US 1A … US 1M are ultrafast switching silicon rectifiers for surface mount from Texas Instruments.
The US series from Diotec are ultrafast switching surface‑mount silicon rectifiers designed for high‑speed applications. They are supplied in a plastic SMA (DO‑214AC) case and are typically delivered taped and reeled on a roll.
Key electrical parameters include a nominal forward current of 1 A, repetitive peak reverse voltage ranging from 50 V to 1000 V, and low leakage current (<10 pA at 25 °C). Thermal resistance is specified as less than 70 K/W to ambient and less than 30 K/W to the terminal, supporting reliable operation up to 150 °C junction temperature. This manual is written in German.
