Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV99-7-F-31 are qualified based on electrical and mechanical parameter equivalence within the diode rectifier category. All substitute parts maintain identical specifications across the following critical parameters:

• Diode Configuration: 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 75 V
• Current - Average Rectified (Io) (per Diode): 300 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Recovery Time (trr): 4 ns
• Operating Temperature - Junction: -65°C ~ 150°C
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts differ in product status (active vs. obsolete), packaging format (Cut Tape & Digi-Reel vs. Tape & Reel), and inventory availability. The MMBD7000-7-F variant exhibits a lower reverse leakage current specification (1 µA @ 50 V versus 2.5 µA @ 75 V) while maintaining all other electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the BAV99-7-F-31 across the specified parameter set. Selection among active alternatives is determined by packaging and supply requirements:

BAV99-7-F is the direct functional equivalent with active product status and highest inventory availability (269,400 pcs). This part is supplied in Cut Tape and Digi-Reel packaging formats, suitable for both manual and automated assembly operations.

BAV99-13-F provides identical electrical specifications with active status and moderate inventory (20,600 pcs), also available in Cut Tape and Digi-Reel packaging.

BAV99Q-7-F and BAV99Q-13-F are automotive-qualified variants (AEC-Q101) supplied in Tape & Reel format with active status. BAV99Q-7-F offers higher inventory (35,400 pcs) compared to BAV99Q-13-F (10,640 pcs). These variants are appropriate for applications requiring automotive qualification documentation.

MMBD7000-7-F is an alternative base product number with active status, supplied in Tape & Reel format. This part exhibits superior reverse leakage current performance (1 µA @ 50 V) and is suitable for applications with stringent leakage requirements. Inventory availability is limited (3,460 pcs).

All substitute parts comply with ROHS3 and maintain MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can BAV99-7-F directly replace BAV99-7-F-31 in existing designs?

A: Yes. The BAV99-7-F maintains identical electrical parameters (75 V reverse voltage, 300 mA per diode, 1.25 V forward voltage @ 150 mA, 4 ns reverse recovery time) and package configuration (SOT-23-3 surface mount). The primary difference is product status (active vs. obsolete) and packaging format availability.

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

A: Both parts are electrically identical with matching voltage, current, and thermal specifications. The suffix designations (-7-F vs. -13-F) indicate different manufacturing date codes or tape reel configurations. Selection between these parts is based on packaging format preference and inventory availability.

Q: When should BAV99Q variants be selected over standard BAV99 parts?

A: BAV99Q variants carry AEC-Q101 automotive qualification and are supplied in Tape & Reel format. These parts are appropriate for automotive applications or designs requiring formal automotive component certification. Electrical specifications remain identical to non-Q variants.

Q: How does MMBD7000-7-F differ from BAV99-7-F?

A: MMBD7000-7-F maintains all primary electrical specifications but features lower reverse leakage current (1 µA @ 50 V versus 2.5 µA @ 75 V). This alternative is suitable for applications with enhanced leakage performance requirements. Both parts use identical SOT-23-3 packaging and surface mount technology.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts comply with ROHS3 standards and maintain MSL 1 (Unlimited) moisture sensitivity classification, matching the original BAV99-7-F-31 specification.

Q: What packaging formats are available for these diode arrays?

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

Q: Is the operating temperature range consistent across all substitutes?

A: Yes. All substitute parts maintain the identical junction temperature operating range of -65°C to 150°C, ensuring thermal compatibility in existing circuit designs.
