STTH2003CT/CG/CF/CR/CFP is ST's dual center tap fast recovery epitaxial diodes suitable for switch mode power supply and high frequency DC/DC converters. This device is packaged in TO-220AB, ISOWATT220AB, TO-220FPAB, I2PAK or D2PAK, and is especially intended for secondary rectification.
The STTH2003 series are dual‑center‑tap fast‑recovery epitaxial diodes designed for high‑frequency switch‑mode power supplies and DC‑DC converters. They are offered in several insulated packages (TO‑220AB, ISOWATT220AB, TO‑220FPAB, DPAK) and feature ultra‑fast, soft, noise‑free recovery.
Key specifications include a repetitive peak reverse voltage of 300 V, average forward current up to 10 A, maximum junction temperature of 175 °C, and a reverse recovery time as low as 35 ns. Detailed mechanical dimensions and footprint data are provided for each package type.
