Overview
The Nexperia BAT721A,235 is a planar Schottky barrier dual diode featuring an integrated guard ring for stress protection. It is encapsulated in a SOT23 (TO-236AB) small Surface-Mounted Device plastic package with three terminals. The device supports a maximum forward current of 200 mA per diode and a reverse voltage rating of 40 V. Key electrical characteristics include a maximum forward voltage of 550 mV at 200 mA, a typical capacitance of 40 pF at 1 MHz, and a non-repetitive peak forward current capability of 1 A.
Feature Summary
- Low forward voltage operation
- Low capacitance performance
- Integrated guard ring for stress protection
Applications
- Ultra high-speed switching
- Line termination
- Voltage clamping
- Reverse polarity protection
Procurement Notes
Verify the specific ordering suffix to confirm packaging details, as the provided datasheet references the standard SOT23 package without specifying reel or cut tape quantities. Confirm that the product status aligns with project requirements, noting that this specific part number is not automotive qualified according to the revision history. Ensure compatibility with standard surface-mount assembly processes by referencing the provided soldering footprint dimensions.
Selection Notes
Select this component for designs requiring a compact dual Schottky configuration in a SOT23 package. The low forward voltage and capacitance make it suitable for high-frequency applications. Note that this version lacks automotive qualification; if AEC-Q101 compliance is required, consider alternative Nexperia series variants explicitly designated for automotive use. Verify thermal management needs against the junction-to-ambient resistance specifications.
Part Context
This component belongs to the BAT721 series of Schottky barrier diodes manufactured by Nexperia. The series includes various configurations such as single, common anode, and common cathode arrangements in packages like SOD323 and SOT23. The BAT721A specifically denotes the common anode dual diode configuration within this family, designed for general-purpose high-speed switching and signal processing tasks.

FAQ
Is the BAT721A,235 automotive qualified?
No, the revision history indicates that this product data sheet supersedes previous versions and explicitly states the product is not automotive qualified. Automotive-grade alternatives are available separately.
What is the internal configuration of the BAT721A?
The BAT721A contains two Schottky diodes connected in a common anode configuration, where pins 1 and 2 serve as individual cathodes and pin 3 serves as the common anode.
What is the maximum operating junction temperature?
The maximum junction temperature (Tj) is limited to 125 °C according to the limiting values section of the datasheet.
