Replaces / Cross-Reference Part Numbers

• Serves as a direct replacement for diodes with the part number 15SQ045.
• Can be a suitable substitute for other axial Schottky diodes with equivalent 15A, 45V specifications. Always verify datasheets for critical parameters.

Compatibility & Fitment

• Engineered for use as a bypass diode in solar panel junction boxes.
• Suitable for applications including switched-mode power supplies (SMPS), reverse polarity protection, freewheeling diodes, and DC-DC converters.
• The Axial R-6 package is designed for through-hole PCB mounting or point-to-point wiring.

When to Replace

• Component fails testing with a multimeter (reads as a short or open circuit).
• Visible signs of overheating, such as discoloration or damage to the component body.
• Associated circuit exhibits a loss of power, reduced efficiency, or complete failure.
• Connected power source, such as a solar panel, shows a significant drop in output voltage under load.

Installation Tips

• Confirm correct polarity before soldering. The band on the diode body marks the cathode (-) side.
• Avoid excessive heat during soldering to prevent damage to the semiconductor junction. Use a heat sink on the leads for prolonged soldering.
• Ensure leads are not bent too close to the diode body to prevent mechanical stress on the hermetic seal.
• Verify the circuit's operating parameters do not exceed the diode's maximum ratings of 15A and 45V.
