M1MA142WKT1G

Diode Arrays Overview

The M1MA142WKT1G is a common-cathade silicon epitaxial planar dual diode manufactured by onsemi. It is housed in an SC-70 (SOT-323) surface-mount package designed for low-power applications. The device features a maximum reverse voltage of 80 V and a forward current rating of 100 mA per diode, with a peak forward current of 150 mA. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA at 75 V, a forward voltage of 1.2 V max at 100 mA, and a junction capacitance of less than 2.0 pF. The component exhibits a fast reverse recovery time of under 3.0 ns, making it suitable for high-speed switching circuits.

Diode Arrays Feature Summary

• High-speed switching capability enabled by ultra-fast reverse recovery time and low junction capacitance.
• Common-cathode configuration allows for efficient circuit design in dual-diode applications.
• Automotive-grade reliability certified to AEC-Q101 standards with PPAP capability.
• Environmentally compliant construction featuring lead-free and halogen-free materials.

Diode Arrays Applications

• Ultra-high speed switching circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• Low-power surface mount designs

Diode Arrays Procurement Notes

Verify the specific suffix 'KT1G' against official datasheets to confirm packaging and tape-and-reel specifications. Ensure the part number matches the 80V reverse voltage variant, as other variants in the series may have different ratings. Confirm RoHS and halogen-free status requirements align with project specifications before procurement.

Diode Arrays Selection Notes

Select this component when designing circuits that require fast switching speeds and minimal parasitic capacitance in a compact footprint. The 80V reverse voltage rating suits applications with moderate voltage swings. Consider the common-cathode topology for shared ground reference designs. Verify thermal management needs, as the SC-70 package has limited heat dissipation capabilities compared to larger packages.

Diode Arrays Part Context

This device belongs to onsemi's family of silicon epitaxial planar dual diodes. It shares the same physical SC-70 package and general high-speed characteristics with models like the M1MA141WKT1G and SM1MA142WKT1G. The primary distinction lies in the reverse voltage rating, with this model specified for 80V operation, whereas others may be rated for 40V or differ in specific electrical limits.

Diode Arrays Replacement Considerations

Direct substitutes within the same family include the M1MA141WKT1G and SM1MA142WKT1G. Note that the M1MA141WKT1G has a lower 40V reverse voltage rating, which must be verified against circuit requirements. Ensure any replacement maintains the SC-70 package and common-cathode configuration for pin compatibility.
