BAT42W-E3-08

Single Diodes Overview

The BAT42W-E3-08 is a small signal Schottky diode manufactured by Vishay Semiconductors. It features a single circuit configuration in an SOD-123 package. The device has a repetitive peak reverse voltage of 30 V and a forward continuous current rating of 300 mA. Electrical characteristics include a maximum leakage current of 0.5 μA at 25 V, a typical forward voltage of 400 mV at 10 mA, and a reverse recovery time of 5 ns. Power dissipation is rated at 230 mW on an FR-4 board and 350 mW with an infinite heatsink.

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 drop signal detection

Single Diodes Procurement Notes

Verify the specific ordering code suffix to confirm packaging format. The -08 suffix indicates a 7-inch reel containing 3,000 units on 8 mm tape. Confirm that the commercial grade E3 designation aligns with project requirements, as HE3 variants offer AEC-Q101 qualification. Ensure component authenticity through authorized distribution channels.

Single Diodes Selection Notes

Select this component when a low forward voltage drop and rapid switching speed are required in a compact surface-mount form factor. The SOD-123 package provides a balance between thermal performance and board space efficiency. Consider the 30 V reverse voltage limit and 300 mA current capacity during circuit design to ensure operation within absolute maximum ratings.

Single Diodes Part Context

This part belongs to the BAT42W series of small signal Schottky diodes from Vishay. It shares the same physical package and general electrical profile as the BAT43W, though internal construction differs. The product line emphasizes reliability through guard ring protection and RoHS compliance for modern manufacturing environments.

Single Diodes Replacement Considerations

BAT42W-E3-18 serves as a direct functional substitute with identical electrical specifications but utilizes a 13-inch reel packaging format containing 10,000 units per reel.

Single Diodes FAQ

What is the function of the PN junction guard ring?

The PN junction guard ring protects the device against excessive voltage stresses, specifically providing resistance to electrostatic discharge (ESD) events.

How does the packaging format differ between the -08 and -18 suffixes?

The -08 suffix denotes packaging on a 7-inch reel with 3,000 units per reel, while the -18 suffix indicates packaging on a 13-inch reel with 10,000 units per reel.
