Diodes are widely used in electronics and are one of the most fundamental components of any circuit. One type of diode is the Rectifier diode, also sometimes referred to as a ‘unidirectional’ diode. The 10TQ045S is a common single Rectifier diode, and this article will look at the application field and working principle of this device.

Application Field

The 10TQ045S Rectifier single diode is mainly used in power supplies, including high frequency switching power supplies, switching adapters, high frequency rectification key components, bridge stock, lighting power supplies, and laptop computer power supplies. It can also be used in important aspects of industrial technology such as LED lighting, LED display, LED circulation lighting power supply, and audio equipment.

Different types of rectifier diodes have different application fields due to their differences in power and reverse current capabilities. The 10TQ045S Rectifier diode is most suitable for use in low-end low-power applications, such as those mentioned above. It is suitable for use in medium and high-power applications, such as photographic technology, laser technology and microwave electrical systems, however other more powerful rectifier diodes are more suited to these applications.

Working Principle

Rectifier diodes are internally made up of two layers of semiconductors - generally a p-type semiconductor and an n-type semiconductor. In the p-n junction, when electrical current passes through the external circuit, the current only passes through the diode in one direction, while passing in the opposite direction the current will not pass through, like a one-way gate.

The 10TQ045S is classified as a single Rectifier diode - in this type, when the voltage of the p-type semiconductor is higher than the n-type semiconductor, the current will flow from the p-type to the n-type and the diode will be in a ‘on‘ state. This is referred to as a forward bias. When the voltage of the n-type semiconductor is higher, the current will not be able to pass through and the diode will be in an off or ‘reverse bias’ state.

Conclusion

The 10TQ045S is a single Rectifier diode, primarily used in low-power applications in the fields of LED lighting, LED display and LED circulation lighting power supply. Its working principle is based on the theory that in the p-n junction, when the voltage of the p-type semiconductor is higher than the n-type semiconductor, the current will pass from the p-type to the n-type and the diode will be in a ‘on’ state. When the voltage of the n-type semiconductor is higher, the current will not pass through and the diode will be in an off or ‘reverse bias’ state.
