مقدمة المنتج:BZX284-C15 مقدمة المنتج

The BZX284-C15 from Nexperia is a 15V low-power Zener voltage regulator diode in the SOD110 very small ceramic SMD package. With a +/-5% tolerance (C suffix), 400 mW power dissipation, and 15 Ohm maximum Zener impedance at 5 mA test current, this diode provides stable voltage regulation for general-purpose applications. The SOD110 ceramic package offers excellent moisture resistance and reliability. The device features ultra-low reverse leakage current of 50 nA and a typical temperature coefficient of 11.4 mV/degC, making it suitable for precision voltage reference and protection circuits.

مبدأ العمل:BZX284-C15 مبدأ العمل

The BZX284-C15 operates in the reverse breakdown (Zener/avalanche) region when biased above its 15V Zener voltage. In this region, the diode maintains a relatively constant voltage across its terminals despite variations in current, provided the current remains within the specified range (5 mA test current). The Zener impedance of 15 Ohms represents the small-signal slope of the V-I characteristic at the operating point. The +/-5% tolerance ensures the actual breakdown voltage falls between 14.25V and 15.75V. The positive temperature coefficient of 11.4 mV/degC causes the Zener voltage to increase slightly with temperature, which is typical for Zener diodes above approximately 5V where avalanche breakdown dominates.
