BAT721A-QR

Overview

The Nexperia BAT721A-Q is a planar Schottky barrier dual diode with an integrated guard ring for stress protection, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted Device plastic package. It features a maximum forward current of 200 mA per diode and a reverse voltage rating of 40 V. The typical forward voltage is 550 mV at 200 mA, while the reverse current is 15 µA at 25 °C. The device operates within a junction temperature range up to 125 °C and an ambient temperature range from -65 °C to 150 °C.

Feature Summary

Low forward voltage
Low capacitance
Qualified according to AEC-Q101 and recommended for use in automotive applications

Applications

Ultra high-speed switching
Line termination
Voltage clamping
Reverse polarity protection

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity or cut-tape format. Confirm that the AEC-Q101 qualification status aligns with the target automotive application requirements. Ensure the SOT23 footprint dimensions match the PCB design guidelines provided in the datasheet package outline section.

Selection Notes

Select this component when low forward voltage and low capacitance are critical for high-speed signal integrity. The dual common-anode configuration allows for efficient reverse polarity protection circuits. Verify thermal resistance limits under free-air conditions versus mounted on FR4 PCBs to ensure safe operating junction temperatures during peak load scenarios.

Part Context

This part belongs to the BAT721 series of Schottky barrier diodes manufactured by Nexperia. The series includes variants such as BAT721, BAT721C, and BAT721S, differing primarily in internal configuration like single, dual common cathode, or dual common anode setups. All share similar electrical characteristics and packaging constraints.
