BAV101-GS08 Equivalent & Substitute Parts

Part Overview

The BAV101-GS08 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-GS08 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory constraints necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV101-GS08 are classified based on electrical parameter compatibility and mechanical interchangeability. 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 direct functional replacements with no circuit redesign required.

Manufacturer Recommended Alternatives provide functional equivalence with allowable parameter variations that remain within acceptable application tolerances. These parts may exhibit different recovery characteristics or leakage specifications while maintaining the same voltage and current ratings and package compatibility.

The key parameters determining substitution eligibility are:

• 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 compatible
• Mounting Type: Must be Surface Mount
• Operating Temperature - Junction: Must support 175°C maximum

Parameter Comparison

Engineering Selection Recommendations

BAV101-GS18 is a parametric equivalent to the BAV101-GS08. Both devices are manufactured by Vishay General Semiconductor and share identical electrical specifications including 100 V reverse voltage, 250 mA average rectified current, 50 ns reverse recovery time, and 1.5 pF capacitance. Both carry automotive-grade qualification under AEC-Q101 and are ROHS3 compliant with unlimited moisture sensitivity. The BAV101-GS18 is suitable for direct substitution in all applications where the BAV101-GS08 is specified.

BAS45AL,115 is a manufacturer-recommended alternative manufactured by Nexperia USA Inc. This device provides higher reverse voltage rating (125 V versus 100 V) and superior reverse leakage characteristics (1 nA versus 100 nA). However, the BAS45AL,115 exhibits standard recovery characteristics (1.5 µs reverse recovery time) compared to the fast recovery specification (50 ns) of the BAV101-GS08, and higher capacitance (4 pF versus 1.5 pF). The BAS45AL,115 is suitable for applications where fast recovery is not a critical requirement. All three devices maintain identical forward voltage drop (1 V @ 100 mA), package compatibility (SOD-80 MiniMELF), and maximum junction temperature (175°C). All substitute parts are active production items with ROHS3 compliance and unlimited moisture sensitivity.

Frequently Asked Questions (FAQ)

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

A: Yes. The BAV101-GS18 is a parametric equivalent with identical electrical specifications. Both devices share the same reverse voltage (100 V), average rectified current (250 mA), forward voltage drop (1 V @ 100 mA), reverse recovery time (50 ns), reverse leakage current (100 nA @ 100 V), and capacitance (1.5 pF @ 0V, 1MHz). Both are housed in SOD-80 MiniMELF packages and carry AEC-Q101 automotive qualification. No circuit modifications are required.

Q: What are the limitations of using BAS45AL,115 as a substitute?

A: The BAS45AL,115 exhibits standard recovery characteristics with 1.5 µs reverse recovery time, compared to the 50 ns fast recovery specification of the BAV101-GS08. Applications requiring fast switching or high-frequency operation may experience performance degradation. Additionally, the BAS45AL,115 has higher capacitance (4 pF versus 1.5 pF), which may affect high-frequency circuit behavior. The BAS45AL,115 is suitable for general-purpose rectification applications where recovery speed is not critical.

Q: Are all substitute parts automotive-qualified?

A: The BAV101-GS08 and BAV101-GS18 both carry automotive-grade qualification under AEC-Q101. The BAS45AL,115 does not list automotive qualification in the provided specifications. For applications requiring automotive-grade components, the BAV101-GS18 is the preferred substitute.

Q: Do all parts have the same package compatibility?

A: Yes. The BAV101-GS08, BAV101-GS18, and BAS45AL,115 are all housed in DO-213AC, MINI-MELF, SOD-80 packages and are surface mount devices. All three parts are mechanically interchangeable on standard PCB layouts designed for SOD-80 MiniMELF components.

Q: What is the difference in reverse leakage current between the parts?

A: The BAV101-GS08 and BAV101-GS18 both exhibit 100 nA reverse leakage current at 100 V. The BAS45AL,115 exhibits significantly lower reverse leakage of 1 nA at 125 V. Lower leakage current may be beneficial in low-power or high-impedance applications, but this difference is not critical for standard rectification circuits.

Q: Are all parts ROHS3 compliant?

A: Yes. The BAV101-GS08, BAV101-GS18, and BAS45AL,115 are all ROHS3 compliant with unlimited moisture sensitivity (MSL 1). All parts are suitable for lead-free soldering processes and meet environmental compliance requirements.
