BAT54S

BAT54S Description

The BAT54S from Diotec Semiconductor is a Schottky diode array configured as 1 pair series connection, housed in a compact SOT-23 surface-mount package. Designed for small-signal applications with currents up to 200mA (Io), it offers low forward voltage drop (1V max @ 100mA) and fast switching with a reverse recovery time (trr) of just 5 ns. Its 30V maximum reverse voltage (Vr) and low reverse leakage current (2µA @ 25V) make it suitable for precision circuits. The device is RoHS non-applicable and compliant with EAR99 export regulations, supplied in Tape & Reel (TR) packaging for automated assembly.

BAT54S Features

• Schottky Technology: Ensures low power loss and high efficiency in switching applications.
• Fast Switching (5 ns trr): Ideal for high-frequency circuits, such as RF detection or signal clamping.
• Low Vf (1V @ 100mA): Reduces heat dissipation, improving energy efficiency.
• 30V Reverse Voltage: Provides robust protection in low-voltage systems.
• Compact SOT-23 Package: Saves PCB space while enabling surface-mount assembly.
• Series-Connected Pair: Simplifies circuit design for dual-diode configurations like OR-ing or polarity protection.

BAT54S Applications

The BAT54S excels in:

• Signal Demodulation & RF Detection: Due to its fast switching and low capacitance.
• Voltage Clamping & Protection Circuits: Protects sensitive ICs from transient spikes.
• Power OR-ing & Redundant Power Supplies: Leverages its series-connected dual-diode structure.
• Portable Electronics: Low Vf and small footprint suit battery-powered devices.
• High-Speed Switching Logic: Used in digital circuits for signal conditioning.

Conclusion of BAT54S

The BAT54S is a high-performance Schottky diode array optimized for fast switching, low-loss applications. Its compact SOT-23 package, low forward voltage, and 5 ns recovery time make it superior to standard PN diodes in high-frequency or efficiency-critical designs. Whether used in RF systems, power management, or signal processing, the BAT54S delivers reliable performance with minimal footprint, aligning with modern electronics miniaturization trends. Engineers favor it for cost-effective, space-constrained solutions requiring speed and efficiency.
