Applications

• DC-DC converter circuits
• Power supply rectification stages
• Freewheeling diodes in switching regulators

Procurement Notes

Verify the specific suffix (e.g., TR) when ordering, as it indicates tape-and-reel packaging which differs from bulk or tray formats. Confirm RoHS compliance status directly with the manufacturer, as historical data may vary by production batch. Ensure the selected variant matches the required lead time constraints, as military-grade or specialized variants often have extended manufacturing cycles compared to standard commercial components.

Selection Notes

Select this component when a dual-diode arrangement is required in a minimal footprint. The 100 V rating suits low-voltage DC systems, while the 15 A current capacity handles moderate loads. Verify that the SMD-3 package aligns with the PCB layout constraints. Consider the 150°C junction temperature limit for high-temperature operational environments where standard silicon devices might fail.

Part Context

This part belongs to Microchip's discrete semiconductor portfolio, specifically within the Schottky diode category. It utilizes silicon technology to provide fast switching capabilities and low conduction losses. The product line is engineered for reliability in industrial and commercial power management applications, offering a robust alternative to standard PN-junction rectifiers in low-voltage, high-current scenarios.

Replacement Considerations

Cross-reference with other dual Schottky diodes in SMD-3 packages from Microchip or competitors. Ensure substitute parts match the 100 V reverse voltage and 15 A forward current ratings. Verify pinout compatibility and thermal resistance specifications to maintain system performance without redesigning the heat dissipation strategy.
