BAS30LSYL Equivalent & Substitute Parts

Part Overview

The BAS30LSYL is a general-purpose rectifier diode manufactured by Nexperia USA Inc., rated for 300 V DC reverse voltage and 250 mA average rectified current. This component is packaged in a surface-mount SOD-882 (DFN1006BD-2) configuration and features fast recovery characteristics with a reverse recovery time of 50 ns. The BAS30LSYL is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering current availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS30LSYL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 300 V
• Current - Average Rectified (Io): 250 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 150 nA @ 250 V
• Capacitance @ Vr, F: 2 pF @ 0V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: SOD-882
• Supplier Device Package: DFN1006BD-2
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The BAS30LS-QYL meets all substitution criteria and is classified as an active product with current manufacturer availability.

Parameter Comparison

Engineering Selection Recommendations

The BAS30LS-QYL is the direct electrical and mechanical equivalent of the BAS30LSYL. All critical electrical parameters, including reverse voltage rating, forward voltage drop, reverse recovery time, and leakage current, are identical. Both components share the same SOD-882 package and DFN1006BD-2 supplier device package designation, ensuring pin-for-pin compatibility and identical PCB footprints.

The primary distinction between these parts is product status: the BAS30LSYL is obsolete, while the BAS30LS-QYL is active with current manufacturer availability. The BAS30LS-QYL is supplied in Tape & Reel (TR) packaging, which is standard for production environments, whereas the BAS30LSYL was available in bulk packaging.

The BAS30LS-QYL carries Automotive grade qualification and AEC-Q101 certification, indicating compliance with automotive industry reliability standards. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

For applications requiring the BAS30LSYL, the BAS30LS-QYL provides full functional and mechanical substitution with the added benefit of active product status and automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can the BAS30LS-QYL be used as a direct replacement for the BAS30LSYL in existing designs?

A: Yes. The BAS30LS-QYL is electrically and mechanically equivalent to the BAS30LSYL. All electrical parameters, including voltage ratings, current ratings, forward voltage drop, and reverse recovery time, are identical.
