It is a low-cost device and is widely used in applications requiring general purpose pin protection, EMI suppression, and voltage regulation. It is used in various types of circuits, such as power supplies, adjustable voltage regulators, and DC-DC converters. The EDZVT2R27B is manufactured by a number of integrated circuit (IC) manufacturers.

Physical and Electrical Characteristics

The EDZVT2R27B is available in a variety of packages, and can be used in applications that require a wide range of power and performance characteristics. Its junction temperature range is -65 C to +150 C. Its forward voltage is 1.3V maximum and its power derating is 2.2W/Kelvin. It has a maximum power dissipation of 2W, a reverse voltage of 27V, and a forward current of 1.0A.

Applications

The EDZVT2R27B is typically used in applications that require voltage regulation, such as DC-DC converters, power supplies, and adjustable voltage regulators. It is also used in a wide range of EMI suppression, switching, and protection circuits. Additionally, it can be used in circuits that require the protection of low-voltage pins from over-voltage transients.

Working Principle

The EDZVT2R27B is a Zener single diode with a regular rectifier behavior. It works as a voltage regulator that provides a constant output voltage with variations in load or line voltage. When the input voltage is greater than the Zener breakdown voltage, a small current flows in the diode and the voltage across it remains constant. This voltage is lower than the input voltage and is equal to the Zener breakdown voltage (27V). When the input voltage falls below the Zener breakdown voltage, the diode stops regulating and the voltage across the diode equals the input voltage.

Conclusion

The EDZVT2R27B is a low-cost, widely-used, general-purpose Zener single diode that can be used in a variety of applications that require voltage regulation, EMI suppression, or protection of low-voltage pins. It features a maximum forward voltage of 1.3V, a maximum power dissipation of 2W, and a maximum reverse voltage of 27V.
