Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV70_L99Z are classified based on electrical and mechanical parameter compatibility. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 70 V
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 6 ns
• Operating Temperature - Junction: 150°C

Mechanical Parameters (Must Match or Exceed):

• Current - Average Rectified (Io) (per Diode): 200 mA minimum
• Mounting Type: Surface Mount
• Package / Case: SOT-563, SOT-666, or compatible surface mount packages

Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts are identified as either parametric equivalents (identical electrical and mechanical specifications with active product status) or similar alternatives (same base series with enhanced or modified specifications).

Engineering Selection Recommendations

NSVBAV70DXV6T1G (Parametric Equivalent - Recommended Primary Substitute)

The NSVBAV70DXV6T1G is a parametric equivalent manufactured by onsemi with identical electrical specifications and package compatibility to the BAV70_L99Z. This part maintains all critical parameters including 70 V reverse voltage rating, 200 mA average rectified current, 1.25 V forward voltage at 150 mA, and 6 ns reverse recovery time. The NSVBAV70DXV6T1G holds active product status and is ROHS3 compliant, providing long-term supply assurance. Pin-for-pin compatibility and identical SOT-563 packaging enable direct substitution without circuit redesign.

BAV70-E3-08 (Similar Alternative - Secondary Option)

The BAV70-E3-08 manufactured by Vishay General Semiconductor is a similar alternative within the BAV70 series. This part shares the same 70 V reverse voltage rating, 1.25 V forward voltage at 150 mA, and 6 ns reverse recovery time. The BAV70-E3-08 provides enhanced current capability at 250 mA (DC) average rectified current, exceeding the 200 mA requirement of the BAV70_L99Z. However, the BAV70-E3-08 is packaged in SOT-23-3 (TO-236-3, SC-59) rather than SOT-563, requiring PCB layout modification. The reverse leakage current specification differs at 50 µA @ 70 V compared to 5 µA @ 70 V for the main part. This alternative is suitable for applications where package footprint change is acceptable and higher current margin is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the NSVBAV70DXV6T1G be used as a direct replacement for the BAV70_L99Z?

A: Yes. The NSVBAV70DXV6T1G is a parametric equivalent with identical electrical specifications, forward voltage characteristics, reverse recovery time, and SOT-563 package compatibility. No circuit modifications are required.

Q: What is the primary difference between the NSVBAV70DXV6T1G and BAV70-E3-08?

A: The NSVBAV70DXV6T1G maintains identical specifications to the BAV70_L99Z with active product status. The BAV70-E3-08 offers higher current rating (250 mA versus 200 mA) but uses a different package (SOT-23-3 versus SOT-563) and has higher reverse leakage current (50 µA versus 5 µA at 70 V).

Q: Is package compatibility critical when selecting a substitute?

A: Package compatibility depends on application requirements. The NSVBAV70DXV6T1G uses the same SOT-563 package as the BAV70_L99Z, enabling direct PCB substitution. The BAV70-E3-08 uses SOT-23-3 packaging, requiring PCB layout changes and potential circuit board redesign.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the NSVBAV70DXV6T1G and BAV70-E3-08 are ROHS3 compliant, meeting environmental and regulatory requirements for new designs.

Q: What is the significance of the reverse leakage current difference between the BAV70_L99Z and BAV70-E3-08?

A: The BAV70_L99Z specifies 5 µA @ 70 V reverse leakage, while the BAV70-E3-08 specifies 50 µA @ 70 V. This tenfold difference may impact applications with stringent leakage requirements. The NSVBAV70DXV6T1G maintains the 5 µA specification, matching the original part.

Q: Can the BAV70-E3-08 be used in applications requiring the exact 200 mA current rating?

A: Yes. The BAV70-E3-08 is rated for 250 mA (DC) average rectified current, which exceeds the 200 mA requirement. Applications designed for 200 mA operation operate within the BAV70-E3-08 specification margin.

Q: What is the product status significance for long-term supply?

A: The BAV70_L99Z is classified as obsolete, indicating discontinued production. The NSVBAV70DXV6T1G and BAV70-E3-08 both hold active product status, ensuring continued availability and supply chain support for future production requirements.
