Overview
The Nexperia BAT721A,215 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 operates with a maximum reverse voltage of 40 V and a continuous forward current of 200 mA per diode. Key electrical characteristics include a maximum forward voltage of 550 mV at 200 mA, a peak non-repetitive forward current of 1 A, and a typical capacitance of 40 pF at 1 MHz. The junction temperature range extends from -65 °C to 125 °C.
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 package type and reel specifications. Confirm that the product status aligns with project requirements, as this variant is not automotive qualified. Check the most recent datasheet revision for any updates to limiting values or thermal characteristics before finalizing design integration.
Selection Notes
Select this component for applications requiring low forward voltage and fast switching speeds in a compact SMD footprint. Ensure the operating ambient temperature remains within the specified limits to prevent thermal runaway due to reverse power losses. Verify that the required reverse voltage does not exceed the 40 V rating under all transient conditions.
Part Context
This part belongs to the BAT721 series of Schottky barrier diodes manufactured by Nexperia. The series includes variants such as BAT721C and BAT721S, which differ in internal configuration (common cathode vs. common anode). The BAT721A specifically utilizes a common anode configuration for two diodes within the SOT23 package.

FAQ
Is the BAT721A suitable for automotive applications?
No, the BAT721A is not automotive qualified. For automotive use, Nexperia recommends using products explicitly designated with the '-Q' suffix, such as the BAT721S-QR.
What is the internal configuration of the BAT721A?
The BAT721A contains two Schottky diodes configured with a common anode. Pin 3 serves as the common anode for both diodes, while Pins 1 and 2 are the individual cathodes.
