Summary of OM4001ST / OM4002ST Schottky Rectifiers Datasheet

The OM4001ST and OM4002ST Schottky Rectifiers are designed for high density and high power applications where a compact, lightweight, and reliable solution is required. These rectifiers are characterized by their small size, low forward voltage, and very fast switching time. They are packaged in a small hermetic isolated metal package, enabling ease of use and providing low thermal resistance. The rectifiers’ isolated package design offers additional utility and versatility.

The OM4001ST and OM4002ST are differentiated by their peak inverse voltages, with the OM4001ST rated at 45V and the OM4002ST at 60V. Both devices can handle a maximum average DC output current of 15A at a case temperature of 100°C and are capable of withstanding a peak surge current of 150A for an 8.3ms non-repetitive pulse.
