Single Diodes Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is limited to existing stock or surplus channels. Verify the specific revision and packaging details against the original datasheet before integration, as lifecycle status may affect long-term supply continuity and support availability.

Single Diodes Selection Notes

Select this part for designs requiring a 120 V, 30 A Schottky rectifier in a TO-220AB package. Ensure thermal management accommodates the 150°C maximum junction temperature. Consider the obsolete status when planning for production longevity. Verify that the 950 mV forward voltage drop meets the efficiency requirements of the target circuit application.

Single Diodes Part Context

The STPS30SM120ST belongs to the ECOPACK®2 series of power Schottky rectifiers from STMicroelectronics. This series focuses on high reliability and environmental compliance. The device is designed for through-hole assembly, providing mechanical stability for higher current applications compared to surface-mount alternatives in similar voltage classes.

Single Diodes Replacement Considerations

The STPS20M120SR is documented as a similar substitute part number. Note that the substitute offers a 20 A rating compared to the 30 A rating of the primary model. Verify current handling capabilities and package compatibility (I2PAK vs TO-220AB) during replacement evaluation.
