STMicroelectronics 200V 1.5A Switching Diode, DO-214AC Surface Mount Package STTH1R02A

The STMicroelectronics STTH1R02A is a high-speed switching diode designed to deliver consistent performance in a wide range of rectification and power conversion applications. With a peak reverse repetitive voltage of 200V and a continuous forward current capability of 1.5A, this diode is well-suited for use in switching power supplies, industrial converters, and other demanding electronic systems.

This diode's fast reverse recovery time of 30ns makes it ideal for applications where switching speed and efficiency are critical, such as in high-frequency inverters and snubber circuits. Its low maximum forward voltage drop of 1.2V helps minimize conduction losses, further improving energy efficiency in power designs.

Encapsulated in a compact DO-214AC (SMA) surface-mount package, the STTH1R02A supports streamlined, automated PCB assembly and efficient use of board space. The package's dimensions - approximately 4.6 mm in length, 2.95 mm in width, and 2.03 mm in height - allow for high-density mounting in modern electronic assemblies. The device is configured as a single rectifier with a 2-pin count and a single diode configuration, making circuit layout straightforward for designers.

The diode is engineered to function reliably across a broad ambient temperature range, with a minimum operating temperature of -65°C and a maximum of 175°C, making it suitable for both consumer and industrial environments. It provides strong transient resilience with a peak non-repetitive forward surge current of 60A and maintains a low maximum reverse leakage current of 3μA. The rectifier type is classified as switching, highlighting its suitability for dynamic circuit environments.

As a RoHS-compliant component, the STTH1R02A meets international environmental safety standards. It is widely deployed in industrial, automotive, and consumer electronics, powering everything from AC/DC adapters and SMPS circuits to battery chargers and microcontroller-based systems.

For engineers seeking a reliable, fast-switching, and space-efficient rectifier diode, the STMicroelectronics STTH1R02A provides an excellent balance of electrical performance and physical compactness with a wide temperature tolerance, making it an ideal choice for modern, high-reliability electronics projects.
