Introduction

V35PWM15HM3/I diodes, also known as single rectifiers, are widely used in various applications as devices for converting electrical energy from alternating current (AC) to direct current (DC). They are the simplest way to convert AC power to DC without a transformer. Generally, rectifier circuits are composed of one or more diodes connected in either full-wave or half-wave bridges, depending on the application. Rectifier circuits are found in almost every type of electronic device, especially those involving power, such as power supplies and electric motors. In this article, we will discuss the application field and working principle of the V35PWM15HM3/I rectifier diode.

Application Field

The V35PWM15HM3/I rectifier is a single package, high power, high-speed rectifier. Its main application is in industrial rectification both for AC to DC and DC to AC conversions. It is commonly used in power supplies, portable and rack-mounted power systems, and as a part of automotive power rectification circuits. The diode is also used in systems that require high power conversion with or without heat sinking. This type of rectifier is also used in AC welding machines, electric appliances, and various computer applications.

The V35PWM15HM3/I rectifier has excellent temperature stability, good shock resistance, and fast turn-on speed. Its high power rating and fast turn-on speed make it highly suitable for power applications that require fast switching, such as auxiliary rectifiers, protected power circuits, switching regulators, and dynamic braking. This diode is also capable of high-frequency applications, such as in switching supplies, inverters, and flyback converters.

Working Principle

A single rectifier diode consists of a N-type and P-type semiconductor junction. When a voltage is applied across the junction, the current flows from the N-type layer to the P-type layer. This is known as forward bias. When the applied voltage is reversed, the diode does not conduct, and this is known as reverse bias. The amount of current that the diode can conduct depends on the size of the junction and the applied voltage.

The V35PWM15HM3/I diode is a power rectifier. It can handle a maximum current of 15 A and a maximum reverse voltage of 750 V. In the forward-biased state, the diode has a voltage drop of 0.575 V. This voltage is referred to as the "forward voltage". This diode can also operate at high frequency, making it suitable for switching applications.

The V35PWM15HM3/I rectifier is also capable of blocking high voltages. This is due to its high reverse breakdown voltage rating. When the voltage across the junction is higher than the breakdown voltage, a leakage current will start to flow in the reverse direction. This is referred to as reverse breakdown. It is important to note that the junction temperature should not exceed the specified limit of the diode, otherwise it could result in permanent damage.

Conclusion

The V35PWM15HM3/I is a single rectifier diode with a high power rating and fast turn-on speed, making it suitable for a variety of applications. It is most commonly used in industrial rectification, both for AC to DC and DC to AC conversions. Its excellent temperature stability and good shock resistance make it suitable for high power and high frequency applications. In addition, it is capable of blocking high voltages due to its high reverse breakdown voltage rating.
