SMS1515-08H04

Overview

The SMS1515-08H04 is a surface-mount Schottky barrier rectifier manufactured by BeStar Technologies, Inc. It features a single diode configuration housed in an SOD-323 package. The device is rated for a maximum average forward rectified current of 150 mA and a repetitive peak reverse voltage of 80 V. Key electrical characteristics include a low forward voltage drop of approximately 1.0 V at the rated current and a maximum reverse leakage current of 5 µA at full rated voltage. The component supports a maximum operating junction temperature of 150 °C and is designed for high-speed switching applications requiring minimal recovery time.

Feature Summary

• Low forward voltage drop for improved power efficiency
• High-speed switching capability with low reverse recovery charge
• Robust construction for reliable operation in compact designs

Applications

• DC-DC converter output rectification
• Power supply freewheeling diodes
• Reverse polarity protection circuits

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact tape-and-reel quantity and packaging format required for your assembly line. Ensure that the requested part number matches the standard SOD-323 footprint dimensions and pinout configuration compatible with your PCB layout. Confirm RoHS compliance status if environmental regulations apply to your final product assembly process.

Selection Notes

Select this component when designing circuits that require a compact solution for low-current rectification tasks. The 150 mA current rating makes it suitable for signal processing or auxiliary power rails rather than main power paths. Consider the thermal dissipation capabilities of the SOD-323 package relative to the ambient temperature conditions of the final enclosure to ensure long-term reliability under continuous load.

Part Context

This component belongs to the general category of small-signal Schottky diodes used in consumer electronics and industrial control systems. It serves as a fundamental passive semiconductor element for converting alternating current to direct current or protecting sensitive components from voltage spikes. Its small form factor allows for high-density board layouts common in modern portable devices.

Replacement Considerations

Substitute parts must match the 80 V reverse voltage, 150 mA forward current, and SOD-323 package type. Verify that alternative manufacturers offer comparable forward voltage and leakage specifications to maintain circuit performance integrity.
