Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV103-IR08 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 250 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: DO-213AC, MINI-MELF, SOD-80
• Mounting Type: Surface Mount

Compliance Parameters (Must Match or Exceed):

• Operating Temperature - Junction (Max): 175°C
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts may differ in packaging format (Cut Tape, Tape & Reel, or bulk) and forward voltage characteristics within acceptable operating ranges. All identified substitutes maintain identical electrical performance and mechanical compatibility with the BAV103-IR08.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Vishay BAV103-GS08 and BAV103-GS18):

The BAV103-GS08 and BAV103-GS18 are parametric equivalents of the BAV103-IR08, maintaining identical electrical specifications and mechanical compatibility. Both parts are manufactured by Vishay General Semiconductor and carry active product status. The BAV103-GS08 is supplied in Cut Tape and Digi-Reel packaging formats, while the BAV103-GS18 is supplied in Tape & Reel format. Both maintain automotive grade classification, AEC-Q101 qualification, ROHS3 compliance, and MSL 1 rating. Selection between these two should be based on packaging and supply chain requirements.

Manufacturer Recommended Equivalent (NXP BAV103,115):

The NXP BAV103,115 is designated as a manufacturer-recommended equivalent. This part maintains the same reverse voltage (200 V), average rectified current (250 mA), reverse recovery time (50 ns), and reverse leakage current specifications. The forward voltage specification differs at 1.25 V @ 200 mA compared to 1 V @ 100 mA for the Vishay variants, representing a higher forward voltage drop under higher current conditions. The NXP part is supplied in LLDS MiniMelf packaging and demonstrates significantly higher inventory availability. Automotive grade and AEC-Q101 qualification status are not specified for the NXP part in the provided data.

Selection Criteria:

For applications requiring confirmed automotive qualification and AEC-Q101 certification, the Vishay BAV103-GS08 or BAV103-GS18 are the appropriate selections. For applications where forward voltage drop at elevated current is a design constraint, the Vishay variants with lower forward voltage specification are preferred. For high-volume applications prioritizing supply availability, the NXP BAV103,115 offers substantially higher inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the BAV103-IR08 be directly replaced with BAV103-GS08 or BAV103-GS18?

A: Yes. The BAV103-GS08 and BAV103-GS18 are parametric equivalents with identical electrical specifications and mechanical compatibility. Both maintain the same 200 V reverse voltage rating, 250 mA average rectified current, 50 ns reverse recovery time, and SOD-80 MiniMELF package. The primary difference is packaging format: BAV103-GS08 is supplied in Cut Tape and Digi-Reel, while BAV103-GS18 is supplied in Tape & Reel.

Q: What is the difference between the Vishay and NXP substitutes?

A: The Vishay BAV103-GS08 and BAV103-GS18 maintain identical forward voltage specifications (1 V @ 100 mA) to the BAV103-IR08. The NXP BAV103,115 specifies forward voltage at 1.25 V @ 200 mA, indicating higher forward voltage drop under higher current conditions. All three parts maintain identical reverse voltage, current rating, and recovery time specifications. The Vishay parts carry explicit automotive grade and AEC-Q101 qualification designations; the NXP part does not specify these in the provided data.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All substitute parts use the DO-213AC, MINI-MELF, SOD-80 package with surface mount mounting type. PCB footprints and assembly processes remain unchanged. Packaging format differences (Cut Tape, Tape & Reel, or bulk) affect supply chain and handling but not component compatibility.

Q: Which substitute should be selected for automotive applications?

A: For applications requiring documented automotive qualification, the Vishay BAV103-GS08 or BAV103-GS18 are specified with automotive grade classification and AEC-Q101 qualification. The NXP BAV103,115 does not specify automotive grade or AEC-Q101 qualification in the provided data.

Q: Does forward voltage difference affect circuit performance?

A: Forward voltage differences between substitutes may affect circuit performance in applications where forward voltage drop is a design constraint. The Vishay variants specify 1 V @ 100 mA, while the NXP variant specifies 1.25 V @ 200 mA. Circuit designs should verify that forward voltage specifications of selected substitutes remain within acceptable operating parameters.

Q: What is the significance of the obsolete status of BAV103-IR08?

A: The BAV103-IR08 is classified as obsolete, indicating that Vishay General Semiconductor no longer manufactures this specific part variant. Active equivalent alternatives (BAV103-GS08, BAV103-GS18, and NXP BAV103,115) are available for new designs and ongoing production. Existing inventory of BAV103-IR08 is limited to 766 pieces.

Q: Are all substitutes RoHS3 compliant?

A: The Vishay BAV103-GS08 and BAV103-GS18 are explicitly specified as ROHS3 compliant. RoHS compliance status is not specified for the NXP BAV103,115 in the provided data.
