مقدمة المنتج:MM3Z9V1 مقدمة المنتج

The MM3Z9V1 is a 9.1 V nominal Zener voltage regulator diode in a SOD-323 surface-mount package, dissipating up to 200 mW on an FR-4 PCB. With +/-5% Zener voltage tolerance, 15 Ohm dynamic impedance at 5 mA, and Class 3 ESD rating (>16 kV HBM), it provides reliable voltage regulation and protection in low-power circuits. The device is second-sourced by onsemi, Diotec, and Secos with equivalent specifications. It is widely used in consumer and industrial electronics for bias, clamping, and reference applications.

مبدأ العمل:MM3Z9V1 مبدأ العمل

The MM3Z9V1 operates in the Zener breakdown region where the reverse-biased PN junction exhibits a controlled avalanche breakdown at 9.1 V. In this region, the current increases rapidly with voltage while the voltage remains nearly constant, providing voltage regulation. The Zener impedance of 15 Ohm at 5 mA test current represents the incremental slope (dV/dI) of the V-I characteristic at the operating point. The 200 mW power dissipation limit is determined by the thermal resistance of the SOD-323 package (approximately 500-600 deg C/W on FR-4). The device’s temperature coefficient is approximately +0.055%/deg C, meaning the Zener voltage increases with temperature for this voltage range.
