Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV23S-7 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode Configuration: 1 Pair Series Connection (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io) (per Diode): 400 mA minimum
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA or lower
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns or lower
• Current - Reverse Leakage @ Vr: 100 nA @ 200 V or lower

Mechanical Compatibility Requirements:

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

Substitute parts are grouped into two categories:

Parametric Equivalents (Diodes Incorporated): BAV23S-7-F, BAV23SQ-13-F, and BAV23SQ-7-F meet or exceed all electrical specifications of the BAV23S-7 with identical package geometry. These parts are active products with RoHS3 compliance.

Manufacturer Recommended Alternatives: BAV23S (Good-Ark Semiconductor), BAV23S,215 (Nexperia USA Inc.), and BAV23S-TP (Micro Commercial Co) provide functional equivalence with variations in current rating and compliance status. These parts maintain the same package footprint and core electrical characteristics within acceptable design margins.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Drop-In Replacement):

BAV23S-7-F, BAV23SQ-13-F, and BAV23SQ-7-F are manufactured by Diodes Incorporated and provide complete electrical and mechanical equivalence to the BAV23S-7. All three parts maintain identical specifications for voltage, current, recovery time, and temperature range. These parts are active products with RoHS3 compliance and are available in Tape & Reel packaging suitable for production environments. Selection among these three is determined by packaging availability and inventory requirements.

Functional Alternatives with Current Derating:

BAV23S (Good-Ark Semiconductor), BAV23S,215 (Nexperia USA Inc.), and BAV23S-TP (Micro Commercial Co) are suitable for applications where the average rectified current requirement does not exceed 225 mA per diode. These parts maintain the same package footprint, diode configuration, and fast recovery characteristics. All three are active products with RoHS3 compliance. The Good-Ark BAV23S offers enhanced reverse voltage rating (250 V). The Nexperia BAV23S,215 specifies lower forward voltage (1 V @ 100 mA). The Micro Commercial BAV23S-TP maintains full temperature range compatibility (-65 to 150°C).

Compliance Considerations:

All substitute parts listed are RoHS3 compliant, addressing regulatory requirements not met by the discontinued BAV23S-7. For applications requiring RoHS compliance, any of the listed alternatives are suitable. For applications with no RoHS requirement, the parametric equivalents from Diodes Incorporated remain the preferred choice due to identical electrical specifications and active product status.

Frequently Asked Questions (FAQ)

Q: Can BAV23S-7-F be used as a direct replacement for BAV23S-7?

A: Yes. BAV23S-7-F is a parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications, package geometry, and diode configuration. The primary difference is product status (active vs. discontinued) and packaging format (Tape & Reel vs. bulk). No circuit modifications are required.

Q: What is the difference between BAV23S-7-F, BAV23SQ-13-F, and BAV23SQ-7-F?

A: All three parts are manufactured by Diodes Incorporated and meet identical electrical specifications. The differences are in manufacturing date codes and internal quality designations (indicated by the suffix). All are suitable for direct substitution. Selection is based on availability and packaging requirements.

Q: Can I use BAV23S (Good-Ark) or BAV23S,215 (Nexperia) if my application requires 400 mA?

A: No. These alternatives are rated for 225 mA average rectified current per diode, which is below the 400 mA specification of the BAV23S-7. Use only if your actual circuit current requirement does not exceed 225 mA per diode.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the TO-236-3, SC-59, SOT-23-3 package, which provides identical pin spacing and land pattern compatibility. No PCB redesign is required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel packaging is supplied in shorter tape segments. Both formats are compatible with standard surface mount assembly processes. Selection depends on production volume and equipment capability.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are RoHS3 compliant. The original BAV23S-7 is RoHS non-compliant. If RoHS compliance is required for your application, any of the listed alternatives satisfy this requirement.

Q: What is the minimum reverse voltage rating I need for a substitute part?

A: The minimum acceptable reverse voltage rating is 200 V to match the BAV23S-7 specification. BAV23S (Good-Ark) offers 250 V, which exceeds the requirement and provides additional design margin. All other alternatives maintain the 200 V rating.

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

A: Yes, provided all parts meet your circuit's electrical requirements. All listed parametric equivalents and alternatives maintain the same diode configuration, package footprint, and fast recovery characteristics. Mixing is acceptable from an engineering standpoint, though single-source procurement is recommended for supply chain consistency.

Q: What is the operating temperature range for each substitute?

A: BAV23S-7-F, BAV23SQ-13-F, BAV23SQ-7-F, and BAV23S-TP all operate from -65°C to 150°C. BAV23S (Good-Ark) operates from -55°C to 150°C. BAV23S,215 (Nexperia) specifies 150°C maximum without a minimum temperature. For applications requiring full -65°C to 150°C range, use Diodes Incorporated or Micro Commercial Co alternatives.
