BAT54S-EVL-CT

Overview

The BAT54S-EVL-CT is a Schottky diode array manufactured by Venkel, housed in a surface-mount SOT-23 (TO-236-3) package with three terminals. It features two diodes configured in a series connection. The component supports a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 200 mA. Key electrical characteristics include a peak non-repetitive forward surge current of 600 mA, a maximum forward voltage of 800 mV, and a peak reverse current of 2 μA. The device operates within a temperature range of -55°C to +125°C and exhibits a peak reverse recovery time of 5 ns.

Feature Summary

• Dual Schottky barrier diodes integrated into a single compact surface-mount package for space-constrained designs.
• Series configuration allows for efficient voltage handling and signal processing in low-power applications.
• Fast switching capability with minimal reverse recovery time ensures high-frequency performance.
• Robust thermal stability and low leakage current support reliable operation across wide temperature ranges.

Applications

• Signal clipping and protection circuits
• High-speed switching applications
• Voltage reference and biasing networks

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel quantity matches your production requirements. Confirm that the SOT-23 footprint aligns with your PCB design guidelines. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dual-series Schottky configuration is required in a small outline transistor package. Consider the 30 V reverse voltage rating and 200 mA current capacity against your circuit's peak loads. Evaluate the 5 ns recovery time for suitability in high-frequency signal paths. Compare thermal dissipation capabilities against your board's heat management strategy.

Part Context

This part belongs to the BAT54 series of Schottky diode arrays, which are widely used for their fast switching speeds and low forward voltage drops. The 'S' designation typically indicates a series configuration, while 'EVL' denotes Venkel's specific product line. The '-CT' suffix specifies the packaging format, ensuring compatibility with automated assembly processes.

Replacement Considerations

Direct substitutes may include other manufacturers' BAT54S variants in SOT-23 packages. Verify pinout compatibility and electrical parameters such as reverse voltage and forward current before substitution. Ensure that any replacement maintains the same series configuration and thermal characteristics to preserve circuit functionality.
