BZX84B12-G3-08 is a single Zener diode from Diodes Incorporated, commonly used for general-purpose applications such as voltage regulation and EMI/RFI noise suppression. The device offers 12V of Zener voltage and a glass-passivated junction for reliability and long life expectancy. In addition, it has a high power dissipation rating of 500 mW and an operating temperature range of -55 to +215 degrees Celsius. The BZX84B12-G3-08 Zener diode has a reverse breakdown voltage of 10.8V to 11.2V, a peak forward surge current of 5A and a typical reverse current leakage of 3.3uA at 5V. In addition, it has a typical maximum current of 350mA, a maximum forward voltage drop of 1.1V and a voltage temperature coefficient of -0.08V/K. It is available in a SOT-23 package, making it suitable for space-constrained designs. Zener diodes are used in a variety of applications, beginning with basic voltage regulation which helps to maintain steady and consistent current flow. In general, Zener diodes act as a voltage source when forward biased, allowing current to flow freely, and vice versa when reverse biased, providing a voltage clamping effect. This is accomplished by the application of a small reverse bias voltage over the semiconductor junction, directing the current to the Zener than to any other parts of the circuit. In turn, this causes a voltage regulator and allows voltage levels to remain relatively constant or to be clamped at a specific value.Moreover, Zener diodes can be used to maintain a constant voltage even when subject to large variations in current draw, making them highly reliable voltage regulators. This is especially beneficial in switching power supplies, which can experience large amounts of current variation due to their operating frequency. By using a Zener diode to protect an inductor’s core saturation, the ripple of a DC power supply can be reduced.The use of Zener diodes in parallel can be found in inductive circuits, where again a constant voltage is needed to keep a certain level of current in the windings. The Zener diode’s parallel connection directs any voltage surges produced by the inductive circuit back into the source, thus providing protection from voltage spikes.In addition, the BZX84B12-G3-08 Zener diode can be used in microprocessor-based systems for EMI/RFI noise suppression. The device can be used to isolate digital signals from one another and to reduce the effects of common-mode noise on the system. This helps to minimize electromagnetic interference that could otherwise cause errors within the system, such as data corruption and cross-talk.Finally, Zener diodes are also commonly used in applications such as television sets, industrial controls, and test and measurement equipment. The proprieties of their reverse biasing let them locate their main current flow directions in the circuit and serve as current limiters in these cases. Overall, the BZX84B12-G3-08 Zener diode from Diodes Incorporated is extremely useful for a variety of general-purpose applications, offering reliable and consistent performance. The device features high power dissipation ratings and its voltage temperature coefficient helps maintain a stable current flow. Additionally, its small package size makes it ideal for space-constrained designs, while its reverse biasing capabilities are well suited for EMI/RFI noise suppression, voltage regulation and current limiting.
