BAV70S E6433 Equivalent & Substitute Parts

Part Overview

The BAV70S E6433 is a general-purpose diode array manufactured by Infineon Technologies, configured as a 2 Pair Common Cathode device in a 6-VSSOP (SOT-363) surface mount package. This component is rated for 80 V DC reverse voltage and 200 mA average rectified current per diode, with a maximum forward voltage of 1.25 V at 150 mA. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional compatibility while meeting application requirements. Substitute parts must preserve the diode configuration, mounting type, and electrical performance envelope to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAV70S E6433 is determined by strict adherence to the following critical parameters:

Configuration Match: All substitute parts must maintain the 2 Pair Common Cathode diode configuration to ensure pin-level compatibility and circuit functionality.

Package Compatibility: All substitutes must use the 6-VSSOP, SC-88, or SOT-363 surface mount package designation to permit direct PCB placement without layout modification.

Electrical Performance Envelope: Substitute parts must meet or exceed the minimum electrical specifications of the original part. This includes:

• Voltage - DC Reverse (Vr) rating of 80 V or higher
• Current - Average Rectified (Io) rating of 200 mA or higher per diode
• Forward voltage (Vf) of 1.25 V or lower at 150 mA
• Reverse recovery time (trr) of 4 ns or faster
• Operating temperature range supporting 150°C maximum junction temperature

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level to ensure regulatory and manufacturing process compatibility.

The identified substitute parts BAV70SH6327XTSA1, BAV70S,115, and BAV70S,135 satisfy these criteria through parametric equivalence or enhanced electrical performance within the same package family.

Parameter Comparison

Engineering Selection Recommendations

BAV70SH6327XTSA1 (Infineon Technologies): This part provides parametric equivalence to the BAV70S E6433 with identical electrical specifications and the same 6-VSSOP package. However, the product status is Last Time Buy, indicating limited future availability. This substitute is suitable for immediate replacement needs but should not be selected for long-term production planning due to supply discontinuation trajectory.

BAV70S,115 (Nexperia USA Inc.): This part offers enhanced electrical performance with 100 V reverse voltage rating and 250 mA average rectified current, exceeding the original part specifications. The part maintains active product status with substantial inventory availability (157,261 pcs). The package designation is 6-TSSOP, which is mechanically and electrically compatible with SOT-363 within the SC-88 family. This substitute is suitable for applications where the original BAV70S E6433 specifications are met or exceeded.

BAV70S,135 (Nexperia USA Inc.): This part is functionally identical to BAV70S,115 with the same enhanced electrical performance (100 V, 250 mA) and active product status. Inventory availability is 51,145 pcs. The 6-TSSOP package is compatible with SOT-363. Selection between BAV70S,115 and BAV70S,135 should be based on supply chain availability and procurement lead time requirements.

For applications requiring strict parametric equivalence with minimal electrical margin, BAV70SH6327XTSA1 is the direct replacement. For applications tolerating enhanced performance specifications, BAV70S,115 or BAV70S,135 are preferred due to active product status and superior long-term availability.

Frequently Asked Questions (FAQ)

Q: Can BAV70S,115 or BAV70S,135 be used as direct replacements for BAV70S E6433?

A: Yes. Both parts maintain the 2 Pair Common Cathode configuration and SOT-363 package family compatibility. The enhanced voltage (100 V vs. 80 V) and current (250 mA vs. 200 mA) ratings exceed the original specifications, making them functionally compatible for applications designed around the BAV70S E6433 electrical envelope.

Q: What is the difference between 6-VSSOP and 6-TSSOP packages?

A: Both designations refer to variants within the SOT-363 package family with identical pin counts and pitch. The mechanical and electrical compatibility permits direct PCB substitution without layout modification.

Q: Why does BAV70SH6327XTSA1 have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has announced discontinuation. This part should be used only for immediate replacement needs. For new designs or long-term production, BAV70S,115 or BAV70S,135 are recommended due to active product status.

Q: Are there differences in reverse leakage current between the substitute parts?

A: Yes. BAV70S E6433 and BAV70SH6327XTSA1 specify 150 nA @ 70 V, while BAV70S,115 and BAV70S,135 specify 500 nA @ 80 V. This difference is within acceptable limits for general-purpose rectification applications but should be evaluated for precision analog circuits requiring minimal leakage.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All identified substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original BAV70S E6433 compliance profile.
