MBR120ESFT3G

Single Diodes Overview

The MBR120ESFT3G is a Schottky barrier rectifier manufactured by onsemi. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 20 V. The device utilizes low-profile SOD-128 surface-mount packaging to facilitate automated assembly in compact designs. Key electrical characteristics include a maximum DC blocking voltage of 20 V, a forward voltage drop of 595 mV at 1 A, and a low reverse leakage current of 1 µA at rated voltage. The component supports a maximum operating junction temperature of 175 °C and offers high surge capability with an IFSM rating of 50 A.

Single Diodes Feature Summary

• Low forward voltage drop for improved power efficiency
• Ultra-fast switching action with minimal recovery charge
• High thermal stability and robust surge handling capability

Single Diodes Applications

• DC-DC converters
• Power supply freewheeling diodes
• Reverse battery protection circuits

Single Diodes Procurement Notes

Verify the specific suffix 'T3G' to confirm tape-and-reel packaging and lead-free compliance. Ensure the order matches the exact 'MBR120ESFT3G' designation to avoid confusion with similar voltage or current ratings within the MBR120 series. Confirm RoHS and REACH status against current regulatory requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a low-voltage, high-efficiency rectification solution is required in a small surface-mount footprint. The 20 V rating suits low-side rectification in 5 V or 3.3 V systems. Consider the 1 A continuous current limit and 50 A surge capacity for load transient conditions. Evaluate thermal management needs based on the SOD-128 package's thermal resistance characteristics.

Single Diodes Part Context

This part belongs to onsemi's MBR120 series of Schottky rectifiers, designed for general-purpose power conversion applications. The series offers various voltage ratings and packaging options to accommodate different design constraints. The ESFT variant specifically targets space-constrained consumer and industrial electronics requiring reliable performance in compact form factors.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent parts with matching 1 A, 20 V specifications and SOD-128 packaging. Verify pinout compatibility and thermal performance metrics before replacing. Cross-reference datasheets to ensure reverse leakage and forward voltage parameters meet original design requirements.
