Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter alignment with the SBAS16LT3G:

Parametric Equivalents maintain identical or equivalent electrical specifications across all critical parameters: 100 V reverse voltage, 200 mA average rectified current, 1.25 V forward voltage at 150 mA, 6 ns reverse recovery time, and 1 µA reverse leakage current at 100 V. These parts differ only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) or minor manufacturing variants within the same base product family.

Similar Parts share the same physical package (SOT-23-3) and mounting type but operate within reduced electrical parameter ranges. These parts have lower maximum reverse voltage (75 V instead of 100 V), lower average rectified current (150 mA or 300 mA), or different reverse recovery characteristics. Similar parts are suitable for applications where the reduced ratings remain within design margins.

Key parameters determining substitution eligibility:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed application requirement
• Current - Average Rectified (Io): Must equal or exceed application requirement
• Package / Case: Must be SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must encompass application operating conditions

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred for Direct Replacement)

BAS16LT1G, BAS16LT3G, and SBAS16LT1G are parametric equivalents to SBAS16LT3G with identical electrical performance. Selection among these equivalents is determined by packaging format requirements:

• SBAS16LT1G and SBAS16LT3G: Tape & Reel packaging, both carry Automotive grade and AEC-Q101 qualification, both maintain Active product status. SBAS16LT1G provides equivalent performance with higher inventory availability (71,200 pcs).

• BAS16LT1G and BAS16LT3G: Cut Tape & Digi-Reel packaging format. BAS16LT1G carries significantly higher inventory (665,100 pcs) and Active product status, suitable for applications where Tape & Reel format is not required.

Similar Part Selection (Reduced Rating Applications)

BAS16-HE3-08 (Vishay) and MMBD914-HE3-08 (Vishay) maintain 100 V reverse voltage rating but operate at reduced current (150 mA) or different forward voltage characteristics. BAS16-HE3-08 carries Last Time Buy status. Both are AEC-Q101 qualified automotive-grade devices.

MMBD4148-7-F and MMBD914-7-F (Diodes Incorporated) operate at 75 V reverse voltage with 300 mA current capacity and 4 ns reverse recovery time. These parts are Active status but lack automotive qualification. Selection is appropriate only for non-automotive applications where the 75 V rating satisfies design requirements.

Compliance and Certification Considerations

All listed parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status. Automotive applications requiring AEC-Q101 qualification must select from: SBAS16LT3G, SBAS16LT1G, BAS16-HE3-08, or MMBD914-HE3-08. Non-automotive applications may utilize any listed part provided electrical ratings are satisfied.

Frequently Asked Questions (FAQ)

Q: Can BAS16LT1G replace SBAS16LT3G in automotive applications?

A: BAS16LT1G is a parametric equivalent with identical electrical specifications and Active product status. However, BAS16LT1G does not carry automotive grade designation or AEC-Q101 qualification. For automotive applications requiring AEC-Q101 compliance, use SBAS16LT1G instead, which maintains both automotive grade and AEC-Q101 qualification while providing equivalent electrical performance.

Q: What is the difference between SBAS16LT3G and SBAS16LT1G?

A: Both parts are manufactured by onsemi with identical electrical parameters (100 V, 200 mA, 1.25 V forward voltage, 6 ns recovery time). Both carry Automotive grade and AEC-Q101 qualification. The designation difference (LT3G versus LT1G) reflects manufacturing variants. SBAS16LT1G provides higher inventory availability (71,200 pcs versus 10,300 pcs).

Q: Can MMBD914-7-F or MMBD4148-7-F be used as direct replacements?

A: These parts share the SOT-23-3 package but operate at reduced maximum reverse voltage (75 V versus 100 V) and different current ratings (300 mA versus 200 mA). Direct replacement is possible only if the application circuit operates below 75 V and the 300 mA rating does not create thermal or performance issues. These parts lack automotive qualification and are Active status only.

Q: What packaging format differences exist among equivalent parts?

A: SBAS16LT3G, SBAS16LT1G, and MMBD914-HE3-08 are supplied in Tape & Reel (TR) format, suitable for automated assembly lines requiring continuous reel feeding. BAS16LT1G, BAS16LT3G, MMBD4148-7-F, and MMBD914-7-F are supplied in Cut Tape (CT) & Digi-Reel format, suitable for lower-volume applications or manual assembly. Package selection does not affect electrical performance.

Q: Are all listed parts RoHS compliant?

A: Yes. All listed parts maintain ROHS3 compliance status. All parts carry MSL Level 1 (Unlimited moisture sensitivity level) and REACH Unaffected status, indicating no restricted substances and unlimited shelf life under standard storage conditions.

Q: Why is BAS16-HE3-08 listed as Last Time Buy?

A: BAS16-HE3-08 carries Last Time Buy product status, indicating the manufacturer has discontinued or will discontinue production. While currently available (50,200 pcs in stock), this part should not be selected for new designs. Use SBAS16LT1G or SBAS16LT3G for new applications requiring automotive-qualified equivalents.

Q: Can I use MMBD914-HE3-08 in place of SBAS16LT3G?

A: MMBD914-HE3-08 maintains 100 V reverse voltage and 200 mA current rating with AEC-Q101 automotive qualification. However, forward voltage specification differs (1 V @ 10 mA versus 1.25 V @ 150 mA), reverse leakage is higher (5 µA @ 75 V versus 1 µA @ 100 V), and reverse recovery time is faster (4 ns versus 6 ns). MMBD914-HE3-08 carries Last Time Buy status. Use SBAS16LT1G or SBAS16LT3G for new designs.

Q: What determines whether a substitute part is acceptable for my application?

A: Substitute acceptability is determined by: (1) Maximum reverse voltage rating must equal or exceed circuit maximum reverse voltage; (2) Average rectified current rating must equal or exceed circuit maximum forward current; (3) Operating temperature range must encompass application operating conditions; (4) Package and mounting type must be SOT-23-3 surface mount; (5) For automotive applications, AEC-Q101 qualification is required. Verify all parameters against circuit design specifications before selection.
