BAW56T,115 Equivalent & Substitute Parts

Part Overview

The BAW56T,115 is a general-purpose diode array manufactured by NXP USA Inc., configured as a 1 Pair Common Anode device rated for 90 V DC reverse voltage and 150 mA average rectified current per diode. The component is packaged in SC-75 (SOT-416) surface mount configuration and is classified as obsolete product status.

Due to the obsolete status of BAW56T,115, equivalent substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements. Substitute parts maintain the same base product number (BAW56) and core electrical characteristics while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for BAW56T,115 is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Anode (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 90 V or higher
• Current - Average Rectified (Io) (per Diode): 150 mA or higher
• Voltage - Forward (Vf) (Max) @ If: 1.25 V or lower @ 150 mA
• Reverse Recovery Time (trr): 4 ns or lower
• Current - Reverse Leakage @ Vr: 500 nA @ 80 V or lower
• Operating Temperature - Junction (Max): 150°C or higher
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

Secondary Considerations:

• Product Status: Active status preferred due to obsolete status of main part
• Mounting Type: Surface Mount (mandatory match)
• Package compatibility: Different packages acceptable if electrical parameters are met

Substitute parts are grouped based on electrical parameter equivalence and package form factor. Parts meeting all primary criteria are classified as direct electrical equivalents, regardless of package differences.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical Equivalents (90 V / 150 mA Class):

BAW56M,315 and BAW56W,115 are complete electrical equivalents to BAW56T,115, maintaining identical voltage ratings (90 V), current ratings (150 mA), forward voltage characteristics (1.25 V @ 150 mA), reverse recovery time (4 ns), and reverse leakage current (500 nA @ 80 V). Both parts are active product status. BAW56M,315 is packaged in SOT-883 (SC-101) and carries automotive qualification (AEC-Q101). BAW56W,115 is packaged in SOT-323 (SC-70) and also carries automotive qualification (AEC-Q101). Selection between these two depends on PCB layout requirements and package footprint compatibility.

Partial Electrical Equivalents (70 V / 200 mA Class):

BAW56LT1G and BAW56TT1G both feature reduced reverse voltage rating (70 V) but increased current capacity (200 mA per diode). Both maintain identical forward voltage (1.25 V @ 150 mA) and are active product status. BAW56LT1G is packaged in SOT-23-3 (SC-59, TO-236-3) with extended operating temperature range (-55°C to 150°C). BAW56TT1G is packaged in SC-75 (SOT-416), matching the original package form factor, with extended operating temperature range (-55°C to 150°C). These parts are suitable for applications where the 70 V reverse voltage rating is sufficient and higher current capacity is beneficial.

Limited Electrical Equivalent (85 V / 75 mA Class):

BAW56T-TP features reduced current capacity (75 mA per diode) and slightly reduced reverse voltage (85 V) compared to BAW56T,115. Forward voltage is lower (1 V @ 50 mA). This part is packaged in SOT-523 and is active product status with extended operating temperature range (-55°C to 150°C). This part is suitable only for applications where current requirements do not exceed 75 mA.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original part. BAW56M,315 and BAW56W,115 carry AEC-Q101 automotive qualification, providing additional reliability assurance for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can BAW56LT1G or BAW56TT1G be used as direct replacements for BAW56T,115?

A: BAW56LT1G and BAW56TT1G are electrical equivalents with respect to diode configuration, forward voltage, and reverse recovery time. However, both feature reduced reverse voltage rating (70 V versus 90 V). These parts are suitable for applications where the circuit design operates at or below 70 V reverse voltage. If the circuit requires 90 V reverse voltage capability, these parts are not appropriate substitutes.

Q: What is the difference between BAW56M,315 and BAW56W,115?

A: Both parts are complete electrical equivalents to BAW56T,115 with identical electrical specifications (90 V, 150 mA, 1.25 V forward voltage, 4 ns recovery time). The primary difference is package form factor: BAW56M,315 uses SOT-883 (SC-101) package, while BAW56W,115 uses SOT-323 (SC-70) package. Both carry AEC-Q101 automotive qualification. Selection depends on PCB layout and available footprint space.

Q: Is BAW56T-TP suitable for all applications using BAW56T,115?

A: BAW56T-TP is not a full equivalent due to reduced current capacity (75 mA versus 150 mA per diode). This part is suitable only for applications where the maximum required current does not exceed 75 mA. For applications requiring 150 mA or higher current capacity, BAW56T-TP is not appropriate.

Q: Why do some substitute parts have extended operating temperature ranges?

A: BAW56LT1G, BAW56T-TP, and BAW56TT1G specify operating temperature range of -55°C to 150°C, while BAW56T,115, BAW56M,315, and BAW56W,115 specify maximum junction temperature of 150°C. The extended range specification indicates these parts are qualified for operation at lower temperatures. This does not affect substitution suitability for applications operating within standard temperature ranges.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (BAW56LT1G, BAW56M,315, BAW56T-TP, BAW56TT1G, and BAW56W,115) are ROHS3 compliant and carry MSL 1 (Unlimited) rating, matching the original BAW56T,115 part.

Q: What is the significance of the package differences (SC-75, SOT-23-3, SOT-883, SOT-523, SOT-323)?

A: Package differences affect PCB footprint, board space requirements, and thermal characteristics. SC-75 (SOT-416) is the original package for BAW56T,115. BAW56TT1G maintains this package form factor. Other substitutes use different packages (SOT-23-3, SOT-883, SOT-523, SOT-323) and require PCB layout verification to ensure mechanical compatibility. Electrical performance is independent of package selection among these surface mount options.

Q: Which substitute part offers the best overall compatibility with BAW56T,115?

A: BAW56TT1G offers the best overall compatibility, maintaining identical electrical specifications (90 V, 150 mA, 1.25 V forward voltage, 4 ns recovery time, 500 nA reverse leakage), the same package form factor (SC-75, SOT-416), and active product status. The only difference is extended operating temperature range (-55°C to 150°C), which provides additional capability without reducing compatibility.
