BAV3004W-7 Equivalent & Substitute Parts

Part Overview

The BAV3004W-7 is a general-purpose rectifier diode rated for 300 V DC reverse voltage and 225 mA average rectified current in a surface mount SOD-123 package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts for ongoing design support and procurement. Equivalent diodes must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV3004W-7 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 300 V
• Current - Average Rectified (Io): 225 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 240 V
• Capacitance @ Vr, F: 5 pF @ 0 V, 1 MHz
• Technology: Standard
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Package / Case: SOD-123
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 150°C

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the BAV3004W-7 in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

BAV3004W-7-F (Diodes Incorporated)

The BAV3004W-7-F is a parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications. This part carries ROHS3 compliance status, whereas the original BAV3004W-7 is RoHS non-compliant. The BAV3004W-7-F is classified as obsolete and available in Cut Tape (CT) & Digi-Reel® packaging with significantly higher inventory availability (36,300 units). This substitute is suitable for applications where RoHS3 compliance is required or preferred.

CDSW3004-HF (Comchip Technology)

The CDSW3004-HF is a parametric equivalent manufactured by Comchip Technology with identical electrical specifications and SOD-123 package compatibility. This part maintains active product status and carries ROHS3 compliance certification. The CDSW3004-HF is available in Tape & Reel (TR) packaging with high inventory availability (34,325 units). This substitute is suitable for new designs and applications requiring active product support and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can BAV3004W-7-F be used as a direct replacement for BAV3004W-7?

A: Yes. The BAV3004W-7-F is a parametric equivalent with identical electrical characteristics (300 V reverse voltage, 225 mA average rectified current, 1.25 V forward voltage at 200 mA, 50 ns reverse recovery time) and mechanical compatibility (SOD-123 surface mount package, -65°C to 150°C operating temperature range). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and RoHS compliance status.

Q: Can CDSW3004-HF be used as a direct replacement for BAV3004W-7?

A: Yes. The CDSW3004-HF is a parametric equivalent with identical electrical characteristics and mechanical compatibility. The manufacturer differs (Comchip Technology versus Diodes Incorporated), but all critical electrical parameters and the SOD-123 package specification are equivalent. The CDSW3004-HF maintains active product status.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by equivalence across: Voltage - DC Reverse (Vr) (Max) of 300 V, Current - Average Rectified (Io) of 225 mA, Voltage - Forward (Vf) (Max) of 1.25 V @ 200 mA, Reverse Recovery Time (trr) of 50 ns, Current - Reverse Leakage @ Vr of 100 nA @ 240 V, and Capacitance @ Vr, F of 5 pF @ 0 V, 1 MHz. All substitute parts meet these specifications.

Q: Are there packaging differences between the substitute parts?

A: Yes. The BAV3004W-7 is supplied in Tape & Reel (TR) packaging. The BAV3004W-7-F is supplied in Cut Tape (CT) & Digi-Reel® packaging. The CDSW3004-HF is supplied in Tape & Reel (TR) packaging. All three parts use the SOD-123 surface mount package and are compatible with standard pick-and-place assembly equipment.

Q: What is the difference in RoHS compliance status?

A: The BAV3004W-7 is RoHS non-compliant. Both BAV3004W-7-F and CDSW3004-HF are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, either substitute part is appropriate.

Q: Which substitute part has the best availability?

A: The BAV3004W-7-F has the highest inventory availability at 36,300 units. The CDSW3004-HF has 34,325 units in stock. Both parts have substantially higher availability than the original BAV3004W-7 (903 units).

Q: What is the product status of each part?

A: The BAV3004W-7 is discontinued at DiGi Electronics. The BAV3004W-7-F is classified as obsolete. The CDSW3004-HF maintains active product status. For new designs requiring long-term support, the CDSW3004-HF is the recommended selection.
