SD101CW-HE3_A-18

Single Diodes Overview

The SD101CW-HE3_A-18 is a small signal Schottky diode manufactured by Vishay Semiconductors. It features a metal-on-silicon barrier protected by a PN junction guard ring in an SOD-123 surface-mount package. The device is AEC-Q101 qualified and RoHS-compliant. Key electrical parameters include a repetitive peak reverse voltage of 40 V, a forward continuous current of 100 mA, and a maximum single cycle surge current of 2 A. Forward voltage drop is typically 900 mV at 15 mA, with a leakage current of 200 nA at 30 V.

Single Diodes Feature Summary

• Low forward voltage drop and fast switching characteristics suitable for protection of MOS devices
• Metal-on-silicon Schottky barrier technology protected by a PN junction guard ring
• Molding compound meets UL 94 V-0 flammability rating

Single Diodes Applications

• Steering, biasing, and coupling diodes for fast switching applications
• Protection circuits for low logic level applications
• General purpose applications requiring fast recovery

Single Diodes Procurement Notes

Verify the specific HE3_A suffix indicates AEC-Q101 automotive qualification rather than commercial grade. Confirm the -18 packaging code corresponds to 10,000 units per 13-inch reel. Ensure the component matches the SOD-123 footprint dimensions provided in the mechanical data section before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 40 V reverse voltage rating is required alongside high-speed switching capabilities. The SOD-123 package offers a compact solution for space-constrained designs. Consider the thermal resistance values if operating near the maximum junction temperature limit of 125 °C under continuous load conditions.

Single Diodes Part Context

This part belongs to the SD101 series of small signal Schottky diodes from Vishay. The series includes variants with different voltage ratings such as the SD101AW (60 V) and SD101BW (50 V). All variants share similar physical dimensions and switching characteristics but differ in their breakdown voltage specifications.

Single Diodes Replacement Considerations

SD101CW-E3-18 is a commercially graded alternative within the same series that lacks AEC-Q101 qualification.
