Overview
The BAT54S-AQ is a Schottky barrier diode array manufactured by Diotec Semiconductor, designed for high-speed switching and signal processing applications. It features two diodes connected in series within a single SOT-23 surface-mount package. The device supports a maximum repetitive reverse voltage of 30 V and an average forward rectifier current of 200 mA per diode. Key electrical characteristics include a low forward voltage of 1 V at 100 mA and a reverse leakage current of 2 µA at 25 V. It operates within a junction temperature range of -55°C to 150°C and has a reverse recovery time of 5 ns. The component is AEC-Q101 qualified for automotive reliability.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability in vehicle electronics.
- Schottky technology enables very small conduction losses and low forward voltage drop for efficient power handling.
- Compact SOT-23 surface-mount package design facilitates space-saving integration on printed circuit boards.
Applications
- Polarity protection circuits in automotive electronic systems
- Voltage clamping and signal demodulation in consumer electronics
- Blocking diodes in battery-powered devices and white goods
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the AEC-Q101 automotive grade designation matches the project requirements. Cross-reference the datasheet revision date to validate technical specifications before finalizing procurement decisions.
Selection Notes
Select this component when a dual-diode array with common cathode configuration is required in a compact footprint. The 30 V rating suits low-voltage signal processing tasks. Ensure the application demands Schottky switching speeds rather than standard PN-junction characteristics. Verify thermal management needs align with the 290 mW power dissipation limit in the target enclosure.
Part Context
This part belongs to the BAT54 family of small-signal Schottky diodes produced by Diotec Semiconductor. The 'AQ' suffix typically denotes automotive-grade qualification. The series is widely used in general-purpose electronics for its balance of speed, low loss, and small physical size compared to larger discrete diode solutions.
