DIOSS34
Overview
The SS34 is a surface-mount Schottky barrier rectifier designed for high-current power management applications. Housed in a standard SMC (DO-214AB) package, it provides a maximum average rectified output current of 3A and a peak repetitive reverse voltage rating of 40V. This diode is characterized by low power loss, high efficiency, and high surge current capability, making it suitable for high-frequency switching and low-voltage applications.
Why Choose This Part
The SS34 offers a high 3A current rating in a relatively compact SMC footprint, facilitating higher power density in power supply designs. Its Schottky construction ensures fast switching speeds and a low forward voltage drop, which minimizes heat generation and maximizes system efficiency. With an operating temperature range of -55C to +150C, it is reliable in demanding thermal environments.
Applications
Key Specifications
Getting Started
When integrating the SS34, ensure that the PCB land pattern provides sufficient copper area for the SMC package to facilitate heat dissipation at the 3A maximum current rating. Engineers should verify that the 40V peak reverse voltage exceeds the highest expected voltage spikes in their system, accounting for inductive ringing. Consult the Diodes Incorporated datasheet for forward current derating curves relative to lead temperature to ensure long-term reliability.
