BAT54W

Single Diodes Overview

The BAT54W is a single Schottky barrier diode manufactured by Diotec Semiconductor in an SOT-323 surface-mount package. It features a repetitive peak reverse voltage of 30 V and a maximum average forward current of 200 mA. The device exhibits a low forward voltage drop, typically less than 1000 mV at 100 mA, with a maximum leakage current of 3 µA at 30 V reverse bias. Operating temperatures range from -55°C to +150°C junction temperature.

Single Diodes Feature Summary

• Ultra-small surface mount package designed for space-constrained applications
• Fast switching capability with reverse recovery time under 5 ns
• Low forward voltage drop for improved efficiency
• PN junction guard ring provides protection against transients and ESD

Single Diodes Applications

• High-speed switching circuits
• Voltage clamping applications
• Polarity protection
• RF mixing and detection

Single Diodes Procurement Notes

Verify the specific manufacturer datasheet before integration, as electrical characteristics such as forward voltage and leakage current can vary between suppliers. Confirm that the component meets the required AEC-Q101 standards if automotive reliability is necessary. Ensure the ordering suffix matches the exact packaging and qualification grade specified in your design documentation.

Single Diodes Selection Notes

Select this component when a single Schottky diode configuration is required in a compact SOT-323 footprint. It is suitable for designs prioritizing low forward voltage and fast switching speeds over high current handling. Compare thermal resistance values against your board's copper pad area to ensure adequate heat dissipation within the specified operating temperature range.

Single Diodes Part Context

This part belongs to the BAT54 series of small signal Schottky diodes produced by Diotec Semiconductor. The series includes variants like BAT54AW, BAT54CW, and BAT54SW, which differ primarily in internal configurations such as dual common anode or common cathode setups. The BAT54W specifically denotes the single-diode version within this family.
