M1MA151WAT1G

Diode Arrays Overview

The M1MA151WAT1G is a dual common-anode switching diode manufactured by onsemi. It features two silicon junction diodes housed in a surface-mount SOT-323 (SC-70) package with three pins. The device supports a maximum reverse voltage of 80V and handles continuous forward currents up to 150mA per diode. It operates within a temperature range of -55°C to +150°C, with a maximum power dissipation of 385mW.

Diode Arrays Feature Summary

• Dual configuration with a shared common anode for efficient circuit layout
• High thermal stability supporting operation up to 150°C
• Compact surface-mount packaging suitable for space-constrained designs

Diode Arrays Applications

• General-purpose signal switching circuits
• Protection against reverse polarity or voltage spikes
• Clamping applications in low-power digital logic interfaces

Diode Arrays Procurement Notes

Verify the specific suffix WAT1G against official datasheets to confirm pinout orientation and tape-and-reel specifications. Ensure the selected component matches the required 80V reverse voltage rating for the target application environment. Cross-reference the SOT-323 footprint dimensions during PCB layout finalization.

Diode Arrays Selection Notes

Select this component when a compact dual-diode solution is required for signal steering or protection. The common-anode topology simplifies biasing compared to discrete single diodes. Evaluate the 150mA current limit against peak load requirements to ensure reliable long-term operation under thermal stress conditions.

Diode Arrays Part Context

This part belongs to onsemi's standard discrete diode portfolio, designed for general electronic equipment. It complements other SC-70 series components by providing integrated dual functionality. The product line focuses on reliability and miniaturization for consumer and industrial electronics.

Diode Arrays Replacement Considerations

Check for direct equivalents such as the M1MA142WAT1G if different internal configurations are acceptable. Verify that any substitute maintains the identical SOT-323 footprint and 80V reverse voltage rating to ensure mechanical and electrical compatibility.
