BAS16TT1G Equivalent & Substitute Parts

Part Overview

The BAS16TT1G is a general-purpose rectifier diode manufactured by onsemi, rated for 100 V DC reverse voltage and 200 mA average rectified current. The device is packaged in SC-75 (SOT-416) surface mount configuration and is classified as a small signal diode with standard recovery characteristics. This part is active in production status and RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, accounting for packaging variations and manufacturing source alternatives. Substitution becomes necessary when the primary part experiences supply constraints, lead time extensions, or when design requirements permit alternative package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS16TT1G are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 200 mA minimum
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA maximum
• Mounting Type: Surface Mount
• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Grouping Logic:

Group A - Full Electrical Equivalents (100 V, ≥200 mA): Parts BAS16,215 and BAS16,235 meet or exceed all primary electrical parameters with improved reverse recovery time (4 ns vs. 6 ns) and lower reverse leakage current (500 nA vs. 1 µA). These parts are qualified to AEC-Q101 automotive standard and feature fast recovery characteristics. Package variants (TO-236AB) differ from the main part but maintain surface mount compatibility.

Group B - Reduced Current Rating (85 V, 75 mA): Part BAS16T-7-F operates at reduced voltage and current ratings (85 V, 75 mA) and is suitable only for applications where the design specifications permit lower electrical ratings. This part is not a direct substitute for designs requiring full 100 V / 200 mA performance.

Group C - Compact Package Alternative (100 V, ≥200 mA): Part BAS16L,315 maintains full electrical equivalence with a miniaturized DFN1006-2 package (SOD-882), offering space-constrained design alternatives while preserving electrical performance and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence (100 V, 200+ mA):

Parts BAS16,215 and BAS16,235 provide full electrical substitution with enhanced performance characteristics. Both parts exceed the minimum current rating (215 mA vs. 200 mA) and feature improved reverse recovery time (4 ns vs. 6 ns) and reduced reverse leakage current. BAS16,215 and BAS16,235 are both RoHS3 compliant with MSL 1 rating. BAS16,215 and BAS16,235 are qualified to AEC-Q101 automotive standard, suitable for automotive and industrial applications requiring enhanced reliability.

For Space-Constrained Designs:

Part BAS16L,315 maintains full electrical equivalence while offering a miniaturized DFN1006-2 package (SOD-882). This part is qualified to AEC-Q101 and provides identical electrical performance to the main part with reduced footprint. Package selection depends on PCB layout requirements and assembly equipment compatibility.

For Reduced Rating Applications:

Part BAS16T-7-F operates at 85 V / 75 mA and is suitable only for applications where design specifications permit lower voltage and current ratings. This part is not recommended as a substitute for designs requiring the full 100 V / 200 mA performance envelope.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. Automotive-qualified alternatives (BAS16,215, BAS16L,315) provide additional qualification documentation for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can BAS16,215 or BAS16,235 be used as direct replacements for BAS16TT1G?

A: Yes. Both parts meet or exceed the electrical specifications of the BAS16TT1G, including 100 V reverse voltage rating and 215 mA current rating (exceeding the 200 mA requirement). Forward voltage, reverse recovery time, and leakage current specifications are compatible. Package differences (TO-236AB vs. SC-75) require PCB layout verification for pin compatibility and thermal performance.

Q: What is the primary difference between BAS16,215 and BAS16,235?

A: Both parts are electrically identical with identical electrical parameters. The primary difference is packaging format: BAS16,215 is supplied in Cut Tape (CT) & Digi-Reel® format, while BAS16,235 is supplied in Bulk packaging. Manufacturer source differs (Nexperia USA Inc. vs. NXP Semiconductors), but both are RoHS3 compliant and meet the same electrical specifications.

Q: Is BAS16L,315 suitable for the same applications as BAS16TT1G?

A: Yes, for applications where the DFN1006-2 (SOD-882) package is compatible with the PCB design. BAS16L,315 provides identical electrical performance with a smaller footprint. AEC-Q101 automotive qualification is included. Package selection depends on available PCB space and assembly equipment capability.

Q: Can BAS16T-7-F replace BAS16TT1G in all applications?

A: No. BAS16T-7-F operates at reduced ratings (85 V / 75 mA) and is not suitable for applications requiring the full 100 V / 200 mA performance. This part is only applicable to designs with lower voltage and current requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (BAS16,215, BAS16,235, BAS16L,315, BAS16T-7-F) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the main part.

Q: What is the significance of AEC-Q101 qualification on BAS16,215 and BAS16L,315?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts bearing this qualification have undergone enhanced reliability testing and are approved for automotive applications. This qualification is optional for general industrial use but provides additional assurance for regulated or mission-critical applications.

Q: How do reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and switching losses. BAS16TT1G has 6 ns trr, while substitute parts BAS16,215, BAS16,235, and BAS16L,315 have 4 ns trr. The faster recovery time in substitutes reduces switching losses and improves high-frequency performance. For applications operating below 1 MHz, this difference is negligible. For high-frequency switching applications, the improved trr of substitute parts provides performance benefits.

Q: What packaging considerations apply when substituting BAS16TT1G with alternative parts?

A: BAS16TT1G uses SC-75 (SOT-416) package. Substitute parts use different packages: BAS16,215 and BAS16,235 use TO-236AB (SOT-23-3), BAS16L,315 uses DFN1006-2 (SOD-882), and BAS16T-7-F uses SOT-523. Each package has different pin configurations, footprints, and thermal characteristics. PCB layout redesign and assembly equipment verification are required when changing packages.
