BAT43W-HE3_A-18

Single Diodes Overview

The BAT43W-HE3_A-18 is a small signal Schottky diode manufactured by Vishay Semiconductors, housed in an SOD-123 surface-mount package. It features a repetitive peak reverse voltage of 30 V and a forward continuous current rating of 300 mA. The device exhibits a low forward voltage of 330 mV at 50 mA and a reverse recovery time of 5 ns. It operates within a temperature range of -55 °C to +125 °C and is AEC-Q101 qualified.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching capabilities for general purpose applications
• Protected by a PN junction guard ring against excessive voltage such as electrostatic discharges
• Molding compound meets UL 94 V-0 flammability rating with Moisture Sensitivity Level 1

Single Diodes Applications

• General purpose rectification
• Clamping applications
• Protection against electrostatic discharge

Single Diodes Procurement Notes

Verify the specific ordering code suffix to confirm packaging configuration and qualification status. The HE3_A designation indicates RoHS compliance and AEC-Q101 automotive qualification. Confirm the reel size matches production requirements, as options include 3K or 10K units per reel. Ensure the component meets the required operating temperature range for the target application environment.

Single Diodes Selection Notes

Select this component for circuits requiring low forward voltage drop and rapid switching speeds. The SOD-123 package offers a compact footprint suitable for space-constrained designs. Verify that the 30 V reverse voltage rating provides sufficient margin for the maximum expected reverse bias conditions in the circuit design.

Single Diodes Part Context
