DST5100S

Single Diodes Overview

The Littelfuse DST5100S is a single Schottky barrier rectifier housed in a TO-277B surface-mount package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward current rating of 5 A per device at a case temperature of 125°C. The component supports a peak one-cycle non-repetitive surge current of 120 A. Electrical characteristics include a typical forward voltage drop of 0.69 V at 5 A and 25°C junction temperature, with a maximum reverse current of 0.12 mA at rated voltage and 25°C. The junction temperature range spans from -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm terminal finish material and packing mode. The standard designation corresponds to Pb-free E3 interconnects with tin terminals. Confirm reel quantities match project requirements, as the standard packing option is 5000 pieces per reel. Ensure compatibility with RoHS and REACH regulations before finalizing procurement.

Single Diodes Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-frequency circuits. The TO-277B package provides a compact footprint suitable for surface-mount assembly. Verify thermal management capabilities, as the device relies on PCB pad areas for heat dissipation during continuous operation. Ensure the operating environment stays within the specified junction temperature limits to maintain performance reliability.

Single Diodes Part Context

This part belongs to the Littelfuse DST series of Ultra Low VF Schottky Barrier Rectifiers. The series is engineered to meet commercial and industrial application requirements by offering high temperature stability and low leakage currents. The naming convention indicates a 5A forward current rating and 100V reverse voltage capability within the single-diode TO-277B form factor.

Single Diodes Replacement Considerations

Direct substitutes must match the 5A current rating, 100V reverse voltage, and TO-277B package dimensions. Verify that alternative components offer comparable forward voltage drops and thermal resistance values to ensure circuit performance equivalence without redesign.
