SRS1090

Diode Arrays Overview

The SRS1090 is a dual common cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It integrates two independent silicon Schottky diodes within a single D2PAK (TO-263AB) surface-mount package. The device is rated for a continuous forward current of 5 amperes per element and withstands a maximum repetitive peak reverse voltage of 90 volts. Designed for low power loss applications, it features a maximum non-repetitive peak forward surge current capability of 120 amperes. The component operates reliably across an extended junction temperature range from -55°C to +150°C.

Diode Arrays Feature Summary

• Dual common cathode configuration integrating two elements in one package
• Low forward voltage drop characteristic for enhanced efficiency
• Surface-mount D2PAK packaging for automated assembly

Diode Arrays Applications

• DC-DC converter circuits
• Power supply output rectification
• Free-wheeling diode applications in inductive loads

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and marking codes. Ensure the procurement channel provides traceability documentation compliant with RoHS directives. Confirm that the received components match the JEDEC-95 TO-263AB mechanical dimensions specified in the technical data sheet prior to integration into the design.

Diode Arrays Selection Notes

Select this component when a compact dual-diode solution is required for high-efficiency power conversion. The D2PAK package offers superior thermal dissipation compared to smaller surface-mount options. Verify that the 90V reverse voltage rating exceeds the maximum circuit transient voltages. Consider the 5A continuous current rating relative to the expected load profile and ambient operating temperatures to ensure adequate thermal headroom.

Diode Arrays Part Context

This part belongs to the SRS series of surface mount Schottky barrier rectifiers produced by Taiwan Semiconductor. The series utilizes advanced silicon planar technology to achieve fast switching characteristics and low leakage current. The D2DPAK form factor is standard for medium-power applications requiring robust solder joint reliability and efficient heat transfer to the printed circuit board copper planes.

Diode Arrays Replacement Considerations

Cross-reference with other dual common cathode Schottky rectifiers in the D2PAK package offering identical 5A and 90V ratings. Verify pinout compatibility and thermal resistance specifications before substitution.
