IntroductionThe JANTX1N976D-1 is a single Zener diode that is used for various applications such as in switching power supplies, voltage regulators, and signal line protection. It is a 4.7V Zener diode with a maximum reverse voltage of 10 volts. The diode is housed in a low-profile TO-92 package with a low power version for operating under inrush and high power loads. The operating temperature range for this device is from -65°C to +125°C.Application Field and Working PrincipleThe JANTX1N976D-1 diode is ideal for a variety of applications including ESD protection, voltage regulation, and integrated circuits. In these applications, the diode works by regulating the voltage across a voltage source or load. The diode is designed to allow current to flow in one direction, with a reverse breakdown voltage that is adjustable. When the reverse voltage across the diode reaches its zener, also known as the break-down or collapse voltage, the diode conducts in reverse and the voltage across the diode is clamped to the zener voltage. This is useful in voltage regulation and ESD protection, as the breakdown voltage helps protect sensitive components from electrostatic discharge.The JANTX1N976D-1 can be used in circuit designs as both a diode and a voltage regulator. In circuit design, the diode can be used to provide over-current protection and to help regulate circuit voltages. For example, if a voltage rail dips slightly below the zener\'s breakdown voltage, the current through the diode is limited, thus protecting the circuit it is connected to.When the JANTX1N976D-1 is used as a voltage regulator, it helps maintain a stable voltage level at the output of the regulator. A Zener diode is ideal for low power applications, as it can be easily adjusted to match the voltage level. The diode is also ideal for temperature controlled applications, as it can handle temperatures of up to 125°C.ConclusionThe JANTX1N976D-1 is a single Zener diode used for various applications such as switching power supplies, voltage regulators, and signal line protection. This diode works by regulating the voltage across a voltage source or load, with a reverse breakdown voltage that is adjustable. The diode can be used in circuit designs as both a diode and a voltage regulator, along with providing over-current protection. The diode is also suitable for low power and temperature controlled applications, and is designed to handle temperatures of up to 125°C.
