STMicroelectronics 40 V 300 mA Schottky Diode Dual 3-Pin SOT-23 BAT54SFILM

STMicroelectronics BAT54SFILM is a high-efficiency dual Schottky diode packaged in a 3-pin SOT-23 surface mount device. It delivers reliable performance with a maximum continuous forward current of 300 mA and a peak reverse repetitive voltage of 40 V. The diode's low forward voltage drop of 900 mV minimizes power dissipation, making it ideal for power-sensitive applications.

This diode operates reliably within a wide temperature range from -40°C to 150°C, supporting harsh industrial and commercial environments. Its fast switching with a peak reverse recovery time of only 5 nanoseconds supports high-frequency switching circuits commonly used in power supplies, rectifiers, and protection circuits.

The compact SOT-23 package measures 2.9 mm in length, 1.3 mm in width, and 0.95 mm in height, suitable for space-constrained PCB designs in electronics manufacturing. The device supports a peak non-repetitive forward surge current of 1 ampere, providing robustness to transient current spikes found in switching applications.

With a very low leakage current of 1 microampere at peak reverse voltage, this diode maintains energy efficiency and reduces heat generation. Its surface mount technology package allows automated placement in volume production, contributing to improved manufacturing throughput and quality.

Typical applications include power management in industrial equipment, consumer electronics, automotive circuits (non-automotive certified), telecommunications hardware, and other electronic designs requiring efficient rectification or voltage clamping. The diode is manufactured in China under the STMicroelectronics brand and meets industry standards, though it does not carry specific approvals.

This product is new and intended for use in semiconductor electronic components manufacturing and repair. The device's small 3-pin SOT-23 layout enables integration in compact circuit boards and modules. The diode's robust electrical characteristics make it suitable for high-speed switching and power conversion.

Ideal for use in power supplies, battery protection circuits, and signal demodulation circuits. Compact, reliable, and cost-effective diode solution for electronic engineers and manufacturers.
