BAW56UE6433HTMA1 Equivalent & Substitute Parts

Part Overview

The BAW56UE6433HTMA1 is a general-purpose diode array manufactured by Infineon Technologies, configured as a 2 Pair Common Anode device rated for 80 V DC reverse voltage and 200 mA average rectified current per diode. The component is housed in a Surface Mount SC-74 (SOT-457) package and is supplied in Tape & Reel format.

This part carries a "Not For New Designs" product status, indicating that Infineon has discontinued active development and support for this specific model variant. Equivalent and substitute parts are necessary to ensure design continuity, maintain supply chain reliability, and support existing production requirements where the original part is no longer readily available or where design flexibility permits component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAW56UE6433HTMA1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 2 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 80 V
• Technology: Standard
• Speed Classification: Small Signal ≤ 200 mA (Io), Any Speed
• Reverse Recovery Time (trr): 4 ns
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Flexible Parameters (Allowable Variation):

• Current - Average Rectified (Io) (per Diode): Equal or greater than 200 mA
• Voltage - Forward (Vf) (Max) @ If: Equal or lower than 1.25 V @ 150 mA
• Current - Reverse Leakage @ Vr: Equal or lower than 150 nA @ 70 V
• Operating Temperature - Junction (Max): Equal or greater than 150°C
• Package / Case: SC-74, SOT-457 or equivalent surface mount packages with identical pinout and footprint

Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (Infineon Technologies) and manufacturer-recommended alternatives from other suppliers (onsemi). All substitutes maintain the core electrical and mechanical specifications required for direct component replacement within the specified application constraints.

Parameter Comparison

Engineering Selection Recommendations

BAW56UE6327HTSA1 (Parametric Equivalent - Infineon Technologies)

The BAW56UE6327HTSA1 is a parametric equivalent to the BAW56UE6433HTMA1, offering identical electrical specifications and package configuration. Both devices maintain the same 80 V reverse voltage rating, 200 mA average rectified current per diode, and SC-74 (SOT-457) surface mount package. The BAW56UE6327HTSA1 carries an Obsolete product status, indicating end-of-life classification. Both parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating. This substitute is suitable for applications requiring direct pin-for-pin and footprint-compatible replacement without design modification.

NSDEMP11XV6T5G (Manufacturer-Recommended Alternative - onsemi)

The NSDEMP11XV6T5G is a manufacturer-recommended substitute from onsemi, maintaining the same 80 V reverse voltage rating, 2 Pair Common Anode configuration, and 4 ns reverse recovery time. This device differs in current rating (100 mA per diode versus 200 mA) and package format (SOT-563, SOT-666 versus SC-74, SOT-457). The NSDEMP11XV6T5G exhibits lower forward voltage (1.2 V @ 100 mA) and lower reverse leakage current (100 nA @ 70 V). This substitute is applicable only in applications where the reduced current rating of 100 mA per diode is acceptable and where PCB layout can accommodate the different SOT-563/SOT-666 package footprint. The part carries Obsolete product status and is ROHS3 Compliant with MSL 1 (Unlimited) rating.

Both substitutes are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8541.10.0070, matching the regulatory classification of the main part.

Frequently Asked Questions (FAQ)

Q: Can BAW56UE6327HTSA1 be used as a direct replacement for BAW56UE6433HTMA1?

A: Yes. The BAW56UE6327HTSA1 is a parametric equivalent with identical electrical specifications and package configuration. Both devices are housed in SC-74 (SOT-457) surface mount packages with matching pinouts and footprints, enabling direct pin-for-pin substitution without circuit design modification.

Q: What is the primary difference between BAW56UE6433HTMA1 and NSDEMP11XV6T5G?

A: The primary differences are current rating and package format. The BAW56UE6433HTMA1 is rated for 200 mA average rectified current per diode in an SC-74 (SOT-457) package, while the NSDEMP11XV6T5G is rated for 100 mA per diode in a SOT-563 (SOT-666) package. The NSDEMP11XV6T5G exhibits lower forward voltage and reverse leakage current characteristics. Substitution requires verification that the application current requirements do not exceed 100 mA per diode and that the PCB layout can accommodate the different package footprint.

Q: Are all three parts ROHS3 compliant?

A: Yes. The BAW56UE6433HTMA1, BAW56UE6327HTSA1, and NSDEMP11XV6T5G are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). All three parts are REACH Unaffected and carry the same ECCN (EAR99) and HTSUS (8541.10.0070) classifications.

Q: What does "Not For New Designs" status mean for BAW56UE6433HTMA1?

A: "Not For New Designs" indicates that Infineon has discontinued active development and support for this specific part variant. While existing inventory remains available, the manufacturer does not recommend this part for new circuit designs. For new designs, equivalent parts such as BAW56UE6327HTSA1 or NSDEMP11XV6T5G should be evaluated.

Q: Can NSDEMP11XV6T5G be used in applications requiring 200 mA per diode?

A: No. The NSDEMP11XV6T5G is rated for a maximum of 100 mA average rectified current per diode. Applications requiring 200 mA per diode must use BAW56UE6433HTMA1 or BAW56UE6327HTSA1, both of which are rated for 200 mA per diode.

Q: What is the difference in package footprint between SC-74 (SOT-457) and SOT-563 (SOT-666)?

A: SC-74 (SOT-457) and SOT-563 (SOT-666) are distinct surface mount package formats with different physical dimensions and pinout configurations. Direct footprint compatibility is not guaranteed. PCB layout modification is required if substituting NSDEMP11XV6T5G (SOT-563/SOT-666) for BAW56UE6433HTMA1 (SC-74/SOT-457).

Q: Are there any temperature operating range differences between the substitutes?

A: The BAW56UE6433HTMA1 and BAW56UE6327HTSA1 specify a maximum junction temperature of 150°C. The NSDEMP11XV6T5G specifies an operating temperature range of -55°C to 150°C, providing explicit minimum temperature specification. All three parts support the same maximum junction temperature of 150°C.
