Working principle of MMBZ5225C-HE3-08

MMBZ5225C-HE3-08 uses a Zener diode to regulate the voltage at its built-in Zener voltage level. Its working principle is that when the differential voltage between the two ends of the diode is greater than the Zener voltage, the anode current will flow freely. When the differential voltage is lower than the Zener voltage, the reverse current of the diode is blocked, and the differential voltage is kept at the Zener voltage.In addition, MMBZ5225C-HE3-08 also has the characteristics of reverse polarity protection. When the power supply voltage is reversed, there will be no current flow, and it will not cause any harm to the circuit. This feature makes MMBZ5225C-HE3-08 suitable for use in power MOSFETs and other circuits with reverse polarity protection requirements.
