BAS85 L1 Equivalent & Substitute Parts

Part Overview

The BAS85 L1 is a Schottky diode rated for 30 V DC reverse voltage and 200 mA average rectified current, manufactured by Taiwan Semiconductor Corporation in a Surface Mount Mini MELF package (DO-213AC, SOD-80). This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Schottky diodes in this voltage and current class are widely used in power supply circuits, signal detection, and reverse polarity protection applications. The obsolete status of the BAS85 L1 necessitates substitution with active production equivalents that maintain identical electrical performance and package compatibility.

Substitute Part Grouping Explanation

Substitution of the BAS85 L1 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 30 V
Current - Average Rectified (Io): 200 mA
Voltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mA
Package / Case: DO-213AC, MINI-MELF, SOD-80
Mounting Type: Surface Mount
Technology: Schottky

All substitute parts listed maintain these electrical specifications and physical package requirements. Variations in secondary parameters such as reverse leakage current (within the specified range), reverse recovery time, and capacitance do not preclude substitution when primary parameters are identical.

Packaging format variations (Cut Tape & Digi-Reel, Tape & Reel) represent different supply configurations of electrically and mechanically identical components and do not affect functional substitutability.

Engineering Selection Recommendations

All four substitute parts (BAS85,115, BAS85,135, BAS85-GS08, and BAS85-M-18) are active production components that maintain full electrical and mechanical equivalence to the obsolete BAS85 L1. Selection among these alternatives is based on procurement and application requirements:

BAS85,115 (Nexperia USA Inc.): Active status with high inventory availability (235,100 pcs). Supplied in Cut Tape & Digi-Reel format. ROHS3 compliant and REACH unaffected. Suitable for standard production applications.

BAS85,135 (Nexperia USA Inc.): Active status with moderate inventory (4,390 pcs). Supplied in Tape & Reel format. ROHS3 compliant and REACH unaffected. Suitable for high-volume automated assembly.

BAS85-GS08 (Vishay General Semiconductor): Active status with substantial inventory (16,100 pcs). Supplied in Cut Tape & Digi-Reel format. Maintains specified reverse recovery time of 5 ns. ROHS3 compliant and REACH unaffected. Suitable for applications requiring documented reverse recovery characteristics.

BAS85-M-18 (Vishay General Semiconductor): Active status with limited inventory (1,156 pcs). Supplied in Tape & Reel format. Qualified to AEC-Q101 automotive standard.

Frequently Asked Questions (FAQ)

Q: Can BAS85,115 be used as a direct replacement for BAS85 L1 in existing designs?

A: Yes. BAS85,115 maintains identical electrical specifications (30 V reverse voltage, 200 mA current rating, 800 mV forward voltage) and package configuration (DO-213AC, MINI-MELF, SOD-80 Surface Mount). The component is electrically and mechanically interchangeable.

Q: What is the difference between BAS85,115 and BAS85,135?

A: Both parts are manufactured by Nexperia USA Inc. and are electrically identical. The primary difference is packaging format: BAS85,115 is supplied in Cut Tape & Digi-Reel format, while BAS85,135 is supplied in Tape & Reel format. Selection depends on assembly equipment and procurement preferences.

Q: Why is BAS85-M-18 specified as automotive grade?

A: BAS85-M-18 carries AEC-Q101 automotive qualification, indicating compliance with automotive industry reliability and testing standards. This qualification is required for applications in automotive systems or designs subject to automotive supply chain requirements. Non-automotive applications do not require this variant.

Q: Are there differences in reverse leakage current between substitute parts?

A: BAS85,115 and BAS85,135 specify 2.3 µA reverse leakage at 25 V, while BAS85-GS08 and BAS85-M-18 specify 2 µA. Both values are within acceptable operating ranges for Schottky diodes in this class and do not affect functional substitutability in standard applications.

Q: Does the reverse recovery time specification affect substitution?

A: Reverse recovery time is specified as 5 ns for BAS85 L1, BAS85-GS08, and BAS85-M-18. BAS85,115 and BAS85,135 do not provide this specification in the available data. For applications where reverse recovery time is a critical design parameter, BAS85-GS08 or BAS85-M-18 are preferred. For general-purpose applications, all four substitutes are functionally equivalent.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all substitute parts use identical Surface Mount package configuration (DO-213AC, MINI-MELF, SOD-80). PCB footprints, solder pad layouts, and pick-and-place machine programming remain unchanged. No PCB redesign is required.

Q: What is the inventory status of each substitute part?

A: BAS85,115 has the highest availability (235,100 pcs), followed by BAS85-GS08 (16,100 pcs), BAS85,135 (4,390 pcs), and BAS85-M-18 (1,156 pcs). Inventory levels should be verified at time of procurement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts (BAS85,115, BAS85,135, BAS85-GS08, and BAS85-M-18) are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original BAS85 L1.
