SS34 Description

Short technical summary and product information.

The SS34 by MDD is a Schottky Barrier Rectifier designed for surface mounting in a compact SMA (DO-214AC) package. It offers a maximum reverse voltage of 40V and a maximum forward current of 3A.

 

This diode features a low forward voltage drop, typically 0.5V at 3A, contributing to high efficiency and reduced power loss. Its fast switching capability minimizes reverse recovery time, making it suitable for high-frequency applications. The operating temperature range is -55°C to 125°C.

 

Key electrical characteristics include a peak forward surge current of 80A for 8.3ms and a junction capacitance of 500pF at 4V and 1MHz. Reverse leakage current is 0.5mA at 25°C and 20mA at 125°C.

 

Typical applications include power rectification, DC-DC converters, reverse polarity protection, and high-frequency circuits. The surface mount SMA package is suitable for high-density PCB designs.
