BAS85-L0 Equivalent & Substitute Parts

Part Overview

The BAS85-L0 is a Schottky diode rated for 30 V DC reverse voltage and 200 mA average rectified current in a Surface Mount Mini MELF package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and production continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while supporting the same package form factor and mounting technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS85-L0 is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io): 200 mA minimum
• Technology: Schottky diode
• Mounting Type: Surface Mount
• Package / Case: DO-213AC, MINI-MELF, SOD-80 compatible

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mA or lower
• Reverse Recovery Time (trr): 5 ns or lower
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V or lower
• Capacitance @ Vr, F: 10 pF @ 1V, 1MHz or lower
• Operating Temperature - Junction (Max): 125°C or higher
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet or exceed these criteria and are classified as active products, ensuring design continuity and supply chain availability.
