BAT42WS

Single Diodes Overview

The BAT42WS is a single Schottky barrier diode manufactured by Taiwan Semiconductor Corporation, housed in an SOD-323F surface-mount package. It features a peak repetitive reverse voltage of 30 V and a maximum RMS reverse voltage of 21 V. The device supports a continuous forward current of 0.2 A with a maximum surge current rating of 4 A. At the rated current, the forward voltage drop is specified at 1 V. The component utilizes silicon technology and includes a PN junction guard ring structure for enhanced reliability.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, such as reel quantities or tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by the design. Cross-reference the manufacturer part number with official datasheets to confirm the exact electrical ratings and package dimensions before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for designs requiring low forward voltage drop and fast recovery times in compact spaces. The SOD-323F package suits high-density PCB layouts. Verify that the 30 V reverse voltage rating exceeds the maximum circuit operating voltage. Consider the 0.2 A current limit when sizing for load requirements.

Single Diodes Part Context

This device belongs to the Schottky barrier diode family from Taiwan Semiconductor. It is designed for general-purpose switching and rectification where speed and low loss are critical. The BAT42WS shares functional similarities with other small-signal Schottky diodes but is distinguished by its specific voltage and current ratings within the SOD-323F form factor.

Single Diodes Replacement Considerations

Check for direct substitutes like the BAT43WS which may share similar physical dimensions but differ in electrical parameters. Verify compatibility with existing footprints and ensure replacement parts meet the same thermal and electrical specifications.
