SS30-E

Overview

The Sanyo SS30-E is a surface mount Schottky barrier rectifier diode manufactured by Sanyo Semicon Device. It features a single-element silicon construction designed for high-speed switching applications. The device is housed in the R-1 package, which is a small outline plastic case suitable for automated surface mounting processes. Key electrical characteristics include a maximum repetitive peak reverse voltage range of 20 to 60 volts and a continuous forward current rating of 1.0 ampere. The component is engineered to provide low forward voltage drop and minimal reverse leakage current, ensuring efficient power conversion in compact electronic designs.

Feature Summary

• Schottky barrier technology enables fast switching speeds and low forward voltage drop
• Silicon planar construction ensures high reliability and stable performance
• Surface mount R-1 package facilitates automated assembly and space-saving design

Applications

• DC-DC converter circuits
• Free-wheeling diodes in inductive load protection
• Polarity protection in power supply inputs
• High-frequency rectification in consumer electronics

Procurement Notes

Verify the specific voltage sub-rating (20V, 30V, or 60V) required for the application, as the SS30 series encompasses multiple variants within this designation. Confirm that the R-1 package dimensions align with the PCB footprint specifications. Ensure compliance with RoHS directives if environmental regulations apply to the final product assembly. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles and storage conditions.

Selection Notes

Select the SS30-E variant based on the maximum reverse voltage present in the circuit to prevent breakdown. Consider the thermal management requirements, as the small R-1 package has limited heat dissipation capabilities compared to larger through-hole components. Evaluate the forward current demands to ensure the 1.0A rating provides adequate margin for peak loads. Compare alternative Schottky diodes from other manufacturers if specific pinout compatibility or enhanced surge current ratings are necessary for the design.

Part Context

The SS30-E belongs to the broader SS30 family of Schottky rectifiers produced by Sanyo Semicon Device. This series is widely utilized in general-purpose power supply applications where efficiency and size are critical. The E suffix typically denotes a specific tape-and-reel packaging configuration or a particular voltage grade within the standard SS30 lineup. These devices complement Sanyo's portfolio of discrete semiconductors aimed at improving energy efficiency in portable and desktop electronic systems.

Replacement Considerations

Direct substitutes include the SS30 series from Rectron Semiconductor and the 1S30 series from Formosa Moschip. Other compatible alternatives include the MBRS320T3G from ON Semiconductor and the SR360 from Vishay. When replacing, verify that the replacement part matches the R-1 package outline and maintains equivalent electrical parameters for reverse voltage and forward current.
