Overview
The BAT54WS (S1) is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated, housed in a SOT-323 (SC-70) package. It features a single diode configuration with a peak repetitive reverse voltage of 30 V and a maximum continuous forward current of 200 mA. The device exhibits a low forward voltage drop of 1 V at rated current and a fast peak reverse recovery time of 5 ns. Total capacitance is specified at 10 pF, supporting high-speed switching applications. The component operates within a junction temperature range up to 150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- Ultra-fast switching characteristics with negligible reverse recovery losses
- Low forward voltage drop for improved power efficiency
- PN junction protection ring for enhanced transient and ESD protection
Applications
- Automotive electronic circuits
- High-speed signal rectification
- Clamping and protection applications
Procurement Notes
Verify the manufacturer designation as Diodes Incorporated, as HY Electronic (Cayman) Limited may act as a distributor or secondary source. Confirm the specific suffix 'S1' against official datasheets to ensure it denotes the correct tape-and-reel packaging or variant without altering electrical function. Cross-reference the part number BAT54WS-7-F if standard commercial grading is required instead of automotive qualification.
Selection Notes
Select this component when a small-signal Schottky diode with low capacitance and fast recovery is needed in a compact SOT-323 footprint. It is suitable for designs requiring 30 V reverse blocking capability and 200 mA forward current handling. Consider its AEC-Q101 qualification if the application demands automotive-grade reliability and thermal stability up to 150°C junction temperature.
Part Context
The BAT54WS belongs to the BAT54 series of Schottky barrier diodes designed for surface mount technology. This series is widely used in consumer and automotive electronics due to its small form factor and efficient switching performance. The device utilizes silicon technology and is available in plastic encapsulated packages compliant with RoHS directives.
Replacement Considerations
Public confirmed substitute part numbers include BAT54SW and BAT54Y. Verify pinout compatibility and electrical ratings such as reverse voltage and forward current before substitution.
