BAT43W-E3-08

Single Diodes Overview

The BAT43W-E3-08 is a small signal Schottky diode manufactured by Vishay Semiconductors. It features a repetitive peak reverse voltage of 30 V and a continuous forward current rating of 300 mA. The device exhibits a maximum forward voltage of 1000 mV at 200 mA and a reverse recovery time of 5 ns. Electrical characteristics include a leakage current of 0.5 μA at 25 V and a diode capacitance of 7 pF at 1 MHz. Thermal resistance from junction to ambient air is 420 K/W on an FR-4 board, with a maximum operating temperature of 125 °C.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching capabilities for efficient signal processing.
• Protected by a PN junction guard ring against excessive voltage events such as electrostatic discharges.
• Molding compound meets UL 94 V-0 flammability rating for enhanced safety compliance.

Single Diodes Applications

• General purpose rectification applications
• High-speed switching circuits
• Low voltage signal detection

Single Diodes Procurement Notes

Verify the specific ordering code suffix to confirm packaging configuration. The -08 suffix indicates units are supplied in 3000 taped units per 7-inch reel. Confirm RoHS compliance status and AEC-Q101 qualification requirements based on the base part number prefix before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a single Schottky diode with a 30 V reverse voltage rating is required. Ensure the application operates within the 300 mA continuous forward current limit. Verify that the SOD-123 surface mount package dimensions align with the target PCB footprint design constraints.

Single Diodes Part Context

This component belongs to the BAT42W/BAT43W series of small signal Schottky diodes. The BAT43W variant specifically offers a lower forward voltage compared to the BAT42W at low currents. Both variants share identical mechanical case styles and thermal characteristics while differing slightly in electrical performance parameters.

Single Diodes Replacement Considerations

BAT43W-E3-18 provides identical electrical specifications but utilizes a 10000 unit tape and reel packaging format instead of the 3000 unit configuration found in the -08 variant.
