Diodes - Zener - Single: 1PMT5930AE3/TR7 Application Field and Working Principle

A single Zener diode, such as the 1PMT5930AE3/TR7, is a specialized diode designed to allow current to flow in a single direction, while also performing a breakdown function at a specific reverse bias voltage. This section describes the 1PMT5930AE3/TR7 application field and working principle.

Application Field

The 1PMT5930AE3/TR7 is an axial-leaded semiconductor component containing a single Zener diode. It is composed of the low voltage Zener diode, 1PMT5930AE3, and a transistor, TR7, packaged in a 5mm diameter plastic SOD-123 package.

This diode is designed for enabling voltage-dropping applications, such as in power supply and voltage regulators. The 1PMT5930AE3/TR7 has an absolute maximum rating of 8.0 volts, allowing it to be used in a wide range of applications.

The 1PMT5930AE3/TR7 is also well suited for protection applications, such as protecting circuit components or data lines from overvoltage and electrostatic discharge (ESD) events. This diode can provide a high degree of protection for sensitive circuits and components.

In terms of circuit design and implementation, the 1PMT5930AE3/TR7 is a cost-effective solution for low-power applications where small currents are required and space is limited. The small size of the SOD-123 package makes it well suited for use in space-constrained designs.

Working Principle

The 1PMT5930AE3/TR7 operates according to the Zener diode working principle. This diode is designed to maintain a steady voltage across its terminals, even when a higher voltage is applied across them. This is due to a phenomenon called Zener breakdown, where a high electric field near the junction causes a current to flow in the opposite direction of the normal current flow.

The 1PMT5930AE3/TR7 has a reverse breakdown voltage of 7.65 volts and a zener impedance of 300 mOhms, allowing it to maintain a steady reverse voltage across its terminals, even when high levels of current are flowing. This makes it an ideal diode for voltage-dropping applications.

The transistor within the 1PMT5930AE3/TR7 can be utilized for switching applications. When a voltage difference is applied to its base, the transistor acts as a switch, allowing current to flow from its collector to its emitter. With the addition of the transistor, the 1PMT5930AE3/TR7 can also be used for switching applications, as well as for protection purposes.

Conclusion

The 1PMT5930AE3/TR7 is a single Zener diode with an integrated transistor that is ideal for voltage-dropping and protection applications. It has a low voltage rating of 8.0 volts and a reverse breakdown voltage of 7.65 volts, making it an ideal diode for low-voltage applications. Its reverse impedance of 300 mOhms allows it to maintain steady voltage levels even when high currents are flowing. The small size of the SOD-123 package also makes it ideal for use in space-constrained applications. The addition of the transistor allows the 1PMT5930AE3/TR7 to be used for switching applications as well.
