Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS28E6433HTMA1 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Diode configuration must remain 2 Independent
• Voltage - DC Reverse (Vr) must equal or exceed 80 V
• Current - Average Rectified (Io) per diode must equal or exceed 200 mA
• Voltage - Forward (Vf) must be compatible at rated current
• Reverse Recovery Time (trr) must support the intended switching application
• Reverse Leakage Current must remain within acceptable limits

Mechanical Compatibility Criteria:

• Mounting type must be Surface Mount
• Package / Case must be compatible with PCB layout and assembly equipment
• Supplier Device Package designation must support the same footprint or allow rework

Compliance & Environmental Criteria:

• RoHS3 Compliance required
• Moisture Sensitivity Level (MSL) must be acceptable for storage and assembly processes

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical and mechanical specifications with different packaging) and Manufacturer Recommended Alternatives (functionally compatible with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

BAS28E6327HTSA1 (Parametric Equivalent - Infineon Technologies)

This part is a direct parametric equivalent to the BAS28E6433HTMA1, with identical electrical specifications and package designation. The only difference is packaging format: BAS28E6327HTSA1 is supplied in Cut Tape (CT) format with higher inventory availability (2550 pcs) compared to the main part's Tape & Reel (TR) format. Both parts carry Last Time Buy status from Infineon. This substitute is suitable for applications where packaging format does not impose assembly constraints. RoHS3 compliance and MSL 1 rating are maintained.

BAS16DXV6T1G (onsemi - Alternative Package)

The BAS16DXV6T1G is an active product from onsemi with the highest inventory availability (10400 pcs). It meets the core electrical requirements: 2 Independent diode configuration, 200 mA per diode, and 1.25 V forward voltage. However, three parameter deviations exist: (1) Voltage - DC Reverse is reduced to 75 V (5 V lower than the main part), (2) Reverse Recovery Time is 6 ns (2 ns slower), and (3) Reverse Leakage Current is 1 µA (10× higher). The package is SOT-563 (SOT-666), which differs from the TO-253-4 footprint and requires PCB layout modification. This substitute is applicable only when the 75 V reverse voltage rating and increased leakage current are acceptable for the application. Operating temperature range is expanded to -55°C ~ 150°C.

BAS28,215 (NXP Semiconductors - Active Product)

The BAS28,215 is an active product with substantial inventory (800509 pcs). Electrical specifications are compatible with minor enhancements: 75 V reverse voltage (5 V lower), 215 mA per diode (15 mA higher), and 4 ns reverse recovery time (matching the main part). The package remains TO-253-4 (TO-253AA), eliminating layout rework. Reverse Leakage Current is 1 µA (10× higher than the main part). Speed classification is Fast Recovery (≤500ns, >200mA), compared to Small Signal for the main part. This substitute maintains mechanical compatibility and is suitable when the reduced reverse voltage and increased leakage are acceptable.

BAS28,235 (NXP USA Inc. - Active Product)

The BAS28,235 is functionally identical to BAS28,215, supplied by NXP USA Inc. with comparable inventory (747532 pcs). All electrical and mechanical parameters match BAS28,215. RoHS3 compliance and ECCN/HTSUS classifications are specified. This substitute offers the same compatibility profile as BAS28,215 with alternative supplier sourcing.

Selection Priority:

For direct replacement without design modification: BAS28E6327HTSA1 (identical specifications, packaging format difference only).

For active product with maintained package compatibility: BAS28,215 or BAS28,235 (NXP alternatives with enhanced current rating and active product status).

For alternative package with highest availability: BAS16DXV6T1G (requires PCB layout modification and acceptance of reduced reverse voltage and increased leakage).

Frequently Asked Questions (FAQ)

Q: Can BAS28E6327HTSA1 be used as a direct replacement for BAS28E6433HTMA1?

A: Yes. BAS28E6327HTSA1 is a parametric equivalent with identical electrical specifications (80 V, 200 mA, 4 ns trr) and the same package designation (TO-253-4, TO-253AA). The difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). Both are Last Time Buy products from Infineon. Assembly equipment compatibility depends on whether the production line accepts both tape formats.

Q: What are the consequences of using BAS16DXV6T1G instead of BAS28E6433HTMA1?

A: Three electrical parameters change: (1) Reverse voltage decreases from 80 V to 75 V, reducing overvoltage margin by 5 V; (2) Reverse Recovery Time increases from 4 ns to 6 ns, affecting switching speed; (3) Reverse Leakage Current increases from 100 nA to 1 µA at 75 V, increasing power dissipation. The package changes from TO-253-4 to SOT-563, requiring PCB layout modification. Use this substitute only when the application specifications accommodate these parameter changes.

Q: Are BAS28,215 and BAS28,235 interchangeable?

A: Yes. Both parts are functionally identical with the same electrical specifications, package, and performance characteristics. The difference is manufacturer: BAS28,215 is supplied by NXP Semiconductors, and BAS28,235 is supplied by NXP USA Inc. Both are active products with substantial inventory. Selection between them depends on supplier availability and procurement agreements.

Q: What is the significance of the 75 V reverse voltage in NXP alternatives compared to the 80 V rating of the main part?

A: The 5 V difference represents a reduction in maximum reverse voltage rating. In applications where the reverse voltage approaches or exceeds 75 V, the NXP alternatives (BAS28,215 and BAS28,235) may not provide adequate safety margin. Verify that the application's maximum reverse voltage does not exceed 75 V before substitution.

Q: Does the increased reverse leakage current in substitute parts affect circuit performance?

A: The reverse leakage current increases from 100 nA to 1 µA in BAS16DXV6T1G, BAS28,215, and BAS28,235. This 10× increase may affect circuits sensitive to leakage current, such as precision analog circuits, high-impedance signal paths, or low-power applications. Evaluate the application's leakage current tolerance before substitution.

Q: Can BAS28E6433HTMA1 be replaced with BAS16DXV6T1G without PCB modification?

A: No. BAS16DXV6T1G uses SOT-563 package, while BAS28E6433HTMA1 uses TO-253-4 (TO-253AA). The footprints are incompatible. PCB layout modification is required, including pad repositioning and trace routing changes. This substitution is not suitable for existing designs without hardware revision.

Q: What is the product status significance for long-term supply planning?

A: BAS28E6433HTMA1 and BAS28E6327HTSA1 carry Last Time Buy status, indicating Infineon will discontinue production. BAS16DXV6T1G, BAS28,215, and BAS28,235 are Active products with ongoing production and supply availability. For new designs or long-term production, Active products are recommended to ensure sustained component availability.

Q: Are all substitute parts RoHS3 compliant?

A: BAS28E6433HTMA1, BAS28E6327HTSA1, BAS16DXV6T1G, and BAS28,235 are explicitly specified as ROHS3 Compliant. BAS28,215 does not specify RoHS status in the provided data. Verify RoHS compliance with the supplier before procurement if regulatory compliance is required.
