• Low leakage current with good trade-off between leakage and forward voltage drop
• ECOPACK 2 compliant

Diode Arrays Applications

• Notebook adapters
• LCD adapters
• Desktop switch mode power supplies (SMPS)

Diode Arrays Procurement Notes

Verify the specific suffix 'CR' against official STMicroelectronics documentation to confirm package variant or tape-and-reel configuration. Ensure compatibility with TO-220AB mounting requirements. Confirm RoHS compliance status via the latest datasheet revision. Validate thermal management needs based on the specified junction temperature capabilities.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling in a dual center-tap configuration. The 120 V rating offers headroom for standard adapter voltages. Consider the TO-220AB package for through-hole mounting and robust thermal dissipation in desktop and portable power supply designs.

Diode Arrays Part Context

This part belongs to the STPS series of dual Power Schottky Rectifiers from STMicroelectronics. It shares the core technology of low forward voltage drop and high reliability typical of the family, specifically tailored for high-frequency rectification in compact power conversion systems.

Diode Arrays Replacement Considerations

Check for direct substitutes within the STPS40120 series with different suffixes indicating package variations. Verify equivalent electrical ratings if considering third-party Schottky rectifiers.
