BAV70 Equivalent & Substitute Parts

Part Overview

The BAV70 is a general-purpose diode array in a 1 Pair Common Cathode configuration, manufactured by Panasonic Electronic Components. This surface mount device operates at 80 V DC reverse voltage with 200 mA average rectified current per diode. The BAV70 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across diode configuration, mounting type, package format, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV70 is determined by strict equivalence across the following parameters:

Configuration Match: The substitute part must maintain 1 Pair Common Cathode diode configuration to ensure pin-level compatibility and functional operation within existing circuit topologies.

Mounting and Package Match: Surface mount technology with TO-236-3, SC-59, SOT-23-3 package format is mandatory for mechanical and electrical interconnection compatibility.

Electrical Performance Envelope: The substitute part must support the required current rating of 200 mA (DC) average rectified current per diode. The forward voltage drop at 150 mA must not exceed 1.25 V to maintain circuit performance. The reverse voltage rating must equal or exceed the 80 V specification of the original part.

Speed Classification: Small signal diode classification with any speed rating satisfies the original specification.

The BAV70LT1G manufactured by onsemi meets all substitution criteria. This part is active in production status, offers enhanced reverse voltage rating (100 V), maintains identical current and forward voltage specifications, and is available in the same package format.

Engineering Selection Recommendations

For New Designs: The BAV70LT1G is the appropriate selection. This part is active in production status, ensuring long-term availability and supply chain stability. The onsemi BAV70LT1G provides enhanced reverse voltage rating (100 V versus 80 V), offering additional design margin without compromising any electrical or mechanical specifications. RoHS3 compliance and REACH unaffected status support regulatory requirements for modern manufacturing environments.

For Existing Production: Direct substitution of BAV70 with BAV70LT1G is permissible. Identical package format, diode configuration, current rating, and forward voltage characteristics ensure functional equivalence. The higher reverse voltage rating of the substitute part does not introduce incompatibility; circuits designed for 80 V operation function correctly with a 100 V rated component.

Compliance Considerations: Both parts share identical ECCN (EAR99) and HTSUS classifications. The BAV70LT1G provides additional compliance documentation through RoHS3 certification and REACH status confirmation, supporting supply chain transparency and regulatory compliance verification.

Frequently Asked Questions (FAQ)

Q: Can BAV70LT1G replace BAV70 in existing circuit designs?

A: Yes. The BAV70LT1G maintains identical diode configuration (1 Pair Common Cathode), current rating (200 mA DC per diode), forward voltage drop (1.25 V @ 150 mA), and package format (SOT-23-3). The enhanced reverse voltage rating (100 V versus 80 V) does not create incompatibility; circuits designed for 80 V operation function correctly with the higher-rated substitute.

Q: Are the package dimensions identical between BAV70 and BAV70LT1G?

A: Yes. Both parts use the TO-236-3, SC-59, SOT-23-3 package format. Mechanical compatibility is confirmed for PCB layout, footprint, and assembly processes.

Q: What is the primary reason for substituting BAV70?

A: The BAV70 is classified as obsolete. The BAV70LT1G is an active production part from onsemi, ensuring continued availability, supply chain reliability, and access to current manufacturing documentation and certifications.

Q: Do the parts differ in reverse leakage current?

A: Yes. The BAV70 specifies 100 nA @ 80 V reverse leakage, while the BAV70LT1G specifies 2.5 µA @ 70 V. This difference does not affect substitution eligibility for general-purpose rectification applications. Circuit designs must evaluate leakage current requirements for specific low-power or precision applications.

Q: Are there differences in reverse recovery time?

A: The BAV70LT1G specifies reverse recovery time (trr) of 6 ns. The BAV70 does not provide this parameter in the available documentation. Both parts are classified as small signal diodes with any speed rating, suitable for general-purpose applications.

Q: What is the operating temperature range for each part?

A: The BAV70 specifies maximum junction temperature of 150°C. The BAV70LT1G specifies operating temperature range of −55°C to 150°C. Both parts support the same maximum junction temperature; the BAV70LT1G provides extended low-temperature operation capability.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
