BAT54S

BAT54S Description

The BAT54S from MDD is a Schottky diode array configured as 1 pair series connection, designed for high-efficiency, low-power applications. It features a 30V maximum reverse voltage (Vr) and a forward voltage (Vf) of 1V at 100mA, ensuring minimal power loss. With a reverse recovery time (trr) of just 5ns, it excels in high-speed switching circuits. The device is housed in a compact SOT-23 package, making it ideal for space-constrained designs. Compliant with ROHS3 and REACH standards, it is suitable for environmentally conscious applications.

BAT54S Features

• Low Forward Voltage (1V @ 100mA): Enhances energy efficiency in power-sensitive designs.
• Ultra-Fast Switching (5ns trr): Ideal for high-frequency applications like signal demodulation and clamping.
• Low Reverse Leakage (2µA @ 25V): Minimizes power dissipation in standby modes.
• 200mA Average Rectified Current (Io): Supports moderate current loads in compact circuits.
• Wide Temperature Range (-55°C to +125°C): Reliable performance in harsh environments.
• Surface-Mount (SOT-23) Package: Enables high-density PCB layouts.
• RoHS3 & REACH Compliant: Meets global environmental standards.

BAT54S Applications

The BAT54S is widely used in:

• Signal Clamping & Protection: Prevents voltage spikes in data lines and I/O ports.
• High-Speed Switching: Suitable for RF detectors, mixers, and DC-DC converters.
• Power Management: Efficient rectification in low-voltage supplies (e.g., portable devices).
• Logic Circuits: Acts as a level shifter or OR-ing diode in digital systems.
• Automotive Electronics: Reliable operation under wide temperature fluctuations.

Conclusion of BAT54S

The BAT54S stands out for its fast switching, low power loss, and compact form factor, making it a versatile choice for modern electronics. Its Schottky technology ensures superior performance over standard PN-junction diodes, particularly in high-speed or efficiency-critical designs. Whether for consumer electronics, automotive systems, or industrial controls, the BAT54S delivers reliability and efficiency in a miniature package.
