1N2973A

The 1N2973A diode is a single Zener diode typically used as a voltage regulator in power supply systems. It provides an efficient way to regulate a supply voltage to a specific, predetermined voltage.

The 1N2973A diode has a variety of applications: It can be used to regulate the voltage from a generator or power supply in high power applications. It can be used to bypass excessive voltage peaks, which can be caused by the charging of capacitors. In low voltage applications, it can be used as a voltage supervisor to eliminate excessive current flow, offering a degree of protection from damage caused by overloads and transients. It also can be used to protect against thermal and Magnetic effects, prevent backflow of current, create logic levels and other operations.

The 1N2973A diode works by continuously comparing the voltage of the input source to the voltage at the cathode of the diode. If the input voltage is greater than the cathode voltage, the diode allows the current to flow through until the two voltages are equalized. If the input voltage is lower than the cathode voltage, the diode blocks the current and the cathode voltage remains unchanged.

The 1N2973A diode can handle up to 3 watts of power and has a breakdown voltage ranging from 5 volts to 39 volts. It is also available in a variety of different packages and voltage ranges. The 1N2973A diode is offered in an axial lead version which means the leads of the diode protrude from each side of the body using an external insulation sleeve for protection. The temperature range for the 1N2973A diode is -65°C to +175°C.

In conclusion, the 1N2973A diode is a single Zener diode typically used as a voltage regulator in power supply systems, and has a variety of applications. It is able to handle up to 3 watts of power, has a breakdown voltage ranging from 5 volts to 39 volts and is available in various packages. The 1N2973A diode uses continuous comparison of the input voltage to the cathode voltage to regulate the voltage supply.
