BAT54S,235

Overview

The BAT54S,235 is a planar Schottky barrier diode from Nexperia, encapsulated in an SOT-23 (TO-236AB) surface-mount package. It features a dual series configuration with two cathodes and one common anode. Key electrical parameters include a maximum repetitive peak reverse voltage of 30 V and a maximum continuous forward current of 200 mA. The device exhibits a low forward voltage of 800 mV at 100 mA and a peak reverse recovery time of 5 ns. It supports a non-repetitive peak forward surge current of 600 mA and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual series configuration with integrated guard ring for stress protection
• Low forward voltage characteristics for efficient signal handling
• Low capacitance design suitable for high-speed switching applications

Applications

• Ultra high-speed switching circuits
• Line termination in communication systems
• Voltage clamping for signal protection
• Reverse polarity protection in portable devices

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm pinout and internal configuration. The BAT54S designation indicates a series arrangement; ensure this matches the circuit topology requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a dual-diode solution with series connection is required in a compact SOT-23 footprint. The low capacitance and fast recovery time make it appropriate for high-frequency signal processing. Ensure the 30 V reverse voltage rating exceeds the maximum expected line voltage in the target application environment.

Part Context

This component belongs to the Nexperia BAT54 family of small-signal Schottky diodes. These devices are designed for general-purpose rectification and signal mixing in consumer electronics and industrial equipment. The SOT-23 package provides a space-saving solution for modern printed circuit board layouts requiring multiple diode functions.

Replacement Considerations

BAT54S,215: Identical electrical specifications and configuration; differs only in reel packaging quantity.
