PLVA2668A-QR

Overview

The PLVA2668A-QR is a dual common anode voltage regulator diode from the Nexperia PLVA2600A series, housed in a compact SOT-23-3 surface-mount package. It features a nominal Zener voltage of 6.8 V with a tight tolerance of ±3%. The device operates with a test current of 250 µA and exhibits a maximum reverse leakage current of 10 nA. Total power dissipation is rated at 180 mW, while non-repetitive peak reverse power dissipation reaches 30 W. The unit supports an operating temperature range from -65 °C to +150 °C and includes AEC-Q101 qualification for automotive reliability.

Feature Summary

• Dual common anode configuration integrates two regulator diodes into a single compact footprint.
• Low dynamic impedance design provides stability at low currents compared to conventional series.
• Hard breakdown knee characteristic ensures precise voltage regulation performance.
• Reduced noise profile minimizes interference in sensitive signal paths.

Applications

• General voltage regulation circuits
• Precision voltage reference functions
• Over-voltage protection stages

Procurement Notes

Verify the specific suffix 'QR' indicates the required reel packaging format during procurement. Confirm that the AEC-Q101 qualification aligns with target automotive or industrial standards. Ensure the SOT-23-3 package dimensions match the PCB layout constraints. Validate the 180 mW power dissipation rating against thermal management requirements in the final assembly.

Selection Notes

Select this component when a dual-diode solution is required within a minimal SOT-23-3 envelope. The 6.8 V nominal voltage suits applications needing stable references near standard logic levels. The low leakage current makes it suitable for high-impedance nodes. Consider the 180 mW dissipation limit for thermal planning in dense layouts.
