Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV99 is determined by strict electrical and mechanical compatibility criteria. All substitute parts must satisfy the following requirements:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Series Connection
• Current Rating: 200 mA (DC) per diode minimum
• Package / Case: TO-236-3, SC-59, SOT-23-3 (identical physical form factor)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 80 V
• Operating Temperature - Junction: Equal to or greater than 150°C
• Forward voltage and reverse recovery time may vary within the small signal diode classification

The identified substitute parts meet all mandatory compatibility parameters and exceed or match the electrical performance specifications of the BAV99.

Parameter Comparison

Engineering Selection Recommendations

MMBD7000LT1G (onsemi) is the primary substitute for the BAV99. This part maintains electrical performance parity with the original component while offering an increased reverse voltage rating of 100 V. The MMBD7000LT1G is classified as Active product status, ensuring long-term availability and supply chain continuity. The device is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

BAS101S,215 (Nexperia USA Inc.) is an alternative substitute suitable for applications requiring higher reverse voltage capability. This part is rated for 300 V maximum reverse voltage and is qualified to AEC-Q100 automotive standards. The BAS101S,215 is classified as Active product status with RoHS3 Compliance and REACH Unaffected status. The extended reverse recovery time of 50 ns should be evaluated against application switching frequency requirements.

Both substitute parts are available in identical Surface Mount TO-236-3 (SOT-23-3) packages and maintain the same 200 mA current rating and 1 Pair Series Connection configuration as the BAV99. Selection between these substitutes depends on application voltage requirements and switching performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the MMBD7000LT1G directly replace the BAV99 in existing designs?

A: Yes. The MMBD7000LT1G maintains identical package geometry (TO-236-3, SOT-23-3), diode configuration (1 Pair Series Connection), and current rating (200 mA per diode). The increased reverse voltage rating of 100 V exceeds the BAV99 specification of 80 V, providing design margin. Pin-to-pin compatibility is confirmed.

Q: What is the primary difference between the MMBD7000LT1G and BAS101S,215 substitutes?

A: The primary difference is reverse voltage rating. The MMBD7000LT1G is rated for 100 V maximum reverse voltage, while the BAS101S,215 is rated for 300 V. The BAS101S,215 also exhibits a longer reverse recovery time of 50 ns compared to 4 ns for the MMBD7000LT1G. Application voltage and switching frequency requirements determine the appropriate selection.

Q: Are both substitute parts available in the same packaging format as the BAV99?

A: Yes. Both the MMBD7000LT1G and BAS101S,215 are supplied in Surface Mount TO-236-3 (SOT-23-3) packages, identical to the BAV99. Both parts have Moisture Sensitivity Level 1 (Unlimited), matching the original component specification.

Q: What is the product status of the substitute parts?

A: Both substitute parts are classified as Active. The MMBD7000LT1G is manufactured by onsemi and the BAS101S,215 is manufactured by Nexperia USA Inc. Active product status ensures ongoing availability and supply chain support.

Q: Do the substitute parts meet current environmental compliance standards?

A: Yes. The MMBD7000LT1G is RoHS3 Compliant and REACH Unaffected. The BAS101S,215 is RoHS3 Compliant, REACH Unaffected, and qualified to AEC-Q100 automotive standards. Both parts meet current regulatory requirements.

Q: How do forward voltage characteristics compare between the BAV99 and substitute parts?

A: The BAV99 specifies maximum forward voltage of 1.25 V at 150 mA. The MMBD7000LT1G specifies 1.1 V at 100 mA, and the BAS101S,215 specifies 1.1 V at 100 mA. Both substitutes exhibit lower forward voltage characteristics, which may reduce power dissipation in rectification applications.

Q: What is the significance of reverse recovery time differences?

A: The BAV99 specifies 3 ns reverse recovery time, the MMBD7000LT1G specifies 4 ns, and the BAS101S,215 specifies 50 ns. Reverse recovery time affects switching performance in high-frequency applications. Applications operating at frequencies where reverse recovery time is critical should select the MMBD7000LT1G for performance closest to the original BAV99.
