Substitute Part Grouping Explanation

Substitution of the BAV70T216 is determined by strict electrical and mechanical compatibility criteria. The following parameters must be maintained or exceeded in any substitute component:

Mandatory Compatibility Parameters:

Diode Configuration: 1 Pair Common Cathode
Package / Case: TO-236-3, SC-59, SOT-23-3
Supplier Device Package: SSD3
Mounting Type: Surface Mount
Current - Average Rectified (Io): 215 mA (DC) minimum
Voltage - DC Reverse (Vr): 70 V minimum
Voltage - Forward (Vf): 1.25 V @ 150 mA maximum
Reverse Recovery Time (trr): 4 ns maximum
Operating Temperature - Junction: 150°C maximum
Technology: Standard
RoHS Status: ROHS3 Compliant

The BAV70HMT116 qualifies as a direct substitute based on these criteria. While the BAV70HMT116 features a higher maximum reverse voltage rating (80 V versus 70 V), this represents an uprated specification that maintains full backward compatibility with the original BAV70T216 design requirements. All other electrical and mechanical parameters remain identical or equivalent.

Engineering Selection Recommendations

The BAV70HMT116 is the qualified substitute for the obsolete BAV70T216. Selection of this substitute is based on the following engineering criteria:

Product Status: The BAV70T216 is classified as Obsolete, making the BAV70HMT116 (Active status) the appropriate replacement to ensure continued component availability and supply chain continuity.

Compliance & Certifications: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards. The BAV70HMT116 carries REACH Unaffected status and EAR99 ECCN classification.

Electrical Compatibility: The BAV70HMT116 maintains identical performance across all critical electrical parameters: forward voltage, reverse recovery time, rectified current capacity, and junction temperature rating. The increased reverse voltage rating (80 V versus 70 V) provides enhanced voltage margin without affecting circuit operation in applications designed for the original 70 V specification.

Mechanical & Package Compatibility: Both components utilize identical Surface Mount packaging (TO-236-3, SC-59, SOT-23-3) with SSD3 supplier device package designation, ensuring direct PCB footprint compatibility and assembly process compatibility.

Availability: The BAV70HMT116 is available in active production with substantial inventory (3328 Pcs), compared to the obsolete BAV70T216 status.

Frequently Asked Questions (FAQ)

Q: Can the BAV70HMT116 be used as a direct replacement for the BAV70T216 in existing circuit designs?

A: Yes. The BAV70HMT116 maintains identical electrical performance across all critical parameters (forward voltage, reverse recovery time, rectified current, and junction temperature). The higher reverse voltage rating (80 V versus 70 V) provides additional voltage margin and does not affect compatibility with circuits designed for 70 V operation.

Q: Are the physical packages identical between BAV70T216 and BAV70HMT116?

A: Yes. Both components use the TO-236-3 (SC-59, SOT-23-3) Surface Mount package with SSD3 supplier device package designation. PCB footprints and assembly processes are identical.

Q: What is the difference in reverse leakage current between these components?

A: The BAV70T216 specifies 2.5 µA reverse leakage at 70 V, while the BAV70HMT116 specifies 500 nA reverse leakage at 80 V. The BAV70HMT116 exhibits lower reverse leakage current, which represents improved performance characteristics.

Q: Are both components RoHS compliant?

A: Yes. Both the BAV70T216 and BAV70HMT116 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the BAV70T216 listed as Obsolete?

A: The BAV70T216 has been discontinued by the manufacturer. The BAV70HMT116 represents the active production equivalent that maintains full electrical and mechanical compatibility.

Q: What packaging options are available for the BAV70HMT116?

A: The BAV70HMT116 is supplied in Cut Tape (CT) and Digi-Reel® packaging, as well as Tape & Reel (TR) format for production quantities.
