Introduction

The HSM825JE3/TR13 is a single rectifier diode in a TO-220 package. It is a Fast Recovery rectifier, meaning it recovers quickly after reverse-bias is applied across its leads. In other words, the HSM825JE3/TR13 is a fast-acting device that can handle relatively large currents when the necessary conditions are met.

Application Field

The HSM825JE3/TR13 fast recovery rectifier has many uses in the field of electrical engineering. Its features make it suitable for power supplies, DC-to-DC converters, and motor driver circuits.

The HSM825JE3/TR13’s fast recovery feature helps reduce the size of the electrolytic capacitors in switch-mode power supplies, allowing them to be housed in a smaller package. This reduces cost and increases efficiency.

The HSM825JE3/TR13 also finds use in motor driver circuits. Its fast recovery capability allows it to quickly reset and prevent the circuit from exceeding its current limit, thus preventing damage to the motor.

Finally, the HSM825JE3/TR13 is well-suited for DC-to-DC converter circuits. Its fast recovery feature helps speeds up the response time of the converter, allowing it to store more energy in fewer switching cycles. This helps reduce the size of the overall system.

Working Principle

The HSM825JE3/TR13 single rectifier diode functions on the principle of semiconductor rectification. When a voltage is applied across the leads, electrons are forced to flow in one direction through the diode, whereas no current will flow in the opposite direction. By controlling the voltage applied to the diode, the current flow can also be controlled.

The HSM825JE3/TR13’s fast recovery feature is due to its design. The diode is constructed with a special low-impedance “trench” structure that decreases “ringing”, which is the slow recovery of a diode. The low-impedance structure helps reduce the slow recovery period, allowing the diode to recover quickly after reverse-bias is applied.

Conclusion

In conclusion, the HSM825JE3/TR13 is a fast-acting rectifier diode that finds use in a range of applications, from DC-to-DC converters to motor driver circuits. Its design features a low-impedance “trench” structure that enables fast recovery. This makes it an efficient and effective choice for a variety of applications.
