3EZ140D10/TR8

Introduction

The 3EZ140D10/TR8 diode is a popular single Zener diode with many applications in the field of electronics. This type of diode is typically used in applications where a reverse voltage of 8 volts DC is needed to override the source voltage and provide controlled power. It is also used in DC-DC converters as a clamp, and in current-limiting circuits as a voltage regulator.

Application Field

The 3EZ140D10/TR8 diode is commonly used in a wide range of electronics and electric applications, including:

• Safety systems and devices such as circuit breakers and electric ovens – the diode helps protect against potential electric shocks and electrical surges.
• Electronic components and products that require a specific reverse voltage including DC-DC converters and voltage regulators.
• Analog and digital semiconductors, integrated circuits and computer systems – Zener diodes are used in some systems to provide overvoltage and ESD protection.
• Consumer electronics such as electric motors, generators, power supplies, automotive electronics and home electronics. The diode helps maintain consistent levels of power and increase battery life.

Working Principle

The 3EZ140D10/TR8 diode works on a self-regulating principle. When the applied current is below the rated current, the diode behaves as any other typical rectifier and permits the current to pass easily through it. This is called the forward-bias current. When the applied current tries to exceed this rated current, the diode limits the current flow and reduces it to the desire current by providing an opposing voltage.

The diode enters into a reverse bias state when the current exceeds the rated current and can no longer be passed through the diode. In this state, the diode acts as a Zener and provides an opposing voltage in order to limit the current flow. This is known as the Zener voltage.

When the current exceeds the Zener voltage, the diode acts as a shunt and stops the current flow to maintain a consistent voltage level.

Conclusion

The 3EZ140D10/TR8 diode is a single Zener diode with many applications in the field of electronics. This diode can be used in safety systems, DC-DC converters, current-limiting circuits, analog and digital semiconductors, consumer electronics and other electronic components. It works on the principle of self-regulation, and when the current exceeds the rated current, it enters into a reverse bias state which provides an opposing voltage in order to limit the current flow.
