BAT854SW,115

Overview

The BAT854SW,115 is a planar Schottky barrier dual diode manufactured by Nexperia USA Inc. It features an integrated guard ring for stress protection and is encapsulated in a very small SOT323 (SC-70) Surface-Mounted Device plastic package with three leads. The device supports a maximum reverse voltage of 40 V per diode and a forward current of 200 mA. Key electrical characteristics include a maximum forward voltage of 420 mV at 30 mA and a maximum reverse current of 0.5 µA at 25 V. The junction temperature range extends from -65 °C to 150 °C.

Feature Summary

• Very low forward voltage
• Very low reverse current
• Guard ring protected
• Very small SMD plastic package

Applications

• Ultra high-speed switching
• Voltage clamping
• Protection circuits
• Blocking diodes
• Low power consumption applications

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a compact dual Schottky configuration is required for low-power designs. The SOT323 package suits space-constrained PCB layouts. Ensure the application operates within the specified 40 V reverse voltage limit and does not exceed the 200 mA forward current rating. Verify thermal management requirements against the junction-to-ambient thermal resistance for the intended mounting footprint.

Part Context

This part belongs to the Nexperia BAT854 series of Schottky barrier dual diodes. It shares the same functional specifications as the BAT854W but utilizes the SC-70 (SOT323) package instead of larger alternatives. The product data sheet indicates it is a non-automotive qualified product, distinguishing it from automotive-specific variants in the broader family.

Replacement Considerations

BAT854W_SERIES v.1 supersedes earlier versions. Check for automotive-qualified equivalents if AEC-Q101 compliance is required.
