LLSD103A-7

Single Diodes Overview

The LLSD103A-7 is a surface mount Schottky barrier diode manufactured by Diodes Incorporated, housed in a MiniMELF glass package. It features a peak repetitive reverse voltage of 40 V and a forward continuous current rating of 350 mA. The device exhibits a maximum forward voltage drop of 600 mV at 200 mA and a peak reverse current of 5 µA at 30 V. Key electrical parameters include a total capacitance of 50 pF and a reverse recovery time of 10 ns. Power dissipation is rated at 400 mW with a thermal resistance of 250 °C/W. Operating temperature ranges from -55 °C to +125 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging quantity and reel specifications. Ensure the component matches the MiniMELF form factor and RoHS compliance status required for the target assembly process. Cross-reference the datasheet revision number to validate current electrical characteristics before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 40 V reverse voltage rating and 350 mA continuous current are required in a compact MiniMELF package. Consider the low forward voltage and fast recovery characteristics for efficiency-critical designs. Evaluate the thermal resistance and power dissipation limits relative to the expected ambient temperature and board layout constraints.

Single Diodes Part Context

This part belongs to the LLSD103 series, which includes variants with different reverse voltage ratings such as the LLSD103B (30 V) and LLSD103C (20 V). All variants share the same physical MiniMELF package and similar electrical characteristics regarding forward current and power dissipation, differing primarily in their blocking voltage capabilities.

Single Diodes Replacement Considerations

Direct substitutes within the same family include LLSD103B-7 and LLSD103C-7, provided the circuit voltage requirements align with their lower ratings. Verify that any alternative Schottky diode maintains compatible package dimensions and thermal performance.
