Substitute Part Grouping Explanation

Substitution of the BAS40-06-7 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Diode Configuration: 1 Pair Common Anode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 40 V minimum
Mounting Type: Surface Mount
Package / Case: TO-236-3, SC-59, SOT-23-3 (or compatible surface mount package)

Current Rating Consideration:

Current - Average Rectified (Io) (per Diode): 200 mA or greater

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (200 mA Rating) Parts that maintain the exact 200 mA current rating with identical or superior electrical characteristics. These parts are pin-compatible and functionally interchangeable without circuit modification.

Category 2: Parametric Equivalents (120 mA to 300 mA Rating) Parts that operate within the 40 V reverse voltage specification but with different current ratings. These parts maintain the same package and configuration but may require circuit evaluation if the application demands the full 200 mA rating. Parts with current ratings of 120 mA are suitable for applications where the circuit current requirement does not exceed 120 mA. Parts with current ratings of 250 mA to 300 mA provide additional current margin.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Specifications):

BAS40-06-7-F and BAS40-06Q-7-F are direct replacements for the discontinued BAS40-06-7. Both parts maintain 200 mA current rating, 40 V reverse voltage, and SOT-23-3 packaging. BAS40-06-7-F is supplied in Tape & Reel packaging and is ROHS3 compliant with active product status. BAS40-06Q-7-F includes AEC-Q101 automotive qualification and is also ROHS3 compliant. Both parts are suitable for applications requiring the full 200 mA specification without circuit modification.

BAT721A,215 (Nexperia USA Inc.) provides an alternative direct replacement with 200 mA rating and 40 V reverse voltage in SOT-23-3 package. This part is ROHS3 compliant and active. Forward voltage characteristics differ at the specified test point (550 mV @ 200 mA versus 1 V @ 40 mA), requiring circuit evaluation for applications sensitive to forward voltage drop.

Parametric Equivalents (Reduced Current Rating):

BAS40-06,215 (Nexperia USA Inc.), BAS40-06LT1G (onsemi), BAS4006E6327HTSA1, and BAS4006E6433HTMA1 (Infineon Technologies) are parametric equivalents with 120 mA current rating. These parts are suitable for applications where circuit current does not exceed 120 mA. All are ROHS3 compliant and active. The Infineon parts feature 100 ps reverse recovery time compared to the original 5 ns specification. BAS40-06,215 carries AEC-Q100 automotive qualification.

Parametric Equivalents (Increased Current Rating):

BAT6406E6327HTSA1 (Infineon Technologies) provides 250 mA current rating with 40 V reverse voltage in SOT-23-3 package. This part is ROHS3 compliant, active, and carries AEC-Q101 automotive qualification. Forward voltage is specified at 750 mV @ 100 mA.

BAT54AFILM (STMicroelectronics) provides 300 mA current rating with 40 V reverse voltage in SOT-23-3 package. This part is ROHS3 compliant and active. Forward voltage is specified at 900 mV @ 100 mA. BAT54AWFILM is the same electrical equivalent but in SC-70, SOT-323 package, which is not pin-compatible with the original SOT-23-3 footprint.

Frequently Asked Questions (FAQ)

Q: Can BAS40-06-7-F be used as a direct replacement for BAS40-06-7?

A: Yes. BAS40-06-7-F maintains identical electrical specifications: 200 mA current rating, 40 V reverse voltage, 1 V forward voltage @ 40 mA, 5 ns reverse recovery time, and SOT-23-3 package. The primary difference is product status (active versus discontinued) and RoHS compliance (ROHS3 compliant). No circuit modification is required.

Q: What is the difference between BAS40-06-7-F and BAS40-06Q-7-F?

A: Both parts are electrically identical with 200 mA rating and 40 V reverse voltage in SOT-23-3 package. BAS40-06Q-7-F includes AEC-Q101 automotive qualification, making it suitable for automotive applications. BAS40-06-7-F is the standard industrial grade version. Selection depends on application requirements.

Q: Can I use a 120 mA rated part (BAS40-06,215, BAS40-06LT1G) in place of the 200 mA BAS40-06-7?

A: Only if the circuit current requirement does not exceed 120 mA. The 120 mA parts are parametric equivalents with the same 40 V reverse voltage and SOT-23-3 package. If the application requires the full 200 mA capability, these parts are not suitable. Circuit analysis is required to confirm maximum current demand.

Q: What is the advantage of BAT6406E6327HTSA1 or BAT54AFILM over the original BAS40-06-7?

A: Both parts provide higher current ratings (250 mA and 300 mA respectively) while maintaining 40 V reverse voltage and SOT-23-3 package compatibility. These parts offer additional current margin for applications with higher current demands. BAT6406E6327HTSA1 includes AEC-Q101 automotive qualification. Forward voltage characteristics differ and should be evaluated for applications sensitive to voltage drop.

Q: Why does BAT54AWFILM have a different package (SOT-323) than the original BAS40-06-7 (SOT-23-3)?

A: BAT54AWFILM is supplied in SC-70, SOT-323 package, which is not pin-compatible with the original SOT-23-3 footprint. This part cannot be used as a direct board-level replacement without PCB redesign. BAT54AFILM is the equivalent part in SOT-23-3 package.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original BAS40-06-7 is RoHS non-compliant. If RoHS compliance is a requirement, any of the listed active substitute parts satisfy this criterion.

Q: What is the difference between Infineon BAS4006E6327HTSA1 and BAS4006E6433HTMA1?

A: Both parts are electrically identical with 120 mA rating, 40 V reverse voltage, 100 ps reverse recovery time, and SOT-23-3 package. The difference is in the supplier device package designation (PG-SOT23 for both) and internal manufacturing codes. Both are ROHS3 compliant and active. Selection between these parts depends on supplier availability and internal traceability requirements.

Q: Can I substitute BAT721A,215 for BAS40-06-7?

A: BAT721A,215 is a direct current rating equivalent (200 mA) with 40 V reverse voltage and SOT-23-3 package. However, forward voltage characteristics differ: BAT721A,215 is specified at 550 mV @ 200 mA, while BAS40-06-7 is specified at 1 V @ 40 mA. For applications where forward voltage drop is critical, circuit evaluation is required to confirm compatibility.

Q: Which substitute part should I select for a new design?

A: For new designs requiring 200 mA capability, BAS40-06-7-F or BAS40-06Q-7-F are recommended. Both are active, ROHS3 compliant, and maintain the original electrical specifications. BAS40-06Q-7-F is preferred for automotive applications due to AEC-Q101 qualification. For applications with lower current requirements (≤120 mA), BAS40-06LT1G (onsemi) or BAS40-06,215 (Nexperia) offer active alternatives with extended temperature range (150°C maximum junction temperature).
