CMZ5939B BK

The CMZ5939B BK is a single zener diode. It is one of the most common diodes used in modern electronics and has a wide range of applications. The specific application of this diode is to provide voltage regulation and prevent reverse current in an electronic circuit. This diode can be used to help stabilize the voltage output in a switching power supply and to prevent voltage spikes resulting from sudden changes in load. It can also be used to protect sensitive electronic equipment from voltage transients and surges.

The CMZ5939B BK has a breakdown voltage of 5.9 V and a reverse power dissipation of 30 mW. It is manufactured in a plastic package with a total height of 2.3 mm, making it very suitable for surface mount applications. Its maximum operating temperature is 125°C and it is capable of handling up to 0.2 A in forward operating voltage. This diode can provide a reliable and stable voltage reference for a variety of applications.

The working principle behind the CMZ5939B BK zener diode is quite simple. When a voltage higher than the breakdown voltage is applied to the diode, a strong electric field is created within the junction. This field causes the electrons to become highly energetic, resulting in a current flow called zener breakdown. The current flow is proportional to the applied voltage, until the maximum reverse current rating or voltage is reached, at which point the diode will become reversebiased. This allows the diode to act as a voltage regulator, dropping any excessive voltage to the desired value.

The CMZ5939B BK zener diode is a very versatile component with a wide range of applications. It can be found in many consumer electronics, such as LCD TVs, computer monitors, and mobile phones. It is used to provide voltage regulation, provide reverse voltage protection, and act as a voltage reference. Its low profile and wide operating temperature range makes it ideal for surface mount designs.
