US2M

Single Diodes Overview

The MDD US2M is a surface-mount high-efficiency rectifier in the SMA (DO-214AC) package. It features a maximum repetitive peak reverse voltage of 1000V and an average forward rectified current of 2.0A at 55°C. The device supports a peak forward surge current of 50A and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.70V at 2.0A, a reverse recovery time of 75ns, and a DC reverse current of 5µA at 25°C. Thermal resistance is rated at 20°C/W.

Single Diodes Procurement Notes

Verify that the component matches the original MDD US2M specification sheet. Confirm the package type is SMA/DO-214AC with polarity marking on the case. Ensure compliance with RoHS standards and check for Underwriters Laboratory Flammability Classification 94V-0 certification. Validate terminal solderability per MIL-STD-750 Method 2026 before integration.

Single Diodes Selection Notes

Select this component for designs requiring 1000V reverse blocking and 2.0A continuous current in a compact SMD footprint. Consider the 75ns reverse recovery time for high-frequency switching requirements. Evaluate thermal management based on the 20°C/W junction-to-ambient resistance. Ensure the application load remains resistive or inductive, as capacitive loads require a 20% current derating.
