MMBD717LT1G

Overview

The onsemi MMBD717LT1G is a surface-mount Schottky barrier diode housed in a compact SOT-23 package. It features a common anode configuration with two internal diodes, designed for low-voltage signal processing and rectification. Key electrical specifications include a maximum repetitive peak reverse voltage (Vrrm) of 40 V and a continuous forward current (If) of 10 mA per diode. The device exhibits a low forward voltage drop and fast switching characteristics, making it suitable for high-frequency applications. It operates within a temperature range of -55°C to +150°C and complies with RoHS standards.

Procurement Notes

Verify the complete part number including the LT1G suffix to ensure correct packaging and tape-and-reel specifications. Confirm compliance requirements such as RoHS and halogen-free status match project needs. Check for automotive qualification if used in vehicle systems. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to prevent package damage during soldering.

Selection Notes

Select this component when a small form factor is required for dual-diode functions. Compare forward voltage drops against alternative Schottky diodes for efficiency optimization. Consider the 40 V rating relative to system voltage peaks to avoid breakdown. Evaluate thermal performance under continuous load conditions given the small SOT-23 footprint.

Part Context

This component belongs to onsemi's MMBD series of small-signal Schottky diodes. The series offers various configurations including common cathode and common anode setups. These diodes are widely used in portable electronics due to their low profile and fast recovery times. The MMBD717 variant specifically targets applications requiring dual diodes in a single package to reduce board space.

Replacement Considerations

Publicly confirmed substitute part numbers were not identified in verified documentation. Verify pin compatibility and electrical ratings before considering any cross-reference. Ensure any replacement maintains the common anode configuration and SOT-23 package dimensions.
