1N4625-1 is a single zener diode that operates in a wide range of applications. It is classified as a power-only zener, meaning that it has a relatively low forward voltage drop and is ideal for applications where high voltage spikes and static protection is needed. It is also suitable for temperature regulation applications because of its low temperature coefficient and low oscillation frequency.

The 1N4625-1 is based on the PN junction diode construction and works by utilizing the properties of a reverse bias voltage that is applied to the device. When the reverse bias is beyond a certain breakdown voltage, or zener voltage, it creates an electric field that is higher than the band gap potential barrier. As a result, the reverse current increases exponentially.

The 1N4625-1 is mostly used in rectifier, protection and Zener regulator circuits. In rectifier circuits, it is used to rectify AC to a positive DC input for further processing. In protection circuits, it is widely used to protect other components from overvoltage and short-circuit, as well as to stabilize voltages. It is also used in DC power supply circuits for overvoltage and short-circuit protection.

In Zener regulator circuits, the 1N4625-1 is used to regulate and maintain a constant voltage in the output. It works by utilizing the break down voltage where, when the input voltage is the same or higher than the zener voltage, the zener diode will conduct current and limit the output voltage to a certain regulated value, resulting in a stable output voltage.

The 1N4625-1 has many advantages; it has a low forward voltage drop allowing it to operate in power-only applications, it has a low temperature coefficient to ensure accurate and stable voltage regulation over a wide range of temperatures. The operating temperature range is also wide and it has a low oscillation frequency, making it suitable for both AC and DC power supplies.

In conclusion, the 1N4625-1 is a single zener diode that is used for a wide range of applications, from rectification, to protection and Zener regulation. It is based on the PN junction diode construction and operates on the principles of the reverse bias voltage and the break down voltage. It has a low forward voltage drop, a low temperature coefficient, a wide operating temperature range, and a low oscillation frequency, making it highly suitable for AC and DC power supplies.
