Overview
The BAT54CWFILM is a dual Schottky barrier diode from STMicroelectronics, configured as two common cathodes in an SOT-323 surface-mount package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 300 mA per diode. The device exhibits a low forward voltage drop of 900 mV at 100 mA and a peak reverse recovery time of 5 ns. Operating temperatures range from -40°C to +150°C, with a non-repetitive peak forward surge current rating of 1 A.
Feature Summary
- Dual common cathode configuration for compact circuit integration
- Low conduction losses due to minimal forward voltage drop
- Fast switching capability with negligible reverse recovery time
Applications
- General purpose signal switching applications
- High-speed digital logic circuits
- Power supply protection and clamping
Procurement Notes
Verify the specific suffix FILM against official STMicroelectronics documentation to confirm package dimensions and marking codes. Ensure compatibility with standard SOT-323 footprints during layout design. Cross-reference datasheet revisions to validate electrical characteristics and thermal performance specifications before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a small SMD package while maintaining fast switching speeds. The dual common cathode arrangement reduces board area compared to discrete single diodes. Verify that the 40 V reverse voltage rating exceeds the maximum circuit operating voltage to ensure reliable operation under all conditions.
Part Context
This part belongs to the BAT54 series of small signal Schottky diodes manufactured by STMicroelectronics. The series includes various configurations such as single, dual common cathode, and dual common anode devices. These components are designed for high-efficiency switching applications requiring low capacitance and fast response times in consumer and industrial electronics.
Replacement Considerations
BAT54CFILM: Identical electrical specifications and pinout in the same SOT-23-3 package. BAT54SWFILM: Similar performance but may differ in specific packaging or automotive qualification status. Verify exact pinout and thermal characteristics before substitution.
