STMicroelectronics 45 V 30 A Schottky Diode, 3-Pin TO-263 Package STPS3045CG-TR

STMicroelectronics STPS3045CG-TR is a 45 V 30 A Schottky diode housed in a compact, surface-mount TO-263 (D2PAK) package with 3 pins. It is engineered for applications requiring efficient, fast switching and low conduction losses, such as switch mode power supplies, high-frequency DC to DC converters, and automotive electronic circuits.

The device features a dual center tap Schottky rectifier design that provides a 2x common cathode pair diode configuration, which enhances the diode's performance in polarity protection and free wheeling tasks. It excels in minimizing switching and conduction losses, supporting better energy efficiency in power conversion.

This diode supports a maximum continuous forward current of 30 A, a peak reverse repetitive voltage (Vrrm) of 45 V, and a peak non-repetitive forward surge current (Ifsm) of 220 A, making it robust for surge conditions. Its maximum forward voltage (Vf) is 840 mV, which reduces power dissipation during operation.

Operational temperature ranges from -65°C to 175°C, enabling usage in industrial and automotive environments. The device complies with standard electronic component requirements but does not have specific automotive certifications.

The diode measures 10.55 mm in length, 9.35 mm in width, and 4.35 mm in height, balancing compactness and effective thermal dissipation. Its 3-pin surface mount package facilitates easy integration on PCBs while maintaining reliable mechanical and electrical connections.

Very small conduction losses improve efficiency in switching power devices. Negligible switching losses enable high-frequency operation. Extremely fast switching diode enhances performance in DC to DC converters. Dual center tap design supports polarity protection and free wheeling applications.

Surface mount TO-263 package simplifies board design and thermal management. Wide operating temperature range of -65°C to 175°C for industrial use. Can handle peak surge currents up to 220 A for transient events. Low maximum forward voltage drop of 840 mV reduces heat generation.

Designed for automotive, industrial, and electronic power supplies. This product is ideal for engineers and technicians requiring reliable, high-performance Schottky diodes for power conversion, protection circuits, and automotive electronics.
