BAS28E6327HTSA1 Equivalent & Substitute Parts

Part Overview

The BAS28E6327HTSA1 is a dual independent general-purpose diode array manufactured by Infineon Technologies, rated for 80 V DC reverse voltage and 200 mA average rectified current per diode. The device is housed in a Surface Mount TO-253-4 (TO-253AA) package and features small signal switching characteristics with a 4 ns reverse recovery time.

This part carries a Last Time Buy product status, indicating that Infineon has discontinued or will discontinue production. Locating equivalent and substitute components is necessary to ensure design continuity and maintain supply chain reliability for applications currently utilizing this diode array.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS28E6327HTSA1 is determined by the following critical parameters:

Configuration Match: All substitute parts must maintain a 2 Independent diode array configuration to ensure functional equivalence in dual-diode applications.

Voltage Rating Compatibility: The main part specifies 80 V maximum DC reverse voltage. Substitute parts with equal or higher voltage ratings (75 V minimum for standard applications) are acceptable, as they provide equivalent or superior reverse voltage protection.

Current Rating Compatibility: The main part is rated for 200 mA average rectified current per diode. Substitute parts rated at 200 mA or higher current capacity are functionally compatible.

Forward Voltage Characteristics: All qualified substitutes maintain the same forward voltage specification of 1.25 V maximum at 150 mA forward current, ensuring consistent circuit performance.

Switching Speed Classification: The main part operates as a small signal diode with ≤200 mA current rating. Substitute parts classified as small signal or fast recovery devices with comparable reverse recovery times (4–6 ns range) are acceptable.

Surface Mount Technology: All substitutes must use surface mount packaging to maintain PCB assembly compatibility.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to meet environmental and moisture handling requirements.

Parameter Comparison

Engineering Selection Recommendations

BAS28,215 (NXP Semiconductors) and BAS28,235 (NXP USA Inc.)

These two parts are functionally equivalent to each other and represent the primary substitutes for the BAS28E6327HTSA1. Both maintain the same TO-253-4 (TO-253AA) package footprint, enabling direct PCB layout compatibility without redesign. The voltage rating is reduced from 80 V to 75 V, which is acceptable for applications operating below 75 V. Current capacity is increased to 215 mA, providing additional design margin. Both parts carry Active product status, ensuring long-term availability and supply chain stability. Reverse recovery time remains at 4 ns, matching the original specification. ROHS3 compliance and MSL 1 rating are maintained. These substitutes are recommended for applications where the 75 V voltage rating is sufficient and package compatibility is required.

BAS16DXV6T1G (onsemi)

This part meets all functional substitution criteria with a 75 V voltage rating, 200 mA current capacity, and 1.25 V forward voltage specification. However, the package differs from the original: BAS16DXV6T1G uses SOT-563 (SOT-666) instead of TO-253-4 (TO-253AA). This package change requires PCB layout modification and is not a direct footprint replacement. The reverse recovery time is 6 ns, slightly longer than the original 4 ns specification. Operating temperature range extends to -55°C, providing broader environmental coverage. This part carries Active product status and maintains ROHS3 compliance and MSL 1 rating. Selection of this substitute is appropriate only when PCB redesign is feasible or when the smaller SOT-563 package footprint is advantageous.

Frequently Asked Questions (FAQ)

Q: Can BAS28,215 or BAS28,235 be used as direct replacements for BAS28E6327HTSA1 without PCB modification?

A: Yes. Both NXP parts use the same TO-253-4 (TO-253AA) package as the original Infineon device, enabling direct footprint compatibility. No PCB layout changes are required for these substitutes.

Q: What is the impact of the reduced voltage rating (75 V vs. 80 V) in the NXP substitutes?

A: The 75 V rating is acceptable for applications operating at or below 75 V reverse voltage. If your circuit requires the full 80 V rating, the NXP substitutes are not suitable. Verify your application's maximum reverse voltage requirement before selection.

Q: Why does BAS16DXV6T1G have a different package (SOT-563 vs. TO-253-4)?

A: BAS16DXV6T1G is manufactured by onsemi using a different package technology. While functionally compatible, the SOT-563 package has a different footprint and requires PCB redesign. This substitute is appropriate only when layout modification is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (BAS16DXV6T1G, BAS28,215, and BAS28,235) are ROHS3 compliant with MSL 1 rating, matching the environmental and moisture handling requirements of the original BAS28E6327HTSA1.

Q: What is the difference between BAS28,215 and BAS28,235?

A: Both parts are functionally identical with the same electrical specifications, package, and performance characteristics. The difference lies in the manufacturer: BAS28,215 is supplied by NXP Semiconductors, while BAS28,235 is supplied by NXP USA Inc. Both are Active products with equivalent availability and reliability.

Q: How does the reverse recovery time difference (4 ns vs. 6 ns) affect circuit performance?

A: The BAS16DXV6T1G has a 6 ns reverse recovery time compared to the original 4 ns specification. This 2 ns difference is within the small signal diode classification and has minimal impact on most general-purpose switching applications. Verify switching frequency and circuit timing requirements if this parameter is critical to your design.

Q: What is the significance of the extended operating temperature range in BAS16DXV6T1G (-55°C to 150°C)?

A: The BAS16DXV6T1G provides a broader operating temperature range, extending to -55°C minimum. This is beneficial for applications requiring operation in cold environments. The original BAS28E6327HTSA1 and NXP substitutes specify 150°C maximum only, without a minimum temperature specification.

Q: Can I use these substitutes in high-frequency switching applications?

A: All substitute parts are classified as small signal or fast recovery diodes suitable for switching applications. The reverse recovery times (4–6 ns) are appropriate for general-purpose switching. Verify specific frequency and switching speed requirements against the datasheet specifications for your application.
