STMicroelectronics 100 V 40 A Schottky Diode 3-Pin TO-220AB STPS40M100CT

STMicroelectronics STPS40M100CT is a high-performance Schottky barrier diode designed for industrial and commercial applications requiring efficient rectification with minimal losses. This diode is housed in an insulated TO-220AB package, which provides electrical isolation up to 2500 VRMS, making it safe for use in environments with demanding insulation requirements.

The STPS40M100CT supports a peak reverse repetitive voltage of 100 V and a continuous forward current rating of 40 A, ensuring robust operation in power supply circuits such as high frequency switch mode power supplies. Its low forward voltage drop of 780 mV combined with negligible switching losses improves overall efficiency and thermal management within circuits.

The device’s common cathode configuration and 3-pin layout facilitate straightforward integration into through-hole PCB designs. It can withstand peak non-repetitive forward surge currents up to 530 A, demonstrating durability under transient conditions.

Operating temperature ranges from -65°C to 150°C, allowing usage in a broad variety of industrial and automotive-adjacent environments, although it is not certified to automotive standards. Its compact dimensions (15.75 mm height, 10.4 mm length, 4.6 mm width) make it suitable for space-conscious power electronics assemblies.

Additional characteristics such as low leakage currents and a typical junction capacitance of 45 pF enhance switching performance and noise immunity. The insulated ISOTOP package type also ensures capacitance is minimized, supporting high-frequency applications.

This STMicroelectronics Schottky diode minimizes power losses due to its low forward voltage and negligible switching losses. The insulated TO-220AB package improves safety and electrical isolation in your power electronics projects.

Robust ratings of 40 A continuous current and 100 V reverse voltage enable reliability under harsh electrical loads. Compact size and through-hole mounting simplify physical integration onto PCB assemblies. Suited for industrial power supplies, automotive power management, and general electronics requiring high efficiency rectification.
