Product Description

Product Overview

The SF31G THRU SF38G series are 3.0A Axial Super Fast Rectifiers designed for through-hole mounting. These devices feature a glass-passivated chip junction structure, high current capability, and high surge capability, making them suitable for switching mode applications. They are available in voltage ratings from 50V to 600V. The rectifiers are housed in a DO-201AD epoxy case with UL94-V0 rated flame retardant properties and axial leads solderable per MIL-STD-202, Method 208. Lead-free parts meet RoHS requirements, and a suffix "-H" indicates Halogen-free parts.
