Diode Arrays datasheet and documents for MA3D749

MA3D749

Diode Arrays Overview

The MA3D749 and MA3D749A are silicon epitaxial planar Schottky Barrier Diodes with a common cathode configuration. The MA3D749 supports a repetitive peak reverse voltage of 40 V, while the MA3D749A supports 45 V. Both variants handle an average forward current of 5 A and a non-repetitive peak forward surge current of 90 A. Key electrical parameters include a maximum forward voltage of 0.55 V at 2.5 A and a reverse current of 1.0 mA at rated voltage. They operate within a junction temperature range of -40 to +125 °C and feature a thermal resistance of 3.0 °C/W.

Diode Arrays Feature Summary

High dielectric breakdown voltage exceeding 5 kV for robust performance
Low forward voltage characteristics to minimize power loss
V-cut lead ends designed for easy mounting

Diode Arrays Applications

Switching mode power supplies

Diode Arrays Procurement Notes

Verify the specific part number suffix (MA3D749 vs MA3D749A) against the required reverse voltage rating before procurement. Confirm the package type is TO-220D-A1. Check the manufacturer's official website for the latest maintenance or discontinuation status, as specifications may change without notice.

Diode Arrays Selection Notes

Select the MA3D749 for circuits requiring a 40 V reverse voltage rating, or the MA3D749A for 45 V requirements. Ensure the design accommodates the 5 A average forward current limit and the 90 A surge capability. Verify that the operating environment stays within the specified -40 to +125 °C junction temperature range.
