Diodes are an important component of electronics and electric circuits. They can be used for rectification, voltage stabilization, signal mixing and other functions. Among them, Zener diodes are especially important types of diodes.

The 1N5347AE3/TR13 is a 3W axial leaded single Zener diode designed to meet the growing demands of the automotive and industrial markets.

Application Field

1N5347AE3/TR13 diodes are widely used in automotive applications such as voltage regulation and over-voltage protection. They are also used in industrial applications such as DC to DC converters, or general over-voltage protection circuits. It can also be used as a switching diode in circuits like voltage and current control, radio interference suppression and sensing circuits.

Working Principle

The 1N5347AE3/TR13 diode is a single Zener diode used for voltage regulation and over-voltage protection. When the reverse voltage is lower than the Zener voltage, a low impedance path is established from anode to cathode and serves as a reverse protection. When the reverse voltage is higher than the Zener voltage, the Zener diode will protect the circuit from over-voltage.

In its forward-biased state, the diode is in its linear region, meaning that the forward voltage across the diode is proportional to the forward current. It also has a breakdown voltage. When the reverse voltage exceeds the Zener breakdown voltage, it will conduct current in reverse bias and the reverse current will remain nearly constant regardless of the reverse voltage beyond the breakdown voltage.

The 1N5347AE3/TR13 diode operates within the temperature range of -55°C to +150°C, the revers voltage range of 6.8V to 200V, and the power dissipation up to 3W. Its non-repetitive peak pulse power can reach 8W.
