SB320

Single Diodes Overview

The SB320 is a Schottky barrier rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose applications. It features an average forward current (IFAV) of 3 A and a repetitive peak reverse voltage (VRRM) of 20 V. The device exhibits a maximum forward voltage (VF) of less than 0.49 V at 3.0 A and 25°C junction temperature. Reverse leakage current is specified as less than 0.5 mA at VR = VRRM and 25°C. The component supports a peak forward surge current (IFSM) of 87 A under 50 Hz half-sine-wave conditions and operates within a junction temperature range of -50°C to +150°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration, such as bulk or tape-and-reel formats. Confirm that the requested quantity aligns with standard shipping units defined by Diotec Semiconductor. Ensure compliance with export control regulations if applicable to your region. Always request the latest datasheet version prior to final design integration to account for potential product updates.

Single Diodes Selection Notes

Select the SB320 when a 3 A continuous current rating and 20 V blocking voltage are required for efficient power conversion. Consider this component for designs prioritizing low conduction losses due to its sub-0.5 V forward voltage characteristic. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance. Ensure the operating environment remains within the -50°C to +150°C junction temperature limits for reliable performance.

Single Diodes Part Context

The SB320 belongs to the SB3xx series of Schottky Barrier Rectifiers produced by Diotec Semiconductor. This series offers various voltage ratings while maintaining a consistent 3 A average forward current capability. The devices are engineered for high efficiency and reliability in compact form factors. They represent a standard solution for modern electronics requiring robust rectification with minimal power dissipation.

Single Diodes Replacement Considerations

Cross-reference alternative part numbers only if they match the exact electrical specifications: 3 A IFAV, 20 V VRRM, and DO-201 package. Verify compatibility regarding forward voltage and leakage current tolerances. Ensure any substitute component meets the same thermal and mechanical requirements for direct replacement.
