3EZ13D5/TR8

Diodes are components of electronic circuits which direct the flow of current in one direction and reduce the flow of current in the other direction. One of the most important types of diodes is the Zener diode, which regulates the flow of current by restricting the amount of voltage that can be applied to it. The 3EZ13D5/TR8 Zener Diode is a single-diode component specifically designed for voltage regulation and protection functions in low-power applications.

Voltage Regulation Features

The 3EZ13D5/TR8 has a choice of three terminal connections: Cathode (C), Anode (A) and Gate (G). When the Cathode and Anode connections are reverse-biased, i.e. the Cathode is connected to a higher potential than the Anode, the Zener diode operates as a voltage regulator. In this mode, the Zener diode limits the maximum voltage that can be applied to the Cathode by allowing a small leakage current to flow through it. The maximum amount of leakage current is determined by the reverse breakdown voltage of the diode, which is usually around 5 volts.

Protection Features

In addition to providing voltage regulation, the 3EZ13D5/TR8 can also be used to provide protection for other components in the circuit. This is achieved by the Gate connection, which is reverse-biased to the Cathode and Anode. When the reverse breakdown voltage of the Gate is exceeded, the Gate will conduct and cause the Zener diode to act as a short circuit, thus protecting other components in the circuit from damage due to excessive voltage.

Performance Characteristics

The 3EZ13D5/TR8 has an electrical performance characterised by a breakdown voltage of 5 volts and a maximum power dissipation of 0.25 Watts. The maximum operating temperature is 75ᵒC and the maximum junction and thermal resistance is 50ᵒC/W. The diode also has a capacitance of approximately 28 pF between the Cathode and Anode terminals.

Applications and Limitations

The 3EZ13D5/TR8 is mainly used for voltage regulation and protection of low-power applications and is suitable for use in a wide variety of electronic designs. As the maximum power dissipation is relatively low, the diode should not be used in applications where the power dissipation exceeds 0.25 Watts. In addition, care should be taken when operating the diode in circuits with high EMI and RFI as the diode may degrade in performance if exposed to large amounts of interference.

Conclusion

The 3EZ13D5/TR8 Zener Diode is a single-diode component specifically designed for voltage regulation and protection functions. Its features include a breakdown voltage of 5 volts and a maximum power dissipation of 0.25 Watts. The diode is suitable for use in a wide variety of electronic designs and is mainly used for low-power applications, however it should not be used in applications where the power dissipation exceeds 0.25 Watts. In addition, the diode may degrade in performance if exposed to large amounts of EMI and RFI, so care should be taken when operating in such conditions.
