BAT54ZFILM Description

The BAT54ZFILM from STMicroelectronics is a Schottky barrier diode designed for high-efficiency rectification in fast-switching circuits. Packaged in a compact SOD123 surface-mount form factor, it delivers 40V reverse voltage (Vr) and 300mA average rectified current (Io), making it suitable for low-power, high-speed applications. With an ultra-fast reverse recovery time (trr) of just 5ns and low forward voltage drop (900mV @ 100mA), it minimizes power losses and improves thermal performance. Its low capacitance (10pF @ 1V, 1MHz) ensures minimal signal distortion in high-frequency circuits.

BAT54ZFILM Features

• Fast Recovery: ≤500ns recovery speed, ideal for switching applications (>200mA).
• Low Leakage: 1µA @ 30V reverse leakage ensures energy efficiency.
• High-Speed Performance: 5ns trr enables use in RF and fast-switching designs.
• Compact & Reliable: SOD123 package with MSL1 (Unlimited) moisture sensitivity, suitable for automated assembly.
• Compliance: ROHS3 and REACH Unaffected, meeting environmental standards.
• Low Capacitance: 10pF reduces high-frequency noise, critical for signal integrity.

BAT54ZFILM Applications

• Power Management: DC-DC converters, voltage clamping, and reverse polarity protection.
• High-Frequency Circuits: RF detectors, mixers, and signal demodulation.
• Portable Electronics: Smartphones, wearables, and IoT devices due to low power loss.
• Automotive Systems: Infotainment and LED drivers where fast switching is essential.
• Industrial Controls: Snubber circuits and freewheeling diodes in motor drives.

Conclusion of BAT54ZFILM

The BAT54ZFILM stands out for its ultra-fast switching, low forward voltage, and compact design, making it a superior choice for high-efficiency rectification in space-constrained applications. While obsolete, its performance metrics—such as 5ns recovery time and low leakage—remain competitive for legacy designs or replacements. Ideal for high-frequency, low-power systems, it balances speed, efficiency, and reliability in modern electronics.
