STPS1545G Description

The STPS1545G from STMicroelectronics is a Schottky rectifier diode designed for high-efficiency power applications. With a 45V reverse voltage (Vr) and 15A average forward current (Io), it delivers robust performance in demanding circuits. Its fast recovery time (<500ns) and low forward voltage drop (840mV @ 30A) minimize power losses, making it ideal for switching power supplies and DC-DC converters. Packaged in a D2PAK (TO-263) surface-mount form factor, it combines high current handling with thermal efficiency. The diode is RoHS3 compliant and operates up to 175°C junction temperature, ensuring reliability in harsh environments.

STPS1545G Features

• Schottky Technology: Low forward voltage and fast switching reduce conduction and switching losses.
• High Current Capacity: 15A continuous current rating with surge tolerance for transient loads.
• Low Leakage: Only 200µA @ 45V reverse leakage enhances efficiency.
• Thermal Performance: 175°C max junction temperature and D2PAK package optimize heat dissipation.
• Compliance: RoHS3, REACH Unaffected, and ECCN EAR99 certified for global use.
• Obsolete Status: While discontinued, it remains a reliable choice for legacy designs or replacements.

STPS1545G Applications

• Switching Power Supplies: Efficient rectification in AC-DC and DC-DC converters.
• Motor Drives & Inverters: Fast recovery minimizes dead time in PWM circuits.
• Solar/Energy Systems: Low-loss operation in MPPT charge controllers.
• Automotive Electronics: Withstands high temps in LED drivers or battery management.
• Industrial Equipment: Robust performance in welding machines or UPS systems.

Conclusion of STPS1545G

The STPS1545G excels in high-current, fast-switching applications where efficiency and thermal management are critical. Its Schottky design and D2PAK packaging offer a balance of power handling and compactness, though its obsolete status may require alternative sourcing for new designs. Engineers valuing low Vf, minimal leakage, and high-temperature stability will find it a proven solution for power electronics.
