STMicroelectronics Switching Diode 800V 1A DO-214AC Surface Mount STTH108A

The STMicroelectronics STTH108A is a high-voltage, fast-switching surface mount diode designed for demanding rectification and switching applications. This single rectifier diode employs a DO-214AC package, making it a preferred choice for dense PCB layouts across industrial, power, and electronics manufacturing environments.

Rated for a peak reverse repetitive voltage of 800V and a maximum continuous forward current of 1A, the STTH108A enables efficient power rectification in both AC and DC conversion stages. The fast reverse recovery time of just 75ns allows for quick switching, making it ideal for high-frequency circuits or rapid pulse operations where minimal energy loss and heat dissipation are critical.

The device is engineered for robust performance, supporting surge forward currents up to 20A, which enables safe operation during overload or transient conditions. Its minimum operating temperature of -50°C and maximum of 175°C extend usability into commercial and industrial applications demanding reliability in harsh conditions.

The DO-214AC (SMB) package provides a compact footprint, supporting automated assembly and ensuring mechanical stability on modern circuit boards. At a height of 2.03mm, length of 4.6mm, width of 2.95mm, and diameter of 2.71mm, this diode fits well into compact designs while facilitating the necessary thermal and electrical requirements.

STTH108A's configuration as a single switching diode makes it a versatile component for power supplies, inverters, motor drives, and other high-frequency electronic circuits. With a maximum forward voltage drop of 1.65V and a low peak reverse current of 5μA, it minimizes power loss and heat emission, supporting efficient energy conversion.

This diode is compliant with stringent standards for industrial and commercial use, including applications in manufacturing, power electronics, laboratory instrumentation, and embedded systems.
