STMicroelectronics Schottky Diode 40V 500mA SOD-123 Surface Mount Single Configuration STPS0540Z

STMicroelectronics STPS0540Z Schottky Diode 40V 500mA SOD-123 is engineered to deliver efficient current rectification and fast switching performance in power electronic circuits. Featuring a surface-mount SOD-123 package, this diode is ideally suited for compact layouts and automated PCB assembly. With a maximum continuous forward current of 500 mA and a peak reverse repetitive voltage of 40 V, it is optimized for low-voltage and medium-current applications such as switching power supplies, battery chargers, and signal rectification in industrial, automotive, and consumer electronics.

This Schottky diode utilizes single configuration with two pins and provides low forward voltage drop, rated at 0.5 V, which helps reduce power dissipation in the circuit. The rectifier type is Schottky, chosen for its fast recovery times and reliability in applications requiring rapid switching and minimal losses. The device is capable of withstanding a peak non-repetitive forward surge current of up to 5.5 A and has a peak reverse current as low as 40 μA, further supporting energy-efficient operation.

The SOD-123 package measures 2.85 mm in length, 1.7 mm in width, and 1.35 mm in height, making it a suitable choice for space-constrained circuit boards. The product operates reliably over a wide temperature range, from -65°C up to 150°C, and is designed to maintain stable performance in demanding environments. As the maximum operating temperature reaches 150°C, it provides excellent thermal resilience for automotive, industrial, and consumer projects.

STMicroelectronics is recognized for high quality and durability across its semiconductor portfolio. This Schottky barrier diode up to 1A is suited for high power, efficiency, and density requirements. It is recommended for applications in industrial automation, LED drivers, power conversion, battery management, and general-purpose rectification wherever fast and efficient switching is needed.

The STPS0540Z is not classified under automotive standards but can be used in automotive-grade circuits if those standards are not mandatory. Its single configuration and robust construction ensure ease of use and reliability for engineers and designers. No standards or approvals beyond typical RoHS compliance are specified for this product.
