BAT42W-G3-08

Single Diodes Overview

The BAT42W-G3-08 is a small signal Schottky diode manufactured by Vishay Semiconductors. It features a repetitive peak reverse voltage of 30 V and a forward continuous current rating of 300 mA. The device exhibits a maximum reverse leakage current of 0.5 µA at 25 V and a typical forward voltage of 1000 mV at 200 mA. Electrical characteristics include a reverse recovery time of 5 ns and a diode capacitance of 7 pF at 1 V. Thermal resistance from junction to ambient air is 420 K/W on an FR-4 board. The component operates within a temperature range of -55 °C to +125 °C and utilizes the SOD-123 surface-mount package.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching capabilities for general purpose applications
• Incorporates a PN junction guard ring to provide protection against excessive voltage such as electrostatic discharges
• Molding compound meets UL 94 V-0 flammability rating

Single Diodes Applications

• Protection against electrostatic discharge

Single Diodes Procurement Notes

Verify the specific part number BAT42W-G3-08 against official Vishay documentation to confirm active status and compliance with RoHS directives. Ensure that the ordering suffix corresponds to the required packaging configuration, specifically the 3000 units per reel option in 8 mm tape on a 7-inch reel. Cross-reference thermal management requirements with the specified thermal resistance values before finalizing procurement specifications.

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 current handling capacity and physical footprint. Consider the 30 V reverse voltage limit and 300 mA continuous forward current ratings to ensure adequate margins for the intended circuit conditions and operating temperatures.

Single Diodes Part Context

This component belongs to the BAT42W-G series of small signal Schottky diodes produced by Vishay General Semiconductor - Diodes Division. The series is designed for high-efficiency rectification and switching tasks where low power loss is critical. The G3 designation indicates a green, commercial grade product compliant with environmental standards.

Single Diodes Replacement Considerations

BAT43W-G3-08 shares the same SOD-123 package and electrical ratings but features a lower forward voltage characteristic.
