SBAS20HT1G Equivalent & Substitute Parts

Part Overview

The SBAS20HT1G is a general-purpose rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 200 mA average rectified current in a surface mount SOD-323 package. This component is classified as Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or specific packaging preferences while maintaining the same functional specifications.

Substitute Part Grouping Explanation

Substitution of the SBAS20HT1G is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 200 mA minimum
Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA maximum
Reverse Recovery Time (trr): 50 ns maximum
Package / Case: SC-76, SOD-323 (surface mount)
Operating Temperature - Junction: -55°C to 150°C minimum range

Parametric Equivalent Parts meet all primary criteria with identical electrical specifications and packaging. These parts are direct functional replacements with no derating required.

Similar Parts may exceed one or more electrical parameters (higher current rating, lower reverse leakage, or enhanced temperature range) while maintaining the same package form factor. These parts are electrically compatible but represent design upgrades rather than direct equivalents. Parts with reduced voltage ratings (150 V) are not suitable for 200 V applications and are listed for reference only.

Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Replacement):

BAS20HT1G (onsemi) and BAV21WSQ-7-F (Diodes Incorporated) are parametric equivalents to SBAS20HT1G. Both parts satisfy all electrical specifications and package requirements. BAS20HT1G differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). BAV21WSQ-7-F provides identical electrical performance with Tape & Reel packaging and extended lower temperature range (-55°C to 150°C). Both parts maintain Active product status and ROHS3 compliance.

Similar Part Selection (Enhanced Performance):

BAV21WS-7-F (Diodes Incorporated) provides equivalent electrical performance with improved reverse leakage characteristics (100 nA versus 1 µA) and extended lower operating temperature (-65°C versus -55°C). This part is suitable for applications requiring enhanced temperature performance or lower leakage specifications.

BAV21WS-HE3-08 (Vishay) and BAS2103WE6327HTSA1 (Infineon) both feature 250 mA current rating, exceeding the 200 mA requirement. These parts are suitable for applications with higher current demands. BAV21WS-HE3-08 carries AEC-Q101 automotive qualification and Active status. BAS2103WE6327HTSA1 is designated Last Time Buy and should not be selected for new designs.

Parts Not Recommended for Direct Substitution:

BAV20WS-7-F and BAV20WS-AU_R1_000A1 are rated for 150 V maximum reverse voltage and are not suitable for 200 V applications. These parts are listed for reference only and do not meet the primary voltage requirement.

Frequently Asked Questions (FAQ)

Q: Can BAS20HT1G replace SBAS20HT1G in all applications?

A: Yes. BAS20HT1G is a parametric equivalent with identical electrical specifications (200 V, 200 mA, 1.25 V forward voltage, 50 ns recovery time) and SOD-323 package. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both parts are onsemi products with Active status and ROHS3 compliance.

Q: What is the difference between parametric equivalents and similar parts?

A: Parametric equivalents meet all electrical and mechanical specifications identically. Similar parts exceed one or more electrical parameters (such as current rating or reverse leakage) while maintaining package compatibility. Similar parts are electrically compatible but represent design upgrades rather than direct replacements.

Q: Why are BAV20WS-7-F and BAV20WS-AU_R1_000A1 listed if they cannot replace SBAS20HT1G?

A: These parts are listed in the provided substitute data but are not suitable for direct substitution due to reduced voltage rating (150 V maximum versus 200 V required). They are included for reference to clarify substitution boundaries and prevent incorrect part selection.

Q: Can BAV21WS-HE3-08 or BAS2103WE6327HTSA1 be used instead of SBAS20HT1G?

A: Both parts meet the 200 V and 200 mA requirements with enhanced 250 mA current ratings. BAV21WS-HE3-08 is suitable for new designs with Active product status and AEC-Q101 qualification. BAS2103WE6327HTSA1 carries Last Time Buy status and should not be selected for new designs.

Q: What packaging options are available for equivalent parts?

A: SBAS20HT1G is supplied in Tape & Reel (TR) format. BAS20HT1G is available in Cut Tape (CT) & Digi-Reel® format. BAV21WSQ-7-F is available in Tape & Reel (TR) format. BAV21WS-7-F is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly equipment and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status. All parts also maintain Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 qualification indicates the part meets automotive industry reliability standards. SBAS20HT1G carries this qualification. BAV21WS-HE3-08 also carries AEC-Q101 qualification, making it suitable for automotive applications. Other substitute parts do not carry this qualification but remain suitable for general industrial applications.
