1N4758E3/TR13

Diodes - Zener - Single

1N4758E3/TR13 is a type of diode, commonly known as a Zener diode. It is a component used to regulate the flow of electricity in circuits. Zener diodes have a special property – when reverse-biased, they begin to conduct electricity when the voltage magnitude reaches a certain value, known as the breakdown voltage. When the voltage exceeds the breakdown voltage, the Zener diode allows current to flow through in a reverse direction.

The 1N4758E3/TR13 is a single diode package with a breakdown voltage of 13V. It has a maximum power dissipation of 500 mW, with a maximum forward voltage drop (Vf) of 1.2 V. The operating temperature range is -65 to +175 °C. The 1N4758E3/TR13 is an ideal component for applications in the automotive, telecommunications, renewable energy, and LED lighting industries.

Application field

The Zener diode is a versatile component that plays a key role in many circuits. It is an ideal component for a wide range of applications, including:

• Switching: The Zener diode can be used as a switch or in switch-mode power converters.
• Clipping: The Zener diode can be used to limit voltage in the event of a sudden surge.
• Voltage regulation: The Zener diode can be used to maintain or adjust the voltage level in a circuit.
• RF Immunity: The Zener diode can be used to absorb and dissipate interference from high-frequency signals.
• Power conditioning: The Zener diode can be used to boost the current flow in the circuit.

The 1N4758E3/TR13 is one of the most popular types of Zener diodes, highly reliable and with a wide operating temperature. This makes it ideal for use in high-temperature environments, such as automotive and renewable energy applications.

Working Principle

1N4758E3/TR13 Zener diodes work on the principle of reverse conduction. When the anode is connected to a higher voltage than the cathode, the Zener diode creates a barrier between them, maintaining a constant voltage (Vz) on the anode side. When an excessive reverse voltage is applied to the diode, a breakdown occurs and the current (Iz) starts flowing through the diode in the reverse direction. This reverse current allows the diode to maintain the voltage to a constant level, even in the presence of transients in the circuit.

The characteristic of the Zener diode is determined by its maximum reverse breakdown voltage, which is the voltage at which the Zener diode starts to conduct. For the 1N4758E3/TR13, this value is 13V. The diode can also withstand a maximum of 500mW of power dissipation and a temperature of 175°C.

In addition to its reverse conduction, the Zener diode also has a low forward voltage drop. This is the voltage that is dropped across the diode when the anode is connected to a lower voltage than the cathode. The forward voltage drop of the 1N4758E3/TR13 is only 1.2V.
