SS13L MQG Application Field and Working Principle

SS13L MQG is a single rectifier diodes which is used in many application fields, such as the automotive industry, automotive electronics, computer and others. The advantages of this diode can be summarized as good performance, high surge capability and low leakage current.

Basic Principle of Diode

The basic principle of diode is to allow current to flow in one direction but not in the other. This is possible by introducing an electric field into a special material - the semiconductor. The semiconductor has two regions: Anode and Cathode. When a voltage is applied across the diode, the anode becomes positive and the cathode becomes negative. As a result, the electric field from the anode to the cathode can break down the junction of the semiconductor and form a channel, allowing current to flow.

Working Principle of SS13L MQG

The SS13L MQG is a single rectifier diode with ratings of 200mA/100V. It is composed of two PN junction (anode and cathode). In order to improve the current carrying capacity and reduce the forward voltage drop, an N-type layer is added between the anode and the cathode to form a double PN junction. The anode of the diode is connected to the positive voltage while the cathode is to the negative voltage. When the voltage across the diode exceeds the threshold voltage, the diode will turn on and allow current to flow from anode to cathode. When the applied voltage is removed, the diode will immediately turn off and prevent current flow. When the reverse bias voltage is applied, the diode works as an open circuit and no current flows from the anode to the cathode. The reverse breakdown voltage of the diode depends on the current.

Applications

The SS13L MQG single rectifier diode is typically used in automotive, automotive electronics, computers and other applications. Because it has good performance, high surge capability and low leakage current, it is a reliable component in modern electronic products. In automotive applications, it is typically used to switch or regulate the current flow in the electrical circuits. It can be used in entry/exit door switches, power window lifts, power locks, speed or engine control, lighting, audio and many other applications. In automotive electronics, the diode can be used to regulate the voltage output of electronic circuit to provide a stable supply voltage to electronic devices such as microcontrollers, sensors, and etc. The SS13L MQG also has uses for computers. It can be used as a rectifier in the power supply unit to convert AC signals to DC signals. It also can be used in flash memories to store information and in safety systems, such as a circuit breaker.

Conclusion

The SS13L MQG is a single rectifier diode which has ratings of 200mA/100V. Its working principle is based on the electric field across the two PN junction (anode and cathode). It has many application fields, such as automotive, automotive electronics, and computer. It has good performance, high surge capability and low leakage current, which makes it reliaible and suitable for modern electronic products.
