CUHS15F30,H3F

Single Diodes Overview

The CUHS15F30,H3F is a single Schottky barrier diode manufactured by Toshiba Semiconductor and Storage. It features a 30 V repetitive reverse voltage (VRRM) and a 1.5 A average forward rectified current (IF(AV)). The device utilizes a US2H surface-mount package, also identified as USC-2 or SC-76/SOD-323 in some contexts, though US2H is the primary designation for this specific part number. Key electrical parameters include a maximum forward voltage of 550 mV at 1.5 A and a reverse leakage current of 200 µA. It supports a forward surge current of 5 A and operates at junction temperatures up to +125 °C.

Single Diodes Procurement Notes

Verify the exact package marking and datasheet revision when sourcing. Confirm that the US2H package matches your PCB footprint requirements. Ensure compliance with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any specific handling instructions related to ESD sensitivity during assembly.

Single Diodes Selection Notes

Select this component when a 30 V rating and 1.5 A current capacity are required in a small surface-mount form factor. Compare forward voltage specifications against alternative Schottky diodes to ensure efficiency targets are met. Consider the thermal resistance of the US2H package for heat dissipation needs. Verify that the reverse leakage current specifications align with your circuit's standby power constraints.

Single Diodes Part Context

This part belongs to Toshiba's CUS/CUHS series of Schottky barrier diodes. The 'CUS' prefix typically denotes standard Schottky diodes, while 'CUHS' may indicate specific performance variations or packaging updates within the same family. These devices are designed for general-purpose rectification where low forward voltage and fast switching speeds are critical. The series offers various voltage and current ratings to suit different power supply designs.

Single Diodes Replacement Considerations

Direct substitutes include other 30 V, 1.5 A Schottky diodes in compatible packages such as the CUHS15F40,H3F for higher voltage tolerance. Alternative manufacturers offer similar US2H packaged Schottky diodes; verify pinout compatibility and thermal characteristics before substitution.
