Introduction to 1PGSMA4750HM2G

The 1PGSMA4750HM2G is a single Zener diode with glass body type. This diode belongs to the SMA package which has a total number of 2 pins. As a voltage regulator, it has a high power-switching capability and is great for applications that require low on-voltage losses. It is widely used in applications such as power supply systems, power conversion as well as automotive applications.

Potential Application Fields

The 1PGSMA4750HM2G is suitable for applications requiring over-voltage and over-current protection, as well as those requiring a stable voltage reference. The 1PGSMA4750HM2G can also be used for data transmission, microwave communication, and AC/DC power adjustment.

Working Principle

Basically, a Zener diode is used for regulating voltage. When the diode conducts, the forward-biasing voltage is shared by the diode and the other circuit components. The diode will then supply the exact voltage needed in the other components. The 1PGSMA4750HM2G keeps a steady current flow throughout.When the forward biasing voltage is removed, the diode will block further current flow. The 1PGSMA4750HM2G can then act as an over-voltage protector as it will absorb the excessive voltage. This keeps the other circuit components safe from being damaged due to high voltage.

Conclusion

The 1PGSMA4750HM2G is a single Zener diode with glass body type. This diode is suitable for applications that require low voltage losses, such as power supply systems, power conversion and automotive applications. Its main function is to protect other circuit components from over-voltage and over-current. The 1PGSMA4750HM2G operates by sharing the forward-biasing voltage between itself and the other components, which will then supply the exact voltage needed. Finally, when the voltage is removed, it will block further current flow, thus protecting other components from excessive voltage.
