BAS281-GS18 Equivalent & Substitute Parts

Part Overview

The BAS281-GS18 is an automotive-grade Schottky diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 40 V DC reverse voltage with a 30 mA average rectified current rating. The device is qualified to AEC-Q101 automotive standards and is RoHS3 compliant. The BAS281-GS18 is classified as an active product with continuous availability. Substitute parts are identified when original inventory is unavailable or when procurement lead times require alternative sourcing from the same manufacturer's product line while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS281-GS18 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

• Voltage Rating: DC reverse voltage of 40 V maximum
• Current Rating: Average rectified current of 30 mA
• Forward Voltage Characteristics: 1 V maximum at 15 mA forward current
• Reverse Leakage: 200 nA at 200 V
• Junction Capacitance: 1.6 pF at 1 V, 1 MHz
• Package: SOD-80 QuadroMELF surface mount configuration
• Automotive Qualification: AEC-Q101 certification
• Temperature Rating: 125°C maximum junction temperature
• Compliance: RoHS3 compliant, REACH unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The BAS281-GS08 meets all specified criteria and is therefore a valid substitute for the BAS281-GS18.
