The HSM320J/TR13 is a single rectifier diode, popularly used in a variety of applications. It is usually found in the high power rectifying applications, mostly due to its high efficiency and extremely low reverse leakage current.

Application Field

The HSM320J/TR13 is a high power rectifier diode, so its primary application field is in high power applications. It can be used in various applications, such as switching mode power supplies, automatic battery chargers, AC-DC adapters, etc.

It is also suitable for high frequency switching applications as it features a very fast recovery time. Its low capacitance also makes it ideal for high frequency switching applications, as it minimizes losses due to capacitive voltage.

Furthermore, its low reverse voltage drop makes it suitable for the input bridge rectifier circuits of the DC to DC converters.

Working Principle

As a rectifier diode, the HSM320J/TR13 is designed to conduct current in one direction only. It does this by means of its p-n junction which blocks the current from flowing in the opposite direction.

When forward biased, the p-n junction of the HSM320J/TR13 is slightly less than 0.2V, thus allowing current to flow. In this state, the diode is said to be conducting and it acts as a short circuit.

When reverse biased, the p-n junction of the diode is made up of a depletion region which blocks the current from flowing. In this state, the diode is said to be blocking and it acts as an open circuit.

As a result, when current flows through the HSM320J/TR13, it will only flow in one direction, thus rectifying the current.

Conclusion

The HSM320J/TR13 is a single rectifier diode, suitable for high power applications. It is usually used in switching mode power supplies, automatic battery chargers, AC-DC adapters, high frequency switching applications and for the input bridge rectifier circuits of the DC to DC converters.

It works by means of its p-n junction which blocks the current from flowing in the opposite direction when reverse biased. When forward biased, the p-n junction allows current to flow, thus rectifying the current.
