1SS367,H3F is a single-phase rectifier diode which belongs to the family of fast-recovery rectifiers. It is a general-purpose diode, meant for use in a variety of applications on switching-mode power supplies and power converters, in high frequency dc-dc converters, in line-powered telephone applications and in any other application requiring quick recovery. This diode can also be used in high power rectification in switching power converters, such as CFL appliances. Knowing its application field and working principle will help us understand its use in different circumstances.

Applications

1SS367,H3F is a single-phase rectifier diode used in a variety of applications, including switching-mode power supplies, line-powered telephone applications, CFL appliances, and more. It provides fast rectification and low forward voltage drop in these applications, improving the switching speed and output current performance.

Working Principle

When an AC voltage is applied to a rectifier diode, the positively charged half-cycle of the current passes through the diode and is rectified, resulting in a unidirectional current. The 1SS367,H3F diode is specifically designed with this in mind, and has a fast recovery time of approximately 30 ns. The fast recovery time allows the diode to quickly turn on and off, allowing it to process multiple cycles of power quickly. The fast recovery time also decreases power losses, as the voltage drop across the diode is kept to a minimum during its on and off cycles.

1SS367,H3F diodes are also designed for low forward voltage drop, keeping power losses to a minimum during rectification. The diode also has a high peak repetitive reverse voltage of 100 V, meaning that the diode can handle a large reverse voltage spike from an alternating current the diode is rectifying. It has a rated average forward current of 5 Amp, meaning that it can deliver this amount of current continuously.

Conclusion

In short, 1SS367,H3F is a single-phase rectifier diode that is designed to deliver fast rectification and low forward voltage drop. Its fast recovery time of 30 ns allows it to quickly process multiple cycles of power, while its low forward voltage drop keeps power losses to a minimum. It has a rated average forward current of 5 Amp, and a high peak repetitive reverse voltage of 100 V, making it suitable for a variety of applications. Finally, its fast switching speed provides excellent current performance for switching-mode power supplies and power converters.
