BAV101-GS18 Equivalent & Substitute Parts

Part Overview

The BAV101-GS18 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 100 V DC reverse voltage with 250 mA average rectified current and features fast recovery characteristics with a 50 ns reverse recovery time. The device is housed in a SOD-80 MiniMELF package and carries automotive-grade qualification under AEC-Q101. The BAV101-GS18 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV101-GS18 are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, reverse leakage current, and package form factor. These parts are directly interchangeable without circuit redesign.

Manufacturer Recommended Alternatives may exhibit variations in secondary parameters such as reverse recovery time classification, capacitance, or reverse leakage current while maintaining compatibility with the primary application requirements. These parts are suitable for applications where the specified parameter variations do not impact circuit performance.

The following key parameters determine substitution eligibility:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 100 V
• Current - Average Rectified (Io): Must equal or exceed 250 mA
• Package / Case: Must be DO-213AC, MINI-MELF, or SOD-80
• Mounting Type: Must be Surface Mount
• Operating Temperature - Junction (Max): Must equal or exceed 175°C

Parameter Comparison

Engineering Selection Recommendations

BAV101-GS08 is a parametric equivalent to the BAV101-GS18. Both devices are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications across all critical parameters including reverse voltage, average rectified current, forward voltage drop, reverse recovery time, and reverse leakage current. Both components carry automotive-grade qualification under AEC-Q101 and are ROHS3 compliant. The BAV101-GS08 is suitable for direct substitution in applications currently specified for the BAV101-GS18 without circuit modification.

BAS45AL,115 is a manufacturer-recommended alternative manufactured by Nexperia USA Inc. This device maintains the same reverse voltage rating of 125 V (exceeding the 100 V requirement), identical average rectified current of 250 mA, and matching forward voltage drop of 1 V @ 100 mA. The BAS45AL,115 differs in speed classification, operating as a standard recovery diode with a reverse recovery time of 1.5 µs compared to the 50 ns fast recovery specification of the BAV101-GS18. The BAS45AL,115 does not carry automotive-grade qualification or AEC-Q101 certification. Selection of this alternative is appropriate for non-automotive applications or where standard recovery characteristics are acceptable. Both the BAV101-GS08 and BAS45AL,115 are housed in compatible SOD-80 MiniMELF packages and support surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can BAV101-GS08 be used as a direct replacement for BAV101-GS18?

A: Yes. The BAV101-GS08 is a parametric equivalent with identical electrical specifications and package form factor. Both devices are manufactured by Vishay General Semiconductor - Diodes Division, carry AEC-Q101 automotive qualification, and are ROHS3 compliant. No circuit redesign is required.

Q: What is the primary difference between BAV101-GS18 and BAS45AL,115?

A: The primary difference is the reverse recovery time classification. The BAV101-GS18 is a fast recovery diode with 50 ns reverse recovery time, while the BAS45AL,115 is a standard recovery diode with 1.5 µs reverse recovery time. Additionally, the BAS45AL,115 does not carry automotive-grade qualification or AEC-Q101 certification. The BAS45AL,115 provides a higher reverse voltage rating of 125 V versus 100 V.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SOD-80 MiniMELF package form factor (DO-213AC, MINI-MELF, SOD-80) and are surface mount devices. PCB footprints are compatible across all three components.

Q: Is the BAS45AL,115 suitable for automotive applications?

A: The BAS45AL,115 does not carry automotive-grade qualification or AEC-Q101 certification. For automotive applications requiring these qualifications, the BAV101-GS18 or BAV101-GS08 are the appropriate selections.

Q: What does the reverse recovery time difference mean for circuit performance?

A: Reverse recovery time affects switching speed and efficiency in high-frequency applications. The BAV101-GS18 and BAV101-GS08 with 50 ns recovery time are suitable for fast-switching circuits. The BAS45AL,115 with 1.5 µs recovery time is appropriate for lower-frequency applications where fast switching is not required.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts—BAV101-GS18, BAV101-GS08, and BAS45AL,115—are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the inventory status of these parts?

A: BAV101-GS18 has 8,749 pieces in stock, BAV101-GS08 has 9,300 pieces in stock, and BAS45AL,115 has 753 pieces in stock. Inventory levels are subject to change based on current supply conditions.
