SS14-HF

Single Diodes Overview

The SS14-HF is a surface mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMA (DO-214AC) package. The device supports a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 40 V. Key electrical parameters include a low forward voltage drop of 550 mV at 1 A, a maximum reverse leakage current of 500 uA, and a non-repetitive peak forward surge current capability of 80 A. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Utilizes metal silicon junction technology for majority carrier conduction.
• Incorporates guard ring design for enhanced overvoltage protection.
• Constructed with plastic packaging classified as UL flammability rating 94V-0.

Single Diodes Applications

• Low voltage, high frequency inverters

• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the SS14 part number is widely produced by multiple semiconductor vendors including Taiwan Semiconductor and others. Confirm that the Comchip Technology variant matches the required SMA package dimensions and RoHS compliance status. Ensure the datasheet aligns with the 40 V reverse voltage and 1 A current ratings specified for this particular component.

Single Diodes Selection Notes

Select this component for designs requiring efficient rectification in compact surface mount layouts. The low forward voltage drop contributes to reduced power loss and higher system efficiency. Verify thermal management requirements against the specified operating temperature range and ensure compatibility with standard reflow soldering profiles up to 250°C.

Single Diodes Part Context

This component belongs to the class of surface mount Schottky barrier rectifiers designed for general-purpose switching and rectification. It serves as a discrete semiconductor solution for converting AC to DC or protecting circuits from reverse polarity. The SMA package allows for automated assembly and space-constrained PCB designs.

Single Diodes Replacement Considerations

Direct replacements must match the 40 V reverse voltage, 1 A current rating, and DO-214AC (SMA) footprint. Verify pinout compatibility and thermal characteristics before substitution.
