STMICROELECTRONICS STTH3012W Ultrafast Recovery Diode 1.2kV 30A TO-247

The STMICROELECTRONICS STTH3012W is an Ultrafast Recovery Diode engineered for demanding industrial power applications. Encased in a robust, flame-retardant UL94V-0 epoxy package, its high-quality design ensures low leakage current, consistently reproducible electrical characteristics, and intrinsic ruggedness for long-term reliability.

These attributes make it an ideal component for heavy-duty applications such as industrial power supplies and other mission-critical systems requiring efficient rectification and freewheeling functions. It is also well-suited for auxiliary roles in snubber, bootstrap, and demagnetisation circuits. A key competitive advantage is its improved performance in minimising leakage current, thereby providing a greater thermal runaway guard band and enhancing overall system safety.

The diode excels with very low conduction and switching losses, enabling efficient high-frequency operation and handling high pulsed currents. It offers a high reverse voltage capability and can operate at a high junction temperature, ensuring stability under strenuous conditions. Its design prioritises durability and consistent performance in environments where failure is not an option.
