BAS40-06/ZLR Equivalent & Substitute Parts

Part Overview

The BAS40-06/ZLR is a Schottky diode array manufactured by Nexperia USA Inc., configured as 1 pair common anode with a 40 V DC reverse voltage rating and 120 mA average rectified current per diode. The component is housed in a TO-236-3 (SC-59, SOT-23-3) surface mount package and is qualified to AEC-Q101 automotive standards with ROHS3 compliance.

The BAS40-06/ZLR is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure component availability for new production and repair applications. Active equivalent parts from Nexperia, Rohm Semiconductor, and onsemi provide identical or superior electrical performance with current manufacturing status.

Engineering Selection Recommendations

Primary Recommendation for Active Replacement:

BAS40-06,215 (Nexperia USA Inc.) is the direct successor to the obsolete BAS40-06/ZLR. Both components are manufactured by Nexperia and maintain identical electrical specifications and package geometry. The BAS40-06,215 is actively produced with 13,608 units in stock, ensuring supply continuity. This part is qualified to AEC-Q100 automotive standards.

Alternative Active Replacements:

BAS40-06,235 (Nexperia USA Inc., Tape & Reel packaging) provides identical electrical performance and is actively produced with 675 units available. Selection between BAS40-06,215 and BAS40-06,235 depends on packaging format requirements (Cut Tape vs. Tape & Reel).

Cross-Manufacturer Alternatives:

Rohm Semiconductor parts (BAS40-06HMT116, BAS40-06HYFHT116, BAS40-06HYT116, BAS40-06HMFHT116) are qualified to AEC-Q101 automotive standards and maintain full electrical equivalence. These parts are actively produced with inventory ranging from 2,300 to 4,028 units. Selection among Rohm variants depends on packaging format and supplier device package designation (SSD3 vs. SOT-23).

onsemi parts (SBAS40-06LT1G, BAS40-06LT1G) are actively produced with high inventory availability (38,300 and 65,300 units respectively). SBAS40-06LT1G carries AEC-Q101 qualification and is recommended for automotive applications. BAS40-06LT1G lacks explicit automotive qualification designation in the provided data.

Selection Criteria:

For automotive applications requiring AEC-Q101 qualification: Select from Rohm Semiconductor variants or SBAS40-06LT1G (onsemi)
For general-purpose applications: Any listed substitute part is electrically equivalent
For supply chain optimization: onsemi parts offer highest inventory availability
For packaging format requirements: Verify supplier device package designation and tape format compatibility with assembly equipment

Frequently Asked Questions (FAQ)

Q: Can BAS40-06,215 directly replace BAS40-06/ZLR in existing designs?

A: Yes. BAS40-06,215 is electrically and mechanically equivalent to BAS40-06/ZLR. Both components share identical diode configuration, voltage rating (40 V), current rating (120 mA per diode), forward voltage (1 V @ 40 mA), and package geometry (TO-236-3, SC-59, SOT-23-3). Pin-to-pin compatibility is confirmed.

Q: What is the difference between AEC-Q100 and AEC-Q101 qualification?

A: Both qualifications indicate automotive-grade reliability standards. AEC-Q100 and AEC-Q101 are distinct qualification levels established by the Automotive Electronics Council. The provided data does not specify functional differences between these qualifications for this component category. Selection should be based on design requirements and customer specifications.

Q: Are Rohm Semiconductor and onsemi parts compatible with Nexperia designs?

A: Yes. All substitute parts maintain identical electrical specifications and package outlines. Functional compatibility is confirmed across all listed manufacturers. PCB layout and assembly processes require no modification.

Q: What is the significance of different supplier device package designations (TO-236AB, SSD3, SOT-23)?

A: These designations refer to manufacturer-specific package naming conventions. All designations correspond to the same physical package outline: TO-236-3, SC-59, SOT-23-3. Mechanical compatibility is maintained across all variants. Supplier device package designation does not affect electrical performance or PCB footprint compatibility.

Q: Which substitute part offers the best supply availability?

A: SBAS40-06LT1G (onsemi) offers the highest inventory with 38,300 units in stock. BAS40-06LT1G (onsemi) provides even greater availability at 65,300 units. Both parts are actively produced. For automotive applications, SBAS40-06LT1G is recommended due to AEC-Q101 qualification.

Q: Can I mix different manufacturers in the same production batch?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing manufacturers within a single production batch does not affect circuit performance or reliability. However, design documentation and bill of materials should clearly specify approved part numbers for traceability and future service requirements.

Q: What packaging formats are available for these substitute parts?

A: Substitute parts are available in three packaging formats: Cut Tape (CT) & Digi-Reel, Tape & Reel (TR), and individual component formats. Selection depends on assembly equipment compatibility and procurement volume requirements. Electrical performance is identical across all packaging formats.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
