How to Choose a Good MOS Tube
The first step is to decide whether to adopt N-channel or P-channel MOSFETs. In exemplary power usage, when a MOS transistor is grounded and the load is connected to the branch voltage, the MOS transistor is formed
It has become a high-voltage side switch. In the high-voltage side switch, N-channel MOS transistors should be adopted, which is due to the consideration of the required voltage for open or conductive components. When the MOS transistor is connected to the bus and the load is grounded, the low-voltage side switch needs to be used
Off. Usually, P-channel MOS transistors are adopted in a certain topology, which is also due to the consideration of voltage driving.
Determine the additional voltage required, or the maximum voltage that the machine can accept. The higher the additional voltage, the more
The higher the profit, the higher the profit. 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 transistor will not take effect. In terms of choosing MOS transistors, it is necessary to confirm the drain to source
The maximum voltage that can be accepted between poles, i.e. the maximum VDS. It is important to know that the maximum 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. Extra
The 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. No additional items used together
The voltage is also different; Generally, portable facilities are 20V, FPGA power supply is 20-30V, and 85-220VAC usage is 450-600V. The MOS transistor envisioned by Oko Semi Superconductor has strong withstand voltage power and a wide range of applications, making it highly popular among vast depositors.
