BAV16WS-7 Equivalent & Substitute Parts

Part Overview

The BAV16WS-7 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 75 V DC reverse voltage and 150 mA average rectified current in a surface mount SOD-323 package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production needs. Equivalent parts maintain identical electrical specifications, while substitute parts provide functional alternatives with modified parameters suitable for the same application space.

Substitute Part Grouping Explanation

Substitution of the BAV16WS-7 is determined by the following critical parameters: reverse voltage rating (75 V minimum), average rectified current capacity (150 mA minimum), forward voltage drop characteristics, reverse recovery time, package type (SOD-323), and mounting configuration (surface mount). Parts are grouped into three categories:

Parametric Equivalents (Identical Specifications): Parts maintaining all electrical specifications of the BAV16WS-7, including 75 V reverse voltage, 150 mA current rating, 1.25 V forward voltage at 150 mA, 4 ns reverse recovery time, and 2 pF capacitance. These parts differ only in product status, RoHS compliance, or packaging format (cut tape versus tape and reel).

Manufacturer Recommended Alternatives (Vishay and Comchip): Parts with 75 V reverse voltage and 150 mA current rating but with modified forward voltage specifications (1.2 V @ 100 mA instead of 1.25 V @ 150 mA) or different reverse leakage characteristics. These maintain functional compatibility within the 75 V / 150 mA operating envelope.

Higher-Rated Substitutes (Micro Commercial Co and Nexperia): Parts with increased current capacity (250 mA) or voltage rating (100 V), providing design margin for applications requiring enhanced performance headroom while maintaining SOD-323 packaging and surface mount compatibility.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents): The parts 1N4148WS-7-F, 1N4148WSQ-13-F, and BAV16WS-7-F are parametric equivalents of the BAV16WS-7, maintaining identical electrical specifications across all critical parameters. All three are manufactured by Diodes Incorporated and carry ROHS3 compliance. Selection between these three depends on packaging format: 1N4148WS-7-F and BAV16WS-7-F are supplied in cut tape format, while 1N4148WSQ-13-F is supplied in tape and reel format. The 1N4148WSQ-13-F carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components.

Vishay Alternatives: The 1N4148WS-E3-18 and 1N4148WS-HE3-08 from Vishay General Semiconductor maintain the 75 V / 150 mA specification envelope with forward voltage specified at 1.2 V @ 100 mA (versus 1.25 V @ 150 mA on the original part). These parts are suitable for applications where the lower forward voltage specification provides design margin. The 1N4148WS-HE3-08 carries AEC-Q101 automotive qualification and is supplied in tape and reel format.

Higher-Rated Alternatives: The 1N4448WX-TP (Micro Commercial Co) and BAS316 variants (Nexperia) provide increased current capacity (250 mA) or voltage rating (100 V), suitable for applications requiring enhanced performance margin. The BAS316 variants carry AEC-Q101 automotive qualification. These parts are appropriate when design requirements exceed the original 75 V / 150 mA specification.

Comchip Alternative: The CDSF4148 maintains 75 V / 150 mA specifications but uses a 1005 (2512 Metric) package variant of SOD-323F. This part is suitable only when the 1005 package footprint is compatible with the application design.

All recommended substitutes carry ROHS3 compliance and are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use 1N4148WS-7-F as a direct replacement for BAV16WS-7?

A: Yes. The 1N4148WS-7-F is a parametric equivalent with identical electrical specifications: 75 V reverse voltage, 150 mA current rating, 1.25 V forward voltage at 150 mA, and 4 ns reverse recovery time. Both use SOD-323 surface mount packaging. The primary difference is product status (1N4148WS-7-F is active and ROHS3 compliant, while BAV16WS-7 is discontinued and non-compliant).

Q: What is the difference between 1N4148WS-7-F and 1N4148WSQ-13-F?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format: 1N4148WS-7-F is supplied in cut tape format, while 1N4148WSQ-13-F is supplied in tape and reel format. Additionally, 1N4148WSQ-13-F carries AEC-Q101 automotive qualification.

Q: Can I use a part with higher current rating, such as 1N4448WX-TP (250 mA)?

A: Yes. The 1N4448WX-TP maintains the 75 V reverse voltage specification and can handle 250 mA average rectified current, exceeding the original 150 mA requirement. This part is suitable for applications where increased current capacity provides design margin. Electrical characteristics remain compatible with the original application.

Q: What is the difference between Vishay 1N4148WS-E3-18 and Diodes 1N4148WS-7-F?

A: Both parts maintain 75 V / 150 mA specifications and 4 ns reverse recovery time. The Vishay part specifies forward voltage at 1.2 V @ 100 mA, while the Diodes part specifies 1.25 V @ 150 mA. The Vishay specification represents a lower forward voltage measurement point. Both are ROHS3 compliant and suitable for direct substitution.

Q: Can I use BAS316,115 or BAS316,135 as substitutes?

A: Yes. These Nexperia parts maintain 75 V reverse voltage (actually rated to 100 V) and support 250 mA current, exceeding the original 150 mA requirement. Both carry AEC-Q101 automotive qualification. These parts are suitable when higher voltage or current margin is required. The two part numbers differ only in packaging or supplier designation.

Q: Does the CDSF4148 from Comchip work as a substitute?

A: The CDSF4148 maintains 75 V / 150 mA electrical specifications but uses a 1005 (2512 Metric) package variant. This part is suitable only if your PCB design accommodates the 1005 package footprint. The SOD-323 standard package is not compatible with 1005 footprints.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts carry ROHS3 compliance. The original BAV16WS-7 is RoHS non-compliant. If RoHS compliance is a design requirement, select from the active, ROHS3-compliant alternatives.

Q: Which substitute part has the best availability?

A: The 1N4148WS-E3-18 from Vishay has the highest inventory (720,400 pcs), followed by 1N4148WS-7-F from Diodes (1,000,300 pcs). Both are suitable for immediate procurement.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all selected parts meet the application's electrical requirements. All parametric equivalents and recommended substitutes maintain compatibility within the 75 V / 150 mA operating envelope and SOD-323 surface mount package. Verify forward voltage and reverse leakage specifications against your circuit design requirements.
