STPS2H100U

Single Diodes Overview

The STPS2H100U is a single-chip Schottky rectifier manufactured by STMicroelectronics, designed for high-frequency miniature switched-mode power supplies. It features a 100 V repetitive peak reverse voltage (Vrrm) and a continuous forward current (If) of 2 A. The device utilizes silicon technology in an SMB (DO-214AA) surface-mount package. Key electrical parameters include a maximum forward voltage (Vf) of 880 mV at rated current and a low reverse leakage current (Ir) of 1 µA. It supports a non-repetitive peak forward surge current (Ifsm) of 75 A and operates within a junction temperature range from -65 °C to +175 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix 'U' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with SMB (DO-214AA) footprint requirements during PCB layout. Confirm RoHS compliance status via the latest product change notification or datasheet revision history before finalizing procurement.

Single Diodes Selection Notes

Select this component when a single Schottky diode with 2 A current rating and 100 V blocking voltage is required in an SMB package. Consider the specified Vf and Ir characteristics for efficiency calculations in low-voltage output stages. Verify that the 75 A surge current rating meets the circuit's inrush requirements. Compare thermal performance against alternative packages if space constraints allow.

Single Diodes Part Context

The STPS2H100U belongs to the STPS2H100 series of Power Schottky Rectifiers from STMicroelectronics. This series is engineered for compact power conversion designs where size and switching speed are critical. The device represents a standard solution for general-purpose rectification in consumer electronics and industrial power supplies requiring reliable high-frequency operation.

Single Diodes Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as STPS2H100, ensuring identical electrical ratings and package dimensions. Verify that any substitute maintains the same avalanche capability and thermal characteristics. Cross-reference datasheets to confirm equivalent forward voltage and leakage current specifications.
