BAV99S/ZLX Equivalent & Substitute Parts

Part Overview

The BAV99S/ZLX is a general-purpose diode array manufactured by Nexperia USA Inc., configured as a 2-pair series connection rated for 100 V DC reverse voltage and 200 mA average rectified current per diode. The device is packaged in a 6-TSSOP (SC-88, SOT-363) surface mount package and is classified as obsolete. Due to its obsolete product status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV99S/ZLX is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Diode configuration (2 pair series connection)
• Maximum DC reverse voltage (100 V)
• Average rectified current per diode (200 mA)
• Forward voltage characteristics (1.25 V @ 150 mA)
• Reverse recovery time (4 ns)
• Reverse leakage current (500 nA @ 80 V)
• Maximum junction operating temperature (150°C)
• Surface mount package type (6-TSSOP, SC-88, SOT-363)
• RoHS3 compliance and MSL rating (1)

All identified substitute parts meet these electrical and mechanical requirements. Substitute parts are grouped into two categories: Nexperia USA Inc. variants (BAV99S,115 and BAV99S,135) and the Diodes Incorporated equivalent (BAV99HDWQ-13). The Nexperia variants are active products with automotive-grade qualification (AEC-Q101), while the Diodes Incorporated part is also active with automotive qualification and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (BAV99S,115, BAV99S,135, and BAV99HDWQ-13) are electrically and mechanically equivalent to the BAV99S/ZLX and are suitable for direct replacement in applications requiring the specified electrical characteristics and package form factor.

Nexperia USA Inc. Variants (BAV99S,115 and BAV99S,135): Both parts are active products from the same manufacturer as the original part, ensuring design continuity and supply chain consistency. Both carry automotive-grade qualification (AEC-Q101) and are available in high inventory quantities (693,459 pcs and 36,150 pcs respectively). These parts are recommended for applications requiring Nexperia sourcing or where automotive qualification is a design requirement.

Diodes Incorporated Equivalent (BAV99HDWQ-13): This part is an active product from an alternative manufacturer and meets all electrical and mechanical specifications. It carries automotive-grade qualification (AEC-Q101) and provides an extended operating temperature range (-65°C to 150°C) compared to the main part specification. This part is available in substantial inventory (111,887 pcs) and is suitable for applications requiring cross-manufacturer sourcing or extended temperature performance.

All substitute parts maintain RoHS3 compliance and MSL rating 1 (unlimited moisture sensitivity), ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can BAV99S,115 or BAV99S,135 be used as direct replacements for BAV99S/ZLX?

A: Yes. Both parts are parametrically equivalent to the BAV99S/ZLX across all critical electrical parameters including reverse voltage (100 V), rectified current (200 mA per diode), forward voltage (1.25 V @ 150 mA), and reverse recovery time (4 ns). Both are packaged in the identical 6-TSSOP (SC-88, SOT-363) surface mount package and are pin-compatible.

Q: What is the difference between BAV99S,115 and BAV99S,135?

A: Both parts are electrically and mechanically identical. The differences are in packaging format (both are Cut Tape and Digi-Reel) and inventory availability. BAV99S,115 has higher inventory (693,459 pcs) compared to BAV99S,135 (36,150 pcs). Selection between these two should be based on procurement quantity requirements and lead time considerations.

Q: Is BAV99HDWQ-13 compatible with the BAV99S/ZLX?

A: Yes. BAV99HDWQ-13 is electrically and mechanically equivalent to BAV99S/ZLX. It meets all specified electrical parameters and is packaged in the same 6-TSSOP (SC-88, SOT-363) surface mount configuration. The primary difference is the manufacturer (Diodes Incorporated) and an extended operating temperature range (-65°C to 150°C). This part is suitable for applications requiring cross-manufacturer sourcing.

Q: Are all substitute parts automotive-qualified?

A: Yes. All three substitute parts (BAV99S,115, BAV99S,135, and BAV99HDWQ-13) carry automotive-grade qualification (AEC-Q101), making them suitable for automotive and industrial applications requiring this certification.

Q: What is the significance of the reverse leakage current specification difference in BAV99HDWQ-13?

A: The BAV99HDWQ-13 specifies reverse leakage current as 500 nA @ 8 V, while the main part and other substitutes specify 500 nA @ 80 V. Both specifications indicate the same leakage current magnitude; the difference is the voltage at which the measurement is taken. This does not affect functional equivalence for the specified application parameters.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (BAV99S,115, BAV99S,135, and BAV99HDWQ-13) are RoHS3 compliant with MSL rating 1 (unlimited), ensuring compatibility with standard manufacturing processes and storage requirements.

Q: What packaging formats are available for the substitute parts?

A: BAV99S,115 and BAV99S,135 are available in Cut Tape (CT) and Digi-Reel packaging formats. BAV99HDWQ-13 is available in Tape & Reel (TR) format. Selection should be based on assembly process requirements and procurement volume.
