Diodes - Zener - Single

The CMHZ5262B TR is part of a family of standard Zener diodes that offer low leakage, low dynamic resistance and wide operating temperature range. These diodes have a precise Zener voltage which enables them to deliver both stable voltage regulation and reverse voltage protection. Depending on their application, these diodes offer precise voltage regulation within a wide -3% to +3% of its precise rating. These diodes can be used as both a shunt regulator and voltage reference in power supplies, circuit protection, and any application needing to protect against equipment damage due to excess voltage.

Application Field

The CMHZ5262B TR is typically used in the following fields:

• Computer Motherboards and Servers
• Communications Equipment
• Power Supplies
• Multimedia Applications
• Automotive Applications
• Portable Electronics

The main applications for these diodes include voltage regulation, buck-boost conversions and limiting, controlling, and shunt voltage functions. They are ideal for applications demanding precise voltage regulation and reverse voltage protection.

Working Principle

The basic operation of Zener diodes is similar to that of normal rectifier diodes; However, unlike normal diodes, Zener diodes allow reverse current flow when the voltage across its terminals reaches a certain breakdown voltage, known as the Zener voltage. Its breakdown voltage is due to the presence of an electrically active material in the diode\'s junction region that allows electrons to move from the n-type side to the p-type side. This additional current flow is known as Zener current as it flows in the reverse direction of the applied voltage. The Zener voltage of a Zener diode is determined by its physical design, in addition depending on temperature, the Zener voltage can vary too. The Zener voltage can vary from its expected value by a few percent, usually from -3% to +3%. To ensure its operational accuracy, these diodes typically specify a maximum tolerance in terms of percent deviation of the diode’s Zener voltage from its rated value. The CMHZ5262B TR belongs to the family of Zener diodes with a Zener voltage range of 3V to 6V. It has a maximum precision of -3% to +3%. The diode also has an operating temperature range of -55 degrees Celsius to +125 degrees Celsius. The diode also features an extremely low dynamic resistance resulting in limited power loss and an equally low reverse leakage current, leading to less wasted power.

Conclusion

The CMHZ5262B TR is a versatile and reliable Zener diode that offers great performance and accuracy in a wide variety of applications. It is ideal for use in power supplies, circuit protection and voltage regulation applications. With its ultra-low dynamic resistance and low reverse leakage current, this diode is highly recommended for those looking for reliable, precise, and efficient performance. The diode’s rigid and precise voltage regulation within -3% to + 3% of its specified rating makes it an excellent choice for those needing to protect their equipment from damage due to excessive voltage. This Zener diode is considered to be a great choice for both industrial and consumer applications due to its low power consumption and wide operating temperature range.
