3EZ120D2/TR8

The 3EZ120D2/TR8 is a single Zener Diode with a maximum average power dissipation of 500mW, operating at a maximum forward voltage of 1V. The device is available in a DO-35 (SOD-123TR) package and has a Zener voltage range of 6.2V to 7V, allowing for a wide range of voltage levels to be regulated. The device is able to operate at temperatures between -55°C and 150°C.

The 3EZ120D2/TR8 has two major applications: reverse voltage protection and adjustable voltage regulation. The diode is most suitable for use in applications requiring devices with low leakage current under reverse voltage and high reliability due to its soft recovery characteristic. As a voltage regulator, the diode is capable of providing stable output voltage levels with no additional circuitry, saving time and cost in the design of circuit boards.

The operating principle of the 3EZ120D2/TR8 is simple. When a current passes through the device, an electrical field is created which causes the p-n junction to become forward biased. This allows the passage of current, usually at a constant voltage due to its Zener voltage breakdown. When the current exceeds the Zener diode\'s max rated power dissipation, the device will cease to conduct and will not pass through any additional current.

The 3EZ120D2/TR8 is a robust and reliable single Zener diode, suitable for many applications. The device is able to offer extended temperature operating range and low leakage current characteristics, along with adjustable and stable output voltage levels. As such, it makes an ideal choice for many circuit boards, and its popularity among engineers is unsurprising.
