Diodes are commonly used for rectifying AC to DC since the current flow can be prevented rectified diodes became one-way street. SL04-HM3-08 is a single rectifier diode which is usually applied in various scenes. This article will focus on its application and working principle.

SL04-HM3-08 is a single-phase, general-purpose rectifier with ultrafast recovery rate. It has many specifications like forward voltage drop of 1.2V when the current is 5A, Reverse current IR of 5 µA and storage temperature range between -55°C and 150°C. It is made from diffused junction silicon which allows it to be suitable for high frequency and high power applications as it has low switching loss and low EMI. And due its special performance, SL04-HM3-08 can be widely used in industry, electronic and power electronic fields.

One of the typical application of SL04-HM3-08 is the bridge rectifier consisting four diodes to convert AC to DC. It is mainly used for producing full wave rectification, smooting and filtering which are usually found in power supplies circuits. And SL04-HM3-08 is also used in welding machine rectifier as it can provide high power and efficiency. Meanwhile, it can be also used in many electronic device like power switches and portable game console due to its excellent electrical features such as low forward voltage drop and ultrafast recovery.

The working principle of SL04-HM3-08 can be explained by its current flow. When the diode is in the forward bias condition, the current flows fom the anode to the cathode due to the electric potential. In this state, the diode will be conducting as the short-circuit resistance of SL04-HM3-08 is very low. When the diode is in the reverse bias condition, however, the current will blockerss as SL04-HM3-08 has a high resistance. This is the basic mechanic of rectifier diodes.

In conclusion, SL04-HM3-08 is a single rectifier diode with excellent electrical performance and great application scenarios. It can be widely used in welding machine and electronic device due to its fast recovery rate and low EMI.Its works under the basic principle of allowing current to flow when in forward bias and blocking it in reverse bias condition. This product is a ideal choice of many households and industrial application which need good quality, low forward voltage drops and low cost.
