BAW156-QR

Diode Arrays Overview

The BAW156-QR is a low-leakage double diode manufactured by Nexperia. It features an epitaxial medium-speed switching design housed in a small SOT23 (TO-236AB) plastic surface-mount package. The device utilizes a common anode configuration for the dual diodes. Key electrical characteristics include a maximum continuous reverse voltage of 75 V and a repetitive peak reverse voltage of 85 V. The component supports a repetitive peak forward current of up to 500 mA. It is qualified to the AEC-Q101 standard, ensuring suitability for automotive applications requiring high reliability.

Diode Arrays Feature Summary

• Low leakage current performance with typical values around 3 pA
• Medium-speed switching capability with a typical switching time of 0.8 µs
• Automotive grade qualification compliant with AEC-Q101 standards
• Common anode configuration within a compact SOT23 surface-mount package

Diode Arrays Applications

• Low-leakage current applications in surface-mounted circuits
• Automotive electronic systems requiring AEC-Q101 qualified components
• Signal processing circuits demanding minimal reverse bias current

Diode Arrays Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm packaging details and tape-and-reel specifications. Ensure the selected variant meets the required automotive quality standards and temperature ratings defined in the datasheet. Cross-reference the ordering part number with authorized distributors to guarantee authenticity and traceability for production use.

Diode Arrays Selection Notes

Select this component when designing circuits that require dual diodes with exceptionally low reverse leakage currents. The common anode topology simplifies layout compared to discrete single diodes. Consider the SOT23 package size for space-constrained designs. Verify that the 75 V reverse voltage rating aligns with the circuit's operating conditions and transient requirements.

Diode Arrays Part Context

This component belongs to Nexperia's portfolio of small signal switching diodes. It is part of the BAW series, which focuses on low-leakage performance. The BAW156-QR shares the same internal die and electrical characteristics as the standard BAW156, differing primarily in packaging and automotive qualification status. It serves as a specialized solution for sensitive analog and digital interfaces.

Diode Arrays Replacement Considerations

The standard BAW156 is the primary equivalent part number. Verify if the non-automotive version satisfies the application's reliability requirements. Other low-leakage dual diodes from different manufacturers may require pinout and electrical parameter validation before substitution.
