Frequently Asked Questions (FAQ)
Can the RB225T100 be safely used in new power supply designs despite being marked 'Not For New Desig
While the RB225T100 is labeled 'Not For New Designs,' it remains available in original stock and can be used in existing or legacy systems requiring a reliable 15A Schottky diode array. However, for long-term production, consider design updates with active-status alternatives to avoid future obsolescence risks. Use the RB225T100 only if your supply chain has secured sufficient inventory, or if redesign time is prohibitive.
What are the main thermal risks when operating the RB225T100 at 15A in a high-ambient temperature en
The RB225T100 has a maximum junction temperature of 150°C and a forward voltage drop of up to 860 mV at 15A, resulting in approximately 12.9W of power dissipation per diode pair. In high-ambient environments (>70°C), inadequate heatsinking can lead to thermal runaway. Always use a properly sized heatsink with low thermal resistance and verify performance under worst-case load and temperature conditions.
How does the RB225T100 compare to the STPS20S100CFP in terms of forward voltage and leakage current
The RB225T100 offers a maximum Vf of 860 mV at 15A, which is competitive with the STPS20S100CFP (~850 mV typical). However, the STPS20S100CFP has better leakage performance (typically <200 µA at 100 V) compared to the RB225T100's 400 µA max at 100 V. In high-temperature switching supplies, the lower leakage of the STPS20S100CFP may reduce standby losses, making it preferable if efficiency is critical.
Is the TO-220FN package of the RB225T100 suitable for automated through-hole assembly, and what are
Yes, the TO-220FN package of the RB225T100 supports automated insertion, but requires proper footprint design to ensure mechanical stability and thermal performance. Allocate sufficient copper area for the leads and exposed tab (if thermally connected), maintain creepage distances for 110V operation, and avoid via-in-pad under high-current traces to prevent solder wicking and joint weakness.
What are the reliability concerns when replacing a standard rectifier with the RB225T100 in a revers
When using the RB225T100 for reverse polarity protection, its Schottky characteristics offer low forward drop, reducing heat generation at high currents. However, its 400 µA reverse leakage at 100 V can be problematic in battery-powered systems, potentially causing discharge when off. Ensure system idle current budgets account for this leakage, and verify that the 110V Vr rating provides sufficient margin above the maximum input voltage to prevent breakdown.
