Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40-05-HF is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Reverse Recovery Time (trr): 5 ns
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Current - Reverse Leakage @ Vr: 100 nA to 200 nA @ 30 V (lower leakage is acceptable)
• Operating Temperature - Junction: Maximum rating of 125°C or extended range -55°C to 125°C (extended range is acceptable)
• Supplier Device Package designation: SOT-23 or SOT-23-3 (equivalent designations)
• Additional certifications (AEC-Q101 Automotive qualification) do not disqualify substitution

All identified substitute parts meet these equivalence criteria and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are electrically and mechanically equivalent to the BAS40-05-HF and are suitable for direct replacement in applications requiring Schottky diode arrays with 40 V reverse voltage and 200 mA current ratings in SOT-23-3 surface mount packaging.

BAS40-05-7-F (Diodes Incorporated): This part provides parametric equivalence with extended operating temperature range (-55°C to 125°C) compared to the BAS40-05-HF. ROHS3 compliance and MSL 1 rating are maintained. This part is recommended for applications requiring wider temperature operation.

BAS40-05-E3-08 (Vishay General Semiconductor - Diodes Division): This part provides parametric equivalence with reduced reverse leakage current (100 nA @ 30 V versus 200 nA @ 30 V). ROHS3 compliance and MSL 1 rating are maintained. This part is recommended for applications where lower leakage current is beneficial.

BAS40-05-TP (Micro Commercial Co): This part provides parametric equivalence with extended operating temperature range (-55°C to 125°C). ROHS3 compliance and MSL 1 rating are maintained. Supplier device package designation is SOT-23 (equivalent to SOT-23-3).

BAS40-05Q-7-F (Diodes Incorporated): This part provides parametric equivalence with extended operating temperature range (-55°C to 125°C) and includes AEC-Q101 automotive qualification. ROHS3 compliance and MSL 1 rating are maintained. This part is recommended for automotive applications requiring AEC-Q101 certification.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can BAS40-05-7-F be used as a direct replacement for BAS40-05-HF?

A: Yes. BAS40-05-7-F meets all mandatory equivalence parameters including diode configuration, Schottky technology, 40 V reverse voltage, 200 mA current rating, 1 V forward voltage, 5 ns reverse recovery time, and SOT-23-3 packaging. The extended operating temperature range (-55°C to 125°C) is an allowable variation that does not prevent substitution.

Q: What is the difference between BAS40-05-E3-08 and other substitutes?

A: BAS40-05-E3-08 is distinguished by lower reverse leakage current (100 nA @ 30 V) compared to the BAS40-05-HF and most other substitutes (200 nA @ 30 V). All other electrical and mechanical parameters are equivalent. Lower leakage current may be advantageous in low-power or precision applications.

Q: Is BAS40-05Q-7-F suitable for non-automotive applications?

A: Yes. BAS40-05Q-7-F meets all electrical and mechanical equivalence parameters for the BAS40-05-HF. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in non-automotive applications. This part is suitable for any application requiring the specified electrical characteristics.

Q: Are there package compatibility differences between these substitutes?

A: All substitute parts use TO-236-3, SC-59, SOT-23-3 package designations. BAS40-05-TP uses the equivalent SOT-23 supplier device package designation. These designations refer to the same physical package with identical pin configuration, spacing, and footprint. No PCB layout modifications are required.

Q: What is the significance of ROHS3 compliance and MSL 1 rating?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements and contains no restricted materials. MSL 1 (Unlimited) rating indicates the part has unlimited shelf life and does not require special moisture-controlled storage or handling. All substitute parts maintain these compliance levels.

Q: Can I substitute BAS40-05-HF with any of these parts in existing designs?

A: Yes. All identified substitute parts are parametrically equivalent across the critical electrical and mechanical parameters that determine functional compatibility. No circuit modifications, PCB redesign, or firmware changes are required. Direct component substitution is supported.

Q: What inventory levels are available for each substitute?

A: BAS40-05-7-F (Diodes Incorporated) has 47,400 pieces in stock. BAS40-05-E3-08 (Vishay) has 9,400 pieces in stock. BAS40-05-TP (Micro Commercial Co) has 3,548 pieces in stock.
