BAS40-05/ZLR Equivalent & Substitute Parts

Part Overview

The BAS40-05/ZLR is a Schottky diode array manufactured by NXP USA Inc., configured as 1 pair common cathode with a 40 V DC reverse voltage rating and 120 mA average rectified current per diode. The device is housed in a Surface Mount TO-236-3 (SC-59, SOT-23-3) package and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40-05/ZLR is determined by strict equivalence across the following parameters:

Electrical Parameters (Critical for Substitution):

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 120 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Current - Reverse Leakage @ Vr: 10 µA @ 40 V
• Operating Temperature - Junction (Max): 150°C
• Speed Classification: Small Signal ≤ 200 mA (Io), Any Speed

Mechanical Parameters (Critical for Substitution):

• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain identical electrical and mechanical specifications. Variations in packaging format (Cut Tape, Digi-Reel, Tape & Reel) and supplier device package designations do not affect functional equivalence. Automotive-grade variants with AEC-Q101 qualification provide additional qualification but remain electrically and mechanically equivalent.

Engineering Selection Recommendations

Primary Recommendation: BAS40-05,215 (Nexperia USA Inc.)

BAS40-05,215 is the manufacturer-recommended substitute for the obsolete BAS40-05/ZLR. This part is active in production status and maintains complete electrical and mechanical equivalence. It is available in Cut Tape and Digi-Reel packaging formats with 9,300 pieces in current inventory. This part is suitable for all applications previously using the BAS40-05/ZLR without design modification.

Secondary Recommendation: BAS40-05,235 (Nexperia USA Inc.)

BAS40-05,235 is a parametric equivalent available in Tape & Reel packaging format with 7,717 pieces in inventory. This part maintains identical electrical specifications and is suitable for high-volume production environments requiring reel packaging.

Automotive Applications: BAS40-05HMFHT116 or BAS40-05HYFHT116 (Rohm Semiconductor)

For applications requiring automotive-grade components with AEC-Q101 qualification, BAS40-05HMFHT116 (Cut Tape & Digi-Reel, 1,163 pieces) and BAS40-05HYFHT116 (Tape & Reel, 6,789 pieces) are available. Both parts maintain identical electrical and mechanical specifications while providing automotive qualification. BAS40-05HYFHT116 offers higher inventory availability.

General Production: BAS40-05HYT116 (Rohm Semiconductor)

BAS40-05HYT116 is available in Tape & Reel packaging with 2,773 pieces in inventory. This part maintains complete electrical and mechanical equivalence and is suitable for standard industrial applications.

Selection Criteria:

• Packaging requirement: Choose Cut Tape/Digi-Reel for lower-volume or manual assembly; choose Tape & Reel for automated high-volume production.
• Automotive compliance: Select Rohm Semiconductor variants (BAS40-05HMFHT116 or BAS40-05HYFHT116) if AEC-Q101 qualification is required.
• Inventory availability: BAS40-05,215 and BAS40-05HYFHT116 offer the highest stock levels.
• Manufacturer preference: Nexperia parts are direct successors from the original NXP product line; Rohm parts provide automotive-qualified alternatives.

Frequently Asked Questions (FAQ)

Q: Can BAS40-05,215 be used as a direct replacement for BAS40-05/ZLR?

A: Yes. BAS40-05,215 is the manufacturer-recommended substitute and maintains identical electrical and mechanical specifications. No design modification is required. The part is pin-compatible and functionally equivalent in all applications.

Q: What is the difference between the Nexperia and Rohm substitute parts?

A: All substitute parts maintain identical electrical specifications (40 V reverse voltage, 120 mA current rating, 1 V forward voltage at 40 mA, 10 µA reverse leakage at 40 V, 150°C maximum junction temperature). The primary differences are manufacturer, packaging format, and automotive qualification. Rohm variants (BAS40-05HMFHT116, BAS40-05HYFHT116) include AEC-Q101 automotive qualification; Nexperia variants do not.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) affects only handling, storage, and assembly processes. All variants maintain identical electrical and mechanical specifications. Selection should be based on production volume and assembly equipment compatibility.

Q: Are the Rohm automotive-grade parts suitable for non-automotive applications?

A: Yes. Automotive-grade parts with AEC-Q101 qualification meet or exceed standard industrial specifications. They are fully compatible with non-automotive applications and provide additional qualification margin.

Q: What is the significance of the SOT-23 package designation?

A: SOT-23 (also designated TO-236-3 or SC-59) is the physical package form factor. All substitute parts use this identical package, ensuring mechanical compatibility with existing PCB layouts and assembly processes. No footprint modification is required.

Q: Can I mix different substitute parts in the same production run?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications. However, for traceability and quality control purposes, it is standard practice to maintain consistent part sourcing within a single production batch.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All substitute parts listed are ROHS3 compliant.

Q: Is the 10 µA reverse leakage specification critical for my application?

A: Reverse leakage current is a key Schottky diode parameter affecting circuit performance in high-impedance applications. All substitute parts maintain the identical 10 µA @ 40 V specification, ensuring equivalent performance in leakage-sensitive circuits.

Q: What is the Moisture Sensitivity Level (MSL) 1 rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The component can be stored indefinitely under normal conditions without special moisture control measures.
