BAV23CQ-7-F Equivalent & Substitute Parts

Part Overview

The BAV23CQ-7-F is a general-purpose diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode device in SOT-23-3 surface mount packaging. This component is rated for 250 V DC reverse voltage and 400 mA average rectified current per diode, with fast recovery characteristics suitable for automotive applications. The part maintains Active product status and carries AEC-Q101 automotive qualification.

Substitute parts are identified when equivalent or comparable diode array configurations become necessary due to inventory constraints, supply chain considerations, or design flexibility requirements while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV23CQ-7-F is determined by compatibility across the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-236-3, SC-59, SOT-23-3 (Surface Mount)
• Voltage - DC Reverse (Vr) (Max): 250 V or greater
• Current - Average Rectified (Io) (per Diode): 400 mA or greater
• Reverse Recovery Time (trr): 50 ns or less
• Current - Reverse Leakage @ Vr: 100 nA @ 200 V or less
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into three categories based on their relationship to the main part specifications:

Direct Manufacturer Substitute: Parts meeting all mandatory criteria with identical or superior electrical performance.

MFR Recommended Substitute: Parts meeting mandatory criteria with reduced current rating (200 mA vs. 400 mA) but maintaining voltage and recovery specifications.

Parametric Equivalent: Parts matching all electrical specifications and automotive qualifications with identical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

BAV23CQ-7-F (Primary Part): Recommended for applications requiring the full 400 mA current rating at 250 V reverse voltage with automotive AEC-Q101 qualification. Maintains active product status with established supply availability.

BAS21C-HF (Comchip Technology): Parametric equivalent offering identical electrical specifications (250 V, 400 mA, 50 ns recovery time) in the same SOT-23-3 package. Suitable for direct substitution in designs where the primary part becomes unavailable. Maintains RoHS3 compliance and MSL-1 rating. Note: Automotive grade and AEC-Q101 qualification status not specified in provided data.

BAS21C-AU_R1_000A1 (Panjit International Inc.): MFR recommended substitute with 250 V reverse voltage rating and AEC-Q101 automotive qualification. Current rating reduced to 200 mA per diode. Suitable for applications where current requirements do not exceed 200 mA. Maintains identical package, RoHS3 compliance, and MSL-1 rating.

BAV23C-HE3-08 (Vishay General Semiconductor): Direct manufacturer substitute with reduced specifications: 200 V reverse voltage and 200 mA current rating. Maintains AEC-Q101 qualification and identical SOT-23-3 package. Suitable only for applications with maximum voltage requirements of 200 V and current requirements not exceeding 200 mA.

Frequently Asked Questions (FAQ)

Q: Can BAV23C-HE3-08 replace BAV23CQ-7-F in all applications?

A: No. The BAV23C-HE3-08 has reduced voltage (200 V vs. 250 V) and current (200 mA vs. 400 mA) ratings. It is suitable only for applications with maximum voltage requirements of 200 V and current requirements not exceeding 200 mA per diode.

Q: What is the primary difference between BAS21C-AU_R1_000A1 and BAV23CQ-7-F?

A: The BAS21C-AU_R1_000A1 maintains the 250 V reverse voltage rating and AEC-Q101 qualification but has a reduced current rating of 200 mA per diode compared to 400 mA in the BAV23CQ-7-F. Both use identical SOT-23-3 packaging.

Q: Is BAS21C-HF a direct replacement for BAV23CQ-7-F?

A: BAS21C-HF matches all electrical specifications of BAV23CQ-7-F (250 V, 400 mA, 50 ns recovery time) and uses the same SOT-23-3 package. However, automotive grade and AEC-Q101 qualification status are not specified in the provided data. Verification of automotive compliance requirements is necessary before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (BAV23C-HE3-08, BAS21C-AU_R1_000A1, and BAS21C-HF) are ROHS3 compliant with MSL-1 (Unlimited) moisture sensitivity rating, matching the primary part.

Q: Can these parts be used interchangeably in PCB assembly?

A: All parts use identical SOT-23-3 surface mount packaging (TO-236-3, SC-59). PCB footprints are compatible. However, electrical parameter differences (voltage and current ratings) must be verified against circuit requirements before substitution.

Q: What is the operating temperature range for substitute parts?

A: BAV23CQ-7-F operates from -65°C to 150°C junction temperature. Substitute parts (BAV23C-HE3-08, BAS21C-AU_R1_000A1, BAS21C-HF) specify 150°C maximum junction temperature. The primary part offers extended low-temperature operation to -65°C.

Q: Which substitute part is recommended for automotive applications?

A: BAS21C-AU_R1_000A1 and BAV23C-HE3-08 both carry AEC-Q101 automotive qualification. BAS21C-HF does not specify automotive grade or AEC-Q101 qualification in the provided data. For automotive applications, BAS21C-AU_R1_000A1 is the recommended substitute, subject to current rating compatibility (200 mA maximum).
