics. This creates a space charge layer at the junction interface, which eliminates potential breaks and causes the diode to act as a rectifier or protector in a circuit. The minority carriers then conduct current through the device by creating a voltage drop across the junction barrier. This voltage drop is typically what is considered a rectifier.

The advantages of Schottky-barrier diodes include low switching losses and reverse-recovery time, low forward voltage drop, and no reverse currents under most conditions. The disadvantage is a relatively high reverse leakage current, and the Schottky-barrier diode may suffer from reliability problems due to junction degradation over time.

Conclusion

The 1N5804US diode is a type of single-phase, ultra-fast recovery, glass-passivated Schottky rectifier. It is suitable for a wide range of applications due to its medium voltage rating, low forward voltage drop, low switching losses and low reverse-recovery times. The main disadvantage is its relatively high reverse leakage current. The 1N5804US can be found in automotive electronics, telecommunications equipment, high speed computing and microprocessor based systems, and more.
