BAV99TA Equivalent & Substitute Parts

Part Overview

The BAV99TA is a general-purpose diode array manufactured by Diodes Incorporated, configured as 1 pair series connection in a surface mount SOT-23-3 package. This component is rated for 75 V DC reverse voltage and 300 mA average rectified current per diode, with fast recovery characteristics suitable for switching applications. The BAV99TA is currently listed as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the BAV99TA is determined by the following critical parameters: diode configuration (1 pair series connection), package type (SOT-23-3), mounting method (surface mount), and electrical ratings (reverse voltage, forward current, and recovery characteristics). Parts are grouped into two categories:

Parametric Equivalents (Diodes Incorporated): Parts BAV99-13-F, BAV99-7-F, BAV99Q-13-F, BAV99Q-7-F, and MMBD7000-7-F maintain identical or superior electrical specifications to the BAV99TA while offering active product status and RoHS3 compliance. These parts share the same diode configuration, package, and core electrical parameters.

Manufacturer Recommended Alternatives: Parts from Nexperia USA Inc. (BAV99,215 and BAV99,235), Micro Commercial Co (BAV99-TP), and onsemi (BAV99LT1G and BAV99LT3G) provide functional equivalence with variations in reverse voltage rating (70–100 V), average rectified current (200–215 mA), or reverse recovery time (6 ns). These alternatives are suitable where the application permits higher voltage ratings or lower current ratings than the original BAV99TA specification.

Engineering Selection Recommendations

Direct Parametric Equivalents: BAV99-13-F, BAV99-7-F, BAV99Q-13-F, BAV99Q-7-F, and MMBD7000-7-F from Diodes Incorporated are direct replacements for the BAV99TA. These parts maintain identical electrical specifications (75 V reverse voltage, 300 mA average rectified current, 4 ns reverse recovery time) and the same SOT-23-3 package. All are active products with RoHS3 compliance, addressing the obsolescence and regulatory status of the original part. BAV99-7-F offers the highest inventory availability (269,400 units) among Diodes Incorporated equivalents.

Higher Voltage Rating Alternatives: BAV99,215, BAV99,235 (Nexperia USA Inc.), BAV99LT1G, and BAV99LT3G (onsemi) provide 100 V reverse voltage rating with 215 mA average rectified current. These parts are suitable for applications where the original 75 V specification provides insufficient margin or where higher voltage tolerance is required. Both Nexperia and onsemi parts carry AEC-Q101 automotive qualification where specified.

Lower Rating Alternative: BAV99-TP from Micro Commercial Co operates at 70 V reverse voltage and 200 mA average rectified current with 6 ns reverse recovery time. This part is applicable only where the application requirements do not exceed these reduced ratings.

All recommended substitutes maintain the SOT-23-3 surface mount package, 1 pair series connection configuration, and -65°C to 150°C operating temperature range of the original BAV99TA.

Frequently Asked Questions (FAQ)

Q: Can BAV99-7-F directly replace BAV99TA in existing designs?

A: Yes. BAV99-7-F is a parametric equivalent with identical reverse voltage (75 V), average rectified current (300 mA), forward voltage (1.25 V @ 150 mA), and reverse recovery time (4 ns). Both use the SOT-23-3 package. The primary difference is product status: BAV99-7-F is active with RoHS3 compliance, while BAV99TA is obsolete and non-compliant.

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

A: Both parts share identical electrical specifications and the SOT-23-3 package. The primary distinction is packaging format: BAV99-7-F is supplied in Cut Tape (CT) & Digi-Reel format, while BAV99Q-7-F is supplied in Tape & Reel (TR) format. BAV99Q-7-F also carries AEC-Q101 automotive qualification. Selection depends on procurement and assembly requirements.

Q: Can I use BAV99LT1G as a substitute if my application requires 300 mA?

A: BAV99LT1G is rated for 215 mA average rectified current, which is below the BAV99TA specification of 300 mA. This part is not suitable for applications requiring the full 300 mA rating. Use BAV99-7-F, BAV99-13-F, or other Diodes Incorporated equivalents that maintain the 300 mA specification.

Q: What is the advantage of using MMBD7000-7-F over BAV99-7-F?

A: MMBD7000-7-F maintains identical electrical specifications to BAV99-7-F (75 V, 300 mA, 4 ns recovery time) and the same SOT-23-3 package. Both are active products with RoHS3 compliance. The selection between them depends on availability, cost, and supply chain considerations. MMBD7000-7-F has lower inventory (3,460 units) compared to BAV99-7-F (269,400 units).

Q: Are Nexperia BAV99,215 and BAV99,235 interchangeable?

A: Yes. Both parts are electrically identical with 100 V reverse voltage, 215 mA average rectified current, 4 ns reverse recovery time, and SOT-23-3 package. Both carry AEC-Q101 automotive qualification and RoHS3 compliance. Selection depends on packaging format and inventory availability. BAV99,235 has significantly higher inventory (644,803 units) compared to BAV99,215 (36,300 units).

Q: Why does BAV99-TP have different electrical ratings than other substitutes?

A: BAV99-TP from Micro Commercial Co is rated for 70 V reverse voltage and 200 mA average rectified current, both lower than the BAV99TA specification. This part is suitable only for applications where these reduced ratings meet the design requirements. For applications requiring the full BAV99TA specifications, use parametric equivalents from Diodes Incorporated.

Q: What does RoHS3 compliance mean for my design?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. The BAV99TA is RoHS non-compliant, while all recommended substitutes are RoHS3 compliant. If your design or market requires RoHS compliance, select from the active substitute parts listed.

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

A: All parametric equivalents (BAV99-7-F, BAV99-13-F, BAV99Q-7-F, BAV99Q-13-F, MMBD7000-7-F) maintain identical electrical specifications and the same SOT-23-3 package, allowing interchangeability within a single design. However, mixing parts with different electrical ratings (such as combining 75 V and 100 V variants) requires design verification to ensure compatibility with application requirements.
