Single rectifier diodes are the most common type of diode used for a variety of electrical and electronic applications. A single rectifier diode, such as the SS25LHMQG, is a type of semiconductor device that is made up of a pair of P-type and N-type materials and acts as a one-way valve for electric current flow, allowing current to flow in one direction only. The SS25LHMQG is a 1A, 100V rectifier diode in a TO-250 package, commonly used in switching, rectification, and overvoltage protection applications.

Applications

The SS25LHMQG is typically used in applications that require high power devices in low to medium power circuits, such as switching power supplies, hot-swapping and phase-shift applications. This diode is also applicable for rectification, over-voltage protection, voltage clamping and reverse polarity protection. The SS25LHMQG is designed to operate over a wide range of temperatures and can withstand up to 100V of reverse voltage.

Working Principle

A single rectifier diode, such as the SS25LHMQG, works on the principle of implanting an N-type and a P-type material in the same semiconductor material. When a voltage is applied across the diode, current will flow in one direction, typically from the P-type side to the N-type side. The reverse breakdown voltage is the voltage at which the reverse current occurs and can range from several volts to around 100V for the SS25LHMQG. The reverse breakdown voltage ensures that the device is protected from overvoltage conditions.

The forward current of a diode is dependent on the level of applied forward voltage. The SS25LHMQG has a maximum forward current rating of 1A and the forward voltage drop is typically around 0.7V, depending on the applied forward current. The SS25LHMQG also has a reverse current leakage rating of 20µA maximum.

Conclusion

The SS25LHMQG is a single rectifier diode with a maximum forward current of 1A and a reverse breakdown voltage rating of up to 100V. This device is suitable for applications that require high power devices in low to medium power circuits, such as switching power supplies, hot-swapping and phase-shift applications. The forward voltage drop is typically around 0.7V, while the reverse current leakage rating is 20µA maximum. This device is designed to operate over a wide range of temperatures and can withstand up to 100V of reverse voltage.
