Overview
The BAT54SFILM is a silicon Schottky barrier diode manufactured by STMicroelectronics, housed in an SOT-23 surface-mount package. It features a series-connected, center-tapped dual-element configuration with two terminals. The device supports a maximum repetitive reverse voltage of 40 V and a continuous forward current of 300 mA per element. Key electrical parameters include a peak non-repetitive forward surge current of 1 A, a maximum forward voltage of 0.9 V, and a reverse leakage current of 1 µA at 30 V. Operating temperatures range from -40°C to +150°C junction temperature.
Feature Summary
- Utilizes Schottky barrier technology for low conduction losses and negligible switching losses.
- Features extremely fast switching speeds with low forward and reverse recovery times.
- Designed as a surface mount device with low capacitance characteristics.
Applications
- Ultra-high-speed switching circuits
- Voltage clamping applications
- Protection circuits
Procurement Notes
Verify the specific datasheet version for the BAT54SFILM to confirm pinout compatibility and exact thermal ratings. Ensure the procurement source provides official STMicroelectronics documentation to validate the component's authenticity and compliance with RoHS standards before integration into production designs.
Selection Notes
Select this component when a compact, high-speed rectification solution is required in an SOT-23 footprint. The dual-element center-tap configuration allows for efficient use in applications requiring isolated or complementary signal paths within a minimal board area constraint.
Part Context
This part belongs to the BAT54 series of general-purpose small signal Schottky diodes. The series offers various packaging options including SOD-323, SOD-523, and SOT-323, providing designers with flexibility for different surface-mount assembly requirements while maintaining consistent electrical performance profiles across the family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided reference data. Verify cross-reference compatibility with other manufacturers' dual Schottky diodes in SOT-23 packages only after confirming identical pin configurations and electrical limits.
