1N988B

Diodes are semiconductor components that have the capability to transfer power in one direction only. Zener diodes are diodes that are specialized to operate under reverse-biased conditions and provide constant voltage regulation.

The 1N988B diode is an example of a Zener diode. It is a Hermetically sealed, low-noise, precision, low-leakage, voltage-regulated diode, with a surface-mount package. It is designed for hydraulic power supplies, AC/DC converters, rectifier circuits, radio-frequency applications, and instrumentation circuits.

Application Field

The 1N988B diode is used for various electronic system applications requiring the low-leakage characteristics and smooth, consistent, and tight voltage regulation provided by Zener diodes. It can be a substitute for a Zener diode that results in a reduction in power usage or improved handling of larger current in a given area.

It is used in a wide range of applications, from precision analog circuitry to heavy duty power electronics. Its special characteristics make it suitable for use in audio and video equipment, telecommunications systems, computers, AC/DC power supplies, servo drives and motor control, and digital control processes.

The 1N988B diode is also used extensively in automotive systems, including laser-guided navigation, tire pressure monitoring systems, lane departure warning systems, and vehicle immobilizers.

Working Principle

The primary purpose of a zener diode is to regulate the voltage level across it. Unlike normal diodes, zener diodes are designed to work in reverse bias condition. When the zener diode is connected in reverse bias, the depletion region in the diode acts like a barrier of electrons. This barrier prevents the current to flow across it.

When a reverse voltage is applied across the diode, a certain voltage level is reached at which the depletion region breaks down. This breakdown voltage is known as the zener voltage. The breakdown voltage of the 1N988B diode is 4.7V +/- 0.1V.

The Zener voltage helps maintain the voltage across the diode. The current through the diode is also limited. This helps protect other components in the circuit from higher than normal voltages. With the 1N988B diode, the current is limited to a maximum of 200mA

Conclusion

The 1N988B zener diode is a Hermetically sealed diode designed for use in voltage-regulated circuits. It is suitable for use in a wide range of applications, including precision analog circuitry and power electronics. It is a low-noise, low-leakage diode with a maximum current rating of 200mA. The 1N988B diode works by maintaining a constant voltage level across it when connected in reverse bias and limiting the current through it.
