How to Choose MOS Diodes

MOS Diodes Whether it is the decision to adopt N-channel or P-channel MOS transistors. In exemplary power usage, when the MOS transistor is grounded and the load is connected to the branch voltage, the MOS transistor constitutes the high-voltage side switch. In the high-voltage side switch, N-channel MOS transistors should be adopted due to consideration of the required voltage for open or conductive components. When the MOS transistor is connected to the bus and the load is grounded, a low-voltage side switch is used. Usually, P-channel MOS transistors are adopted in a certain topology, which is also out of consideration for voltage driving.

MOS Diodes Determine the additional voltage required, or the voltage that the machine can accept. The higher the additional voltage, the higher the profit of the machine. According to theoretical experience, the additional voltage should be greater than the branch voltage or bus voltage. That ability requires remaining cover, so that the MOS Diodes MOS transistor will not take effect. In terms of choosing MOS transistors, it is necessary to determine the acceptable voltage between the drain and source, i.e. VDS. It is important to know that the voltage that MOS transistors can accept will vary with the measurement. We need to test the range of voltage changes within the entire task measurement range. The additional voltage must have residual margin to cover a certain transition range, ensuring that the path does not take effect. The other insurance elements that need to be considered include voltage transients induced by electronic devices such as generators or transformers. There is no difference in the additional voltage used together; Generally, portable facilities are 20V, FPGA power supply is 20-30V, and 85-220VAC usage is 450-600V.
