2EZ120D2/TR12

Diodes - Zener - Single are a type of diode intended to have a specific voltage drop when operating in reverse voltage and suitable for regulating, clamping and steering circuits. The 2EZ120D2/TR12 is a single Zener diode manufactured by Netcom Corporation. This device is designed for applications requiring a regulated, low-impedance source for a wide range of frequencies up to 20 watts.

The 2EZ120D2/TR12 is a voltage-stabilizing diode designed to regulate the reverse voltage across a load when the applied voltage is greater than the Zener voltage. It is capable of operating in a wide range of temperatures, from -65 to +150 °C. It has a maximum power dissipation of 2 W and a large temperature coefficient range of -1 to +1.5%.

The 2EZ120D2/TR12 consists of two series-connected elements, a Zener diode and a resistor. In the forward direction, the Zener diode diverts the current to the resistor. When the forward voltage exceeds the Zener voltage, the Zener diode breaks down and circuits the resistor. At the same time, the resistor acts as a current limiter and limits the current flowing through the circuit. In the reverse direction, the diode limits the voltage across the load to the Zener voltage.

The function of the 2EZ120D2/TR12 is to provide a regulated source of voltage under reverse-biased conditions, making it ideal for use in voltage regulator circuits. Its low impedance characteristic makes it suitable for a wide range of power electronics applications, including switching power supply, battery charger, and other circuits where high frequency noise control is required.

In addition, the 2EZ120D2/TR12 can be used in power management systems to regulate the output voltage of the system and improve its energy efficiency. It is also useful for short-term peak transient voltage suppression. The Zener diode is particularly well suited for use in base station, portable radio and TV, and automotive electronics applications.

The 2EZ120D2/TR12 is a reliable, efficient and cost-effective solution for a wide range of applications. It is easy to install, requires minimal maintenance and offers excellent performance in terms of temperature stability, power dissipation and voltage regulation. It is an ideal choice for many applications demanding a regulated, low-impedance source for a wide range of frequencies up to 20 watts.
