STPS3045CR

Diode Arrays Overview

The STPS3045CR is a dual Power Schottky rectifier from STMicroelectronics, rated for 45 V repetitive peak reverse voltage and 15 A average forward current per diode. Packaged in the I2PAK (TO-262) surface-mount format with three pins, it features a common cathode configuration. Key electrical parameters include a maximum forward voltage of 570 mV at 15 A, a reverse leakage current of 200 µA at 45 V, and a non-repetitive peak surge current capability of 220 A. The device operates within a temperature range of -65°C to +175°C junction temperature.

Diode Arrays Feature Summary

• Extremely fast switching characteristics with negligible switching losses
• Very small conduction losses due to low forward voltage drop
• Avalanche rated for robustness against transient energy events

Diode Arrays Applications

• Switch mode power supplies
• High frequency DC to DC converters
• Low voltage high frequency inverters
• Free wheeling applications
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the received part matches the specific I2PAK package and marking codes. Request original datasheets and compliance documentation to ensure adherence to RoHS standards. Validate lot traceability records prior to integration into production lines.

Diode Arrays Selection Notes

Select this component for designs requiring low forward voltage and high efficiency in synchronous rectification or freewheeling roles. Ensure the thermal management system supports the TO-262 package dissipation requirements. Verify that the circuit voltage spikes remain within the avalanche rating limits to prevent device degradation during operation.

Diode Arrays Part Context

This device belongs to the STPS3045C series of dual center tap Schottky rectifiers. It is designed specifically for applications demanding high efficiency and fast recovery times. The series offers multiple packaging options including TO-220AB, TO-247, and D²PAK, with the CR variant utilizing the I2PAK form factor for surface mount assembly.

Diode Arrays Replacement Considerations
