Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV99Q-7-F are classified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Diode Configuration: 1 Pair Series Connection
• Package / Case: TO-236-3, SC-59, SOT-23-3 (surface mount)
• Voltage - DC Reverse (Vr) (Max): 75 V or higher
• Current - Average Rectified (Io) (per Diode): 300 mA or higher
• Reverse Recovery Time (trr): 4 ns
• Operating Temperature - Junction: -65°C to 150°C minimum range

Parametric Equivalent Parts (BAV99-13-F, BAV99-7-F, BAV99Q-13-F, MMBD7000-7-F) meet all critical electrical parameters and package requirements. These parts are direct functional replacements with identical voltage, current, and thermal specifications.

Direct Manufacturer Equivalent (BAV99,215 from Nexperia USA Inc.) provides higher voltage rating (100 V) and lower current rating (215 mA), suitable for applications with reduced current requirements or higher voltage margins.

MFR Recommended Alternatives (BAV99-AU_R1_000A1 from Panjit International Inc., TBAV99,LM from Toshiba Semiconductor and Storage) have reduced current ratings (150 mA and 100 mA respectively) and different speed classifications, applicable only to designs with lower current demands.

Parameter Comparison

Engineering Selection Recommendations

Full Parametric Equivalents (Recommended for Direct Replacement):

BAV99-13-F, BAV99-7-F, BAV99Q-13-F, and MMBD7000-7-F are complete electrical and mechanical equivalents to BAV99Q-7-F. All parts maintain identical voltage, current, and thermal specifications. Selection among these parts is determined by packaging format availability and inventory requirements. BAV99-7-F offers the highest inventory availability (269,400 pcs) in Cut Tape format. BAV99Q-13-F and MMBD7000-7-F are available in Tape & Reel format matching the original part's packaging type.

Higher Voltage Alternative (BAV99,215):

The BAV99,215 from Nexperia USA Inc. provides 100 V reverse voltage rating with 215 mA current capacity. This part is suitable for applications requiring higher voltage margins or where current requirements do not exceed 215 mA. The part is AEC-Q101 qualified for automotive applications and maintains identical package and thermal specifications.

Reduced Current Alternatives (BAV99-AU_R1_000A1, TBAV99,LM):

These parts are applicable only to designs with maximum current requirements below 150 mA and 100 mA respectively. BAV99-AU_R1_000A1 maintains 75 V voltage rating with AEC-Q101 automotive qualification. TBAV99,LM provides 80 V rating but is limited to 100 mA operation and has a maximum junction temperature of 125°C. Both parts are classified as Small Signal devices and are not suitable for applications requiring fast recovery switching characteristics above 200 mA.

Frequently Asked Questions (FAQ)

Q: Can BAV99-7-F be used as a direct replacement for BAV99Q-7-F?

A: Yes. BAV99-7-F is a parametric equivalent with identical electrical specifications (75 V, 300 mA, 4 ns recovery time). The primary difference is packaging format: BAV99-7-F is supplied in Cut Tape & Digi-Reel® format while BAV99Q-7-F is supplied in Tape & Reel format. Both are surface mount SOT-23-3 packages suitable for automated assembly.

Q: What is the difference between BAV99Q-13-F and BAV99-7-F?

A: Both parts are parametric equivalents with identical electrical and thermal specifications. The designation difference (Q vs. standard, 13 vs. 7) reflects different manufacturing batches or tape configurations. Both are Tape & Reel packaged and suitable for high-volume automated placement.

Q: Can MMBD7000-7-F replace BAV99Q-7-F?

A: Yes. MMBD7000-7-F meets all critical electrical parameters: 75 V reverse voltage, 300 mA current capacity, 4 ns recovery time, and -65°C to 150°C operating range. The reverse leakage current is lower (1 µA @ 50 V vs. 2.5 µA @ 75 V), which is a performance advantage. Package and mounting type are identical.

Q: Is BAV99,215 from Nexperia a suitable substitute?

A: BAV99,215 is suitable only for applications where the design current requirement does not exceed 215 mA. The part provides higher voltage rating (100 V) and lower current capacity. It is AEC-Q101 qualified and maintains identical package specifications. Use this part only if the application current budget is below 215 mA.

Q: Can BAV99-AU_R1_000A1 or TBAV99,LM be used in place of BAV99Q-7-F?

A: These parts are not suitable for direct replacement. BAV99-AU_R1_000A1 is limited to 150 mA and TBAV99,LM to 100 mA, both classified as Small Signal devices. They are applicable only to designs with significantly reduced current requirements. TBAV99,LM additionally has a lower maximum junction temperature (125°C vs. 150°C).

Q: What packaging formats are available for equivalent parts?

A: Equivalent parts are available in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel®. BAV99Q-7-F, BAV99Q-13-F, and MMBD7000-7-F are supplied in Tape & Reel format. BAV99-13-F and BAV99-7-F are supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly equipment compatibility and volume requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the difference between Fast Recovery and Small Signal speed classifications?

A: Fast Recovery devices (≤ 500ns, > 200mA) are optimized for switching applications with currents above 200 mA and have guaranteed fast switching characteristics. Small Signal devices (≤ 200mA, Any Speed) are not guaranteed for fast recovery performance and are suitable only for low-current applications. BAV99Q-7-F is Fast Recovery rated; BAV99-AU_R1_000A1 and TBAV99,LM are Small Signal rated.
