3EZ36D10E3/TR12 Application Field and Working Principle

The 3EZ36D10E3/TR12 is a high power-to-package ratio Zener diode designed for use in telecom applications. This diode features an industry-standard TO-252 (IPAK) package and a temperature range of -55°C to 175°C. The VZ voltage range is designed to provide a good bandgap reference accuracy over the temperature range and is available in two different packages.

The 3EZ36D10E3/TR12 device operates in the reverse breakdown mode, which is used to protect the device from over-voltage conditions. When the voltage across the diode increases, the diode enters the reverse breakdown region and starts to conduct. This "clamping" or "shunting" voltage, or Zener voltage, is specified on the SmartDiodeTM chip itself. In essence, the specified Zener voltage is the maximum voltage level of the device after the breakdown.

This diode can be used in applications such as cellular phones, laptop computers, telecom equipment, and networking equipment. It can also be used as a clamping device in power supplies, where it can protect sensitive components from over-voltage events. The 3EZ36D10E3/TR12 device is designed with a power dissipation rating of 6.6W and can handle up to 16W in pulsed conditions. This helps ensure the device can withstand high power surges without fail.

The 3EZ36D10E3/TR12 is designed to operate within the range of 4.5-28V. When operated in this range, the diode provides protection against over-voltage events such as ESD, over-voltage, and load dump. The device is also designed to provide excellent performance under harsh environmental conditions. The TO-252 (IPAK) package has a wide temperature range of -55°C to 175°C, which helps improve the reliability of the device.

The 3EZ36D10E3/TR12 also features a low leakage current of 0.1µA and a high surge capability of 24A, making it suitable for high-current applications. The device also provides excellent reverse leakage protection, with leakage currents as low as 100nA at 4.5V. The rated reverse power dissipation for the device is 0.4W.

In addition to its protection against voltage surges and over-voltage events, the 3EZ36D10E3/TR12 device can also be used as a temperature stabilizer. This is due to its wide operating temperature range and excellent thermal resistance. Thermal resistance is specified as 3.2°C/W in junction-to-case conditions. This helps ensure that the device maintains a constant temperature over a wide range of temperatures.

In summary, the 3EZ36D10E3/TR12 is an ideal choice for voltage protection and temperature stabilization in applications such as telecom, networking, laptop computers, and cellular phones. Its high power-to-package ratio, wide operating temperature range, and low leakage current provide excellent performance under harsh conditions. It is also designed with a high surge rating and excellent reverse current protection, making it suitable for high-current applications.
