In order to understand the application fields of JANTX1N4984CUS, and the working principle of this Zener diodes, further description is given below.

Application Fields for JANTX1N4984CUS

JANTX1N4984CUS are most commonly used in voltage-controlled oscillator (VCO) circuits, voltage stabilizers, power supplies, multiplexers, logic circuits, amplifiers and mixers. JANTX1N4984CUS are also used in video switching and signal processing circuits, such as the automatic gain control (AGC) circuit used in satellite signal reception. Furthermore, they are also implemented in low-current applications where the power consumption must be minimized, such as medical thermal imaging.

Working Principle of JANTX1N4984CUS

Based on the PN junction diode structure, the JANTX1N4984CUS has specific breakdown voltage characteristics. Below a certain voltage, the zener diode has a high resistance, so it behaves like an open circuit; this is known as the breakdown voltage, or the zener voltage. When the applied voltage exceeds this, the diode exhibits a lower resistance, and thus a smaller voltage drop, due to the avalanche breakdown effect. This zener breakdown characteristic is used to develop a stabilized voltage level in the application circuit.

JANTX1N4984CUS functions in the reverse breakdown region, so they are mounted with the anode connected to the most positive voltage and the cathode to the most negative voltage source. When the cathode voltage is a negative and greater than the reverse breakdown voltage, reverse current will flow through the diode, allowing it to regulate the output voltage. This can be used in various circuits such as voltage regulators, voltage stabilizers and voltage references.
