Frequently Asked Questions (FAQ)

Q: Can BAV23C-7-F be used as a direct replacement for BAV23C-7?

A: Yes. BAV23C-7-F is a parametric equivalent with identical electrical specifications (200 V, 400 mA, 50 ns reverse recovery time) and the same SOT-23-3 package. The primary differences are packaging format (Cut Tape/Digi-Reel versus bulk) and product status (Active versus Discontinued). BAV23C-7-F is ROHS3 compliant.

Q: What is the difference between BAV23CQ-13-F and BAV23C-7-F?

A: Both parts are parametric equivalents with identical electrical specifications. BAV23CQ-13-F carries AEC-Q101 automotive qualification and is supplied in Tape & Reel format, while BAV23C-7-F is available in Cut Tape and Digi-Reel formats. Selection depends on packaging requirements and automotive qualification needs.

Q: Can I use BAV23C,215 or BAV23C-TP in place of BAV23C-7?

A: These parts are suitable substitutes if the application does not require the full 400 mA current capability. Both are rated for 225 mA average rectified current per diode, maintaining the 200 V voltage rating and 1.25 V forward voltage. Verify that circuit current requirements do not exceed 225 mA per diode.

Q: What is the advantage of BAV23CLT1G over BAV23C-7?

A: BAV23CLT1G provides enhanced voltage capability at 250 V DC reverse voltage compared to the 200 V rating of BAV23C-7, while maintaining the 400 mA current rating. The reverse recovery time is 150 ns versus 50 ns for BAV23C-7. This part is suitable for applications requiring higher voltage margins or where slightly slower recovery is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. The original BAV23C-7 is RoHS non-compliant. Selection of any substitute part addresses RoHS compliance requirements for new designs or production transitions.

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

A: All substitute parts are supplied in SOT-23-3 surface mount package. Packaging formats vary: BAV23C-7-F is available in Cut Tape and Digi-Reel; BAV23CQ-13-F, BAV23C,215, BAV23C-TP, BAV23CLT1G, and CMPD2004C are supplied in Tape & Reel format. Confirm packaging requirements with supplier specifications.

Q: Can CMPD2004C TR PBFREE replace BAV23C-7?

A: CMPD2004C TR PBFREE is a substitute option for applications with reduced current requirements (200 mA versus 400 mA). It provides enhanced voltage capability at 240 V and maintains the 50 ns reverse recovery time. Verify that circuit current requirements do not exceed 200 mA per diode and that the small signal technology classification is compatible with application requirements.

Q: What is the minimum voltage rating required for a substitute part?

A: The minimum voltage rating for a substitute part is 200 V DC reverse voltage to match the BAV23C-7 specification. Parts with higher voltage ratings (BAV23CLT1G at 250 V, CMPD2004C at 240 V) are acceptable and provide additional voltage margin.

Q: What is the minimum current rating required for a substitute part?

A: For direct replacement in applications requiring full 400 mA capability, the substitute part must be rated for 400 mA average rectified current per diode. BAV23C-7-F and BAV23CQ-13-F meet this requirement. Parts with 225 mA or 200 mA ratings are suitable only for applications with reduced current requirements.
