The CMPZ5226B BK is a 3W single Zener diode with a maximum Zener impedance of 5.1Ω. This device has a wide range of applications and is commonly used for protection of electronic devices, such as telecommunications and computer equipment, against transient voltage and reverse polarity conditions. It is also popular in power supplies and in power line communications.

The CMPZ5226B BK operates on the principle of a reverse biased diode in which the minority carriers (electrons and holes) traverse the junction of two semiconductors, resulting in a flow of current in the opposite direction to the applied voltage. When the Zener voltage is applied, the diode will break down and the built-up minority carrier current flows through the junction into the diode. This causes a voltage drop across the junction.

The CMPZ5226B BK has a maximum Zener voltage rating of 5V, and a minimum Zener voltage rating of 4.1V. Its maximum peak Zener current is 100mA and its maximum Zener power dissipation is 3W. It has a thermal resistance of 500°C/W, with a junction ambient temperature range of -55 to +150°C and a storage temperature range of -65 to +150°C.

The CMPZ5226B BK has several advantages over other Zener devices, such as higher current ratings and improved device stability. Its low Zener impedance values result in a faster response to overvoltage conditions, minimising surge voltage. This device is designed for use in automatic insertion processes and its surface mount design reduces board space requirements.

In summary, the CMPZ5226B BK is a single Zener diode with a maximum Zener impedance of 5.1Ω. It is designed to provide protection against transient voltage and reverse polarity conditions in electronic device applications, such as telecommunications and computer equipment, as well as in power supplies and power line communications. It has a high current rating, low Zener impedance and fast response time, making it an ideal choice for such applications.
