MMDL101T1G

RF Diode Overview

The MMDL101T1G is a single Schottky barrier rectifier manufactured by onsemi, utilizing silicon technology. It is housed in an SOD-323 surface-mount package designed for compact circuit layouts. The device supports a maximum repetitive peak reverse voltage of 7 V and conducts a forward current of 10 mA. Key electrical characteristics include a maximum forward voltage drop of 600 mV and a low reverse leakage current of 250 nA. It operates reliably within a temperature range from -55 °C to +150 °C junction temperature.

RF Diode Feature Summary

• Schottky barrier construction ensures fast switching speeds and minimal reverse recovery time.
• Low forward voltage drop contributes to improved system efficiency.
• Small SOD-323 footprint facilitates automated assembly and space-constrained designs.

RF Diode Applications

• High-frequency signal detection and mixing circuits
• Power supply clamping and protection stages
• Low-voltage DC-DC converter freewheeling paths

RF Diode Procurement Notes

Verify the component authenticity through official onsemi channels or authorized distributors. Confirm that the ordering suffix matches the required tape and reel specifications. Ensure compliance with RoHS directives and check for any specific handling requirements related to moisture sensitivity levels before storage and reflow soldering processes.

RF Diode Selection Notes

Select this component when a low-capacitance, fast-recovery diode is required for signals below 7 V reverse bias. Compare the 10 mA current rating against peak load requirements. Consider the SOD-323 thermal dissipation limits if operating near the maximum junction temperature threshold in enclosed environments.

RF Diode Part Context

This part belongs to the MMDL series of small-signal Schottky diodes from onsemi. It shares functional similarities with other members like the MMDL100T1G but offers specific voltage and current ratings tailored for low-power signal processing applications. The series is widely used in consumer electronics and industrial control systems requiring reliable rectification at low voltages.

RF Diode Replacement Considerations

Direct substitutes may include the MMBD101LT1G in an SOT-23 package or the BAS40 in similar small outlines. Verify pinout compatibility and ensure the replacement meets the 7 V reverse voltage and 10 mA forward current specifications. Thermal performance differences between SOD-323 and alternative packages should be evaluated during PCB layout adjustments.
