Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS283-GS18 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 30 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
• Package / Case: SOD-80 Variant
• Mounting Type: Surface Mount
• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101

Allowable Variation Parameters:

• Current - Reverse Leakage @ Vr: Measured at different voltage points (200 V vs. 50 V) with identical leakage specification of 200 nA
• Capacitance @ Vr, F: Measured at different voltage points (1 V vs. 0 V) with minor variation (1.6 pF vs. 2 pF)

All identified substitute parts maintain identical electrical performance within the specified operating envelope and comply with automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

BAS283-GS08: This part is a direct parametric equivalent to the BAS283-GS18, sharing identical base product designation and electrical specifications. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain Active product status with full AEC-Q101 automotive qualification. The BAS283-GS08 is suitable for direct substitution in applications where the BAS283-GS18 is specified. Inventory availability for BAS283-GS08 is significantly higher (87,900 units) compared to BAS283-GS18 (716 units), making it the preferred selection for supply chain continuity.

LS101A-GS08: This part represents an alternative from the same manufacturer with identical core electrical ratings (60 V, 30 mA, 1 V forward voltage). The LS101A-GS08 carries the same automotive grade and AEC-Q101 qualification. Minor variations exist in reverse leakage measurement conditions (50 V vs. 200 V) and capacitance measurement point (0 V vs. 1 V), with capacitance values of 2 pF versus 1.6 pF. These variations remain within acceptable tolerances for small signal Schottky diode applications. The LS101A-GS08 is suitable for substitution where inventory of the primary BAS283 series is constrained. Inventory availability is 10,661 units.

Both substitute parts comply with ROHS3, maintain MSL 1 classification, and are unaffected by REACH regulations, matching the compliance profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can BAS283-GS08 be used as a direct replacement for BAS283-GS18?

A: Yes. Both parts share identical electrical specifications across all critical parameters: 60 V reverse voltage rating, 30 mA average rectified current, 1 V forward voltage at 15 mA, and SOD-80 surface mount packaging. Both are manufactured by Vishay and carry AEC-Q101 automotive qualification. The parts are functionally interchangeable.

Q: What is the difference between BAS283-GS18 and BAS283-GS08?

A: The primary difference is the packaging variant designation (GS18 vs. GS08), which reflects different tape and reel configurations for automated assembly. Electrical performance and component specifications are identical. The GS08 variant has significantly higher inventory availability.

Q: Is LS101A-GS08 compatible with BAS283-GS18 in automotive applications?

A: Yes. The LS101A-GS08 meets all mandatory electrical requirements and carries identical automotive grade and AEC-Q101 qualification. Minor variations in reverse leakage measurement conditions and capacitance values are within acceptable tolerances for small signal Schottky diode operation. Both parts are suitable for automotive circuit designs.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use SOD-80 QuadroMELF surface mount packaging. They are mechanically and electrically compatible for PCB assembly without design modifications.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity classification, and are REACH unaffected. Automotive grade and AEC-Q101 qualification are maintained across all parts.

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

A: BAS283-GS18 and BAS283-GS08 specify 200 nA reverse leakage at 200 V. LS101A-GS08 specifies 200 nA reverse leakage at 50 V. Both measurements indicate identical leakage performance; the difference reflects the test voltage point used for characterization. This variation does not affect circuit performance.

Q: Can I use LS101A-GS08 if BAS283 parts are unavailable?

A: Yes. The LS101A-GS08 provides equivalent electrical performance with identical voltage and current ratings, forward voltage characteristics, and automotive qualification. It is a valid substitute when BAS283 series inventory is depleted.
