BAV99T-7 Equivalent & Substitute Parts

Part Overview

The BAV99T-7 is a general-purpose diode array manufactured by Diodes Incorporated, configured as 1 pair series connection in a surface mount SOT-523 package. This component is rated for 85 V DC reverse voltage and 75 mA average rectified current per diode, with a maximum forward voltage of 1 V at 50 mA. The BAV99T-7 is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production continuity. Alternative components must maintain electrical compatibility while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV99T-7 are classified into two categories based on electrical and mechanical compatibility:

Category 1: Direct Parametric Equivalents (SOT-523 Package)

These parts maintain identical electrical specifications and package form factor:

• Voltage - DC Reverse (Vr) (Max): 85 V
• Current - Average Rectified (Io) (per Diode): 75 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 50 mA
• Reverse Recovery Time (trr): 4 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 75 V
• Package / Case: SOT-523
• Diode Configuration: 1 Pair Series Connection

Category 2: Manufacturer Recommended Alternatives (Different Package)

These parts are from the same BAV99 series but utilize a different package form factor (TO-236-3/SOT-23-3) with enhanced electrical ratings:

• Voltage - DC Reverse (Vr) (Max): 100 V (higher rating)
• Current - Average Rectified (Io) (per Diode): 215 mA (DC) (higher rating)
• Diode Configuration: 1 Pair Series Connection
• Package / Case: TO-236-3, SC-59, SOT-23-3

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Electrical Ratings):

BAV99T-7-F is the primary direct substitute. This part is manufactured by Diodes Incorporated and maintains identical electrical specifications and SOT-523 package form factor. BAV99T-7-F is currently active with ROHS3 compliance, addressing the RoHS non-compliance status of the discontinued BAV99T-7. Packaging is available in both Cut Tape and Digi-Reel formats.

BAV99TQ-13-F provides an alternative direct equivalent from Diodes Incorporated with identical electrical parameters and SOT-523 packaging. This variant includes AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging. Selection of this part is appropriate for automotive applications requiring qualification documentation.

BAV99T-TP is a direct parametric equivalent manufactured by Micro Commercial Co in SOT-523 package with Tape & Reel packaging. This part is ROHS3 compliant and active. The operating temperature range is -55°C to 150°C, which is narrower than the BAV99T-7 specification of -65°C to 150°C.

For Enhanced Performance Applications:

BAV99,215 and BAV99,235 are manufacturer-recommended alternatives from Nexperia USA Inc. within the BAV99 series. These parts feature enhanced electrical ratings (100 V reverse voltage, 215 mA average rectified current) and utilize the TO-236-3/SOT-23-3 package form factor. Both parts are AEC-Q101 qualified and ROHS3 compliant. Selection of these parts is appropriate when higher current capacity or voltage margin is required, provided that PCB layout and assembly processes accommodate the different package geometry.

Frequently Asked Questions (FAQ)

Q: Can BAV99T-7-F be used as a direct replacement for BAV99T-7?

A: Yes. BAV99T-7-F maintains identical electrical specifications (85 V reverse voltage, 75 mA average rectified current, 1 V forward voltage at 50 mA) and uses the same SOT-523 package. Both parts are configured as 1 pair series connection diode arrays. The primary difference is product status: BAV99T-7-F is active and ROHS3 compliant, while BAV99T-7 is discontinued and RoHS non-compliant.

Q: What is the difference between BAV99T-7-F and BAV99TQ-13-F?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical specifications and SOT-523 packaging. The key difference is that BAV99TQ-13-F includes AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging, while BAV99T-7-F is available in both Cut Tape and Digi-Reel formats without automotive qualification documentation.

Q: Can BAV99,215 or BAV99,235 be used in place of BAV99T-7?

A: BAV99,215 and BAV99,235 are electrically compatible alternatives with enhanced ratings (100 V reverse voltage versus 85 V, and 215 mA average rectified current versus 75 mA). However, these parts use the TO-236-3/SOT-23-3 package instead of SOT-523. PCB layout modifications are required to accommodate the different package footprint. These parts are suitable for applications requiring higher current capacity or voltage margin.

Q: What is the difference between BAV99T-TP and BAV99T-7-F?

A: Both parts are direct parametric equivalents with identical electrical specifications and SOT-523 packaging. BAV99T-TP is manufactured by Micro Commercial Co and supplied in Tape & Reel format, while BAV99T-7-F is manufactured by Diodes Incorporated and available in both Cut Tape and Digi-Reel formats. The operating temperature range of BAV99T-TP is -55°C to 150°C, which is narrower than BAV99T-7-F at -65°C to 150°C.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. The original BAV99T-7 is RoHS non-compliant. Selection of any substitute part addresses RoHS compliance requirements for new designs and production.

Q: Which substitute part has the highest inventory availability?

A: BAV99,235 has the highest inventory availability with 644,803 pieces in stock. BAV99,215 has 36,300 pieces, BAV99T-7-F has 31,939 pieces, BAV99T-TP has 12,492 pieces, and BAV99TQ-13-F has 8,619 pieces.

Q: Do any substitute parts have automotive qualification?

A: Yes. BAV99TQ-13-F, BAV99,215, and BAV99,235 all carry AEC-Q101 automotive qualification. These parts are suitable for automotive applications requiring qualification documentation.

Q: What packaging options are available for direct SOT-523 replacements?

A: BAV99T-7-F is available in Cut Tape and Digi-Reel packaging. BAV99TQ-13-F and BAV99T-TP are supplied in Tape & Reel packaging. Selection depends on assembly process requirements and volume considerations.
