BAT54S-7-F-2477

Overview

BAT54S-7-F-2477 is a dual Schottky barrier diode array manufactured by Diodes Incorporated. It features a common cathode configuration with two independent silicon elements integrated into a single SOT-23 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 200 mA per diode. Key electrical characteristics include a low forward voltage drop, minimal reverse leakage current, and ultra-fast switching capabilities with a reverse recovery time typically under 5 ns. The component operates within a junction temperature range of -65 °C to +150 °C and dissipates up to 350 mW of power.

Feature Summary

• Dual Schottky barrier diodes integrated in a compact SOT-23 surface-mount package
• Common cathode configuration for efficient circuit layout and space saving
• Ultra-fast switching performance with low reverse recovery time
• Low forward voltage drop to minimize conduction losses

Applications

• High-speed signal switching and logic level clamping
• Power supply protection against reverse polarity and transient voltages
• OR-ing circuits for redundant power input management
• Blocking diodes in battery-powered portable devices

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout compatibility and packaging specifications. Ensure the selected variant matches the required thermal dissipation and voltage ratings for the target application environment. Cross-reference datasheet parameters with system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a small form factor is required for dual Schottky applications. The common cathode arrangement simplifies PCB routing compared to discrete solutions. Evaluate thermal constraints carefully, as the SOT-23 package has limited heat dissipation capacity. Confirm that the 30 V reverse voltage rating exceeds the maximum expected circuit voltage including transients.

Part Context

The BAT54S belongs to a widely used family of small-signal Schottky diodes designed for high-efficiency rectification and switching. Variants within the series differ primarily in internal connection schemes, such as common anode or series configurations. This specific model represents the common cathode version, distinguishing it from other BAT54 derivatives like the BAT54A or BAT54C.

Replacement Considerations

Compatible substitutes include BAT54S from other manufacturers such as ON Semiconductor or Vishay, provided they adhere to the same SOT-23 footprint and electrical specifications. Verify pinout alignment and thermal characteristics before substitution.
