SMMBD701LT1

RF Diode Overview

The SMMBD701LT1 is a surface-mount Schottky barrier diode manufactured by onsemi. It features a single diode configuration housed in an SOT-323 package with three terminals. The device supports a peak reverse repetitive voltage (Vrrm) of 70 V and a maximum continuous forward current (If) of 10 mA. Key electrical parameters include a peak reverse current (Ir) of 200 nA, a maximum forward voltage (Vf) of 1 V, and a power dissipation rating of 280 mW. The component operates within a junction temperature range of -55°C to +125°C and complies with RoHS and Pb-Free standards.

RF Diode Feature Summary

• Schottky barrier technology for low forward voltage drop
• Compact SOT-323 surface-mount packaging
• High thermal stability up to 125°C junction temperature

RF Diode Applications

• DC-DC converter output rectification
• Power supply freewheeling applications
• Low voltage signal detection circuits

RF Diode Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compliance with current environmental directives such as RoHS before integration into production designs.

RF Diode Selection Notes

Select this component for applications requiring low forward voltage and fast switching characteristics in space-constrained designs. Confirm that the 10 mA current rating meets the circuit requirements and that the 70 V reverse voltage provides adequate margin for the operating environment.

RF Diode Part Context

This part belongs to the MBD701 series of small-signal Schottky diodes from onsemi. It shares core electrical characteristics with variants like the MMBD701LT1 but utilizes the SOT-323 package for different footprint requirements. The series is designed for general-purpose rectification and switching tasks.

RF Diode Replacement Considerations

Direct substitutes may include the MMBD701LT1G if the SOT-23 package is acceptable. Verify pinout compatibility and thermal performance when considering alternative packages or manufacturers.
