3EZ6.8D5/TR12

The 3EZ6.8D5/TR12 is a zener diode, which is a type of diode used for regulating and stabilizing voltages. The 3EZ6.8D5/TR12 is a single zener diode, meaning it has a single anode and single cathode connection instead of the two anode and two cathode connections that are more common in double zener diodes. This single zener diode enables applications with limited space while still providing the same performance and stability as double zener diodes.

The 3EZ6.8D5/TR12 has a voltage limit of 6.8 volts with a power rating of 1 watt. It is available in a DO-213 package, which is commonly referred to as a small outline diode (SMOD). The SMOD packages provide excellent protection and uniform impedance characteristics, making it well suited for use in applications with limited space.

The 3EZ6.8D5/TR12 is typically used in applications where the voltage needs to be limited or regulated, such as power supplies and DC-DC converters. In these applications, the voltage limit of 6.8 volts allows for current to flow in one direction only, ensuring that the voltage will remain stable and at the desired level. The 3EZ6.8D5/TR12 can also be used in applications where the voltage needs to be clamped to a specific level, such as over-voltage protection circuits.

The 3EZ6.8D5/TR12 operates on the same principle as other zener diodes, where the zener breakdown voltage is used to regulate the voltage by allowing current to flow in the reverse direction when the voltage exceeds the zener breakdown voltage. This is referred to as a “avalanche effect” and it is the same effect that is used in surge protection circuits, such as those found in home appliances and industry machinery.

The 3EZ6.8D5/TR12 offers excellent stability, is easy to use, and is well suited for a variety of applications due to its small form factor, low cost, and superior performance. This makes the 3EZ6.8D5/TR12 an ideal solution for voltage regulation and/or voltage clamping applications where space is a constraint.
