STMicroelectronics Schottky Diode 650 V 20 A 2-Pin TO-220 Silicon Carbide STPSC20065D

The STMicroelectronics STPSC20065D is an advanced Silicon Carbide (SiC) Schottky power diode, specially engineered for high-performance applications that require fast switching, high efficiency, and robust voltage capabilities. Featuring a 650 V maximum reverse repetitive voltage rating and 20 A maximum continuous forward current, this diode is well-suited for demanding power supply and power factor correction (PFC) circuits, industrial converter topologies, and other high-speed switching environments.

Thanks to SiC technology, the STPSC20065D delivers virtually negligible reverse recovery time, allowing designers to minimize energy losses during switching and improve overall efficiency. Its Schottky structure ensures a stable forward voltage drop, rated at 1.65 V maximum, reducing conduction losses and heat generation during operation. The device supports a high peak non-repetitive forward surge current of 400 A, making it highly resilient to transient overloads that can occur in pulsed loads or power switching applications.

The robust TO-220 through-hole package integrates two pins and offers excellent thermal performance, simplifying PCB assembly and enabling efficient heat dissipation with standard heat sink solutions. Its compact form factor, with a length of 10.4 mm, width of 4.6 mm, and height of 15.75 mm, fits standard power electronic layouts. The diode is designed for easy implementation into board designs as a single device without the need for additional balancing or matching components.

Engineers benefit from the device's wide safe operating area, with a working temperature range from -40°C up to 175°C. Its low leakage current specification (2 mA maximum peak reverse current) ensures circuit reliability and energy savings during standby or low-power states. The single diode configuration makes it straightforward to incorporate into existing topologies, while its Schottky design supports quiet EMI performance.

Typical industrial uses for the STPSC20065D include switch-mode power supplies (SMPS), PFC boost circuits, high-speed rectification in AC/DC converters, and renewable energy systems where fast, efficient rectification is critical. Its automotive-standard rating supports deployment in transportation systems, while the robust build ensures reliable performance in industrial automation, instrumentation, motor drives, and control equipment.
