Overview
The BAT54SWFILM is a dual Schottky barrier diode array manufactured by STMicroelectronics, housed in an SOD-523 surface-mount package. It features two series-connected elements with a center tap configuration. The device supports a maximum repetitive reverse voltage of 40V and an average forward rectified current of 300mA per diode. Key electrical characteristics include a maximum forward voltage of 900mV at 100mA and a peak reverse recovery time of 5ns. It operates within a junction temperature range of -40°C to +150°C.
Feature Summary
- Dual Schottky barrier diodes configured as series-connected elements with a center tap for efficient signal processing.
- Extremely fast switching capabilities with negligible reverse recovery time suitable for high-frequency applications.
- Low conduction and reverse losses combined with low forward voltage drop for improved energy efficiency.
Applications
- Automotive small signal rectification circuits
- High-speed switching power supplies
- Signal demodulation and detection
Procurement Notes
Verify the specific suffix FILM against official STMicroelectronics documentation to confirm the SOD-523 packaging and pinout configuration. Ensure compliance with RoHS directives and check for automotive qualification status if required for your specific application environment. Cross-reference datasheets for thermal management requirements during operation.
Selection Notes
Select this component when a compact dual Schottky diode solution with a center tap is required for space-constrained designs. The SOD-523 package offers a small footprint compared to traditional SOT-23 options. Consider the 40V rating and 300mA current capacity to ensure adequate headroom for your circuit's peak operating conditions.
Part Context
This part belongs to the BAT54 series of general-purpose small signal Schottky diodes from STMicroelectronics. The series includes various configurations such as common cathode and common anode arrangements in packages like SOT-23 and SOT-323. The BAT54SWFILM specifically denotes the series-connected dual variant in the smaller SOD-523 form factor.
