ES3D-M3/9AT, belonging to the category of Diodes - Rectifiers - Single, is a package of two diodes that are designed to protect various equipment against destruction due to overvoltage transients. This diode pair is designed to accept voltages of up to 9A and 800V peak, and to provide superior surge handling and lower capacitance than other types of available packages.

This Rectifier package provides very high-speed switching frequencies and is suitable for a wide range of applications: from low current to ultra-high current and from low voltage to ultra-high voltage levels. It can also be used in power supplies, DC-to-DC converters, AC-DC converters, motor control circuits, UPS systems, and more.

The diode package offers superior mounting options including plastic, ceramic, and metal versions. The plastic models are water-resistant and suitable for applications with high humidity. Ceramic and metal packages offer better mechanical performance, vibration resistance, and lower thermal impedance.

The nickel-plated leadframe contributes to excellent thermal performance, good circuit integration and design flexibility. The insulation layer isolates the two rectifiers and reduces the risk of short circuits. The two diodes are separated by a common connection, which ensures that they can be connected in series without connecting every component separately. Furthermore, this protects the circuit against transient overvoltages, while numerous safety features ensure that the device can be operated safely and reliably.

The working principle of ES3D-M3/9AT is quite simple. When the anode has a higher potential than the cathode, the diode conducts current through the N-type layer and the diode is said to have forward bias. This allows a current to flow from the anode to the cathode, but blocks any current from flowing from the cathode to the anode. The direction of current flow is from a higher potential to a lower potential. When the anode has a lower potential than the cathode, the diode does not conduct and is said to have reverse bias.

ES3D-M3/9AT is a versatile, high-performance rectifier partnership that can be used in a range of high-current and high-voltage applications. It is well-suited for power supply and signal switching designs where fast switching speed, reliability and superior surge handling are required. The device has excellent thermal properties and can be installed in plastic, ceramic and metal packages. The two diodes are separated by a common connection which provides high isolation and protection against transient overvoltages.
