BAV170 Equivalent & Substitute Parts

Part Overview

The BAV170 is a general-purpose diode array in a 1 Pair Common Cathode configuration, rated for 85 V DC reverse voltage and 125 mA average rectified current per diode. The device is packaged in a Surface Mount TO-236-3 (SOT-23-3) package and operates across a junction temperature range of -65°C to 150°C.

Substitute Part Grouping Explanation

Substitution of the BAV170 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Diode Configuration: 1 Pair Common Cathode (electrical pinout compatibility)
Package / Case: TO-236-3, SC-59, SOT-23-3 (mechanical and thermal compatibility)
Mounting Type: Surface Mount (assembly compatibility)
Technology: Standard (functional equivalence)

Electrical Performance Criteria:

Voltage - DC Reverse (Vr) (Max): Substitute must equal or exceed 85 V
Current - Average Rectified (Io) (per Diode): Substitute must equal or exceed 125 mA
Voltage - Forward (Vf) (Max) @ If: Operating point compatibility
Reverse Recovery Time (trr): Speed classification compatibility
Current - Reverse Leakage @ Vr: Leakage performance

Environmental Criteria:

Operating Temperature - Junction: Substitute must support -65°C to 150°C range or equivalent maximum rating

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical specifications) and Direct Manufacturers (alternative sources with comparable or enhanced electrical performance).

Engineering Selection Recommendations

Primary Recommendation: BAV170-7-F (Diodes Incorporated)

The BAV170-7-F is a parametric equivalent to the original BAV170, offering identical electrical specifications across all critical parameters: 85 V reverse voltage, 125 mA average rectified current, 1.1 V forward voltage at 50 mA, and 3 µs reverse recovery time. The part is currently Active in product status and available in Tape & Reel packaging. This part provides direct functional replacement with no design modifications required.

Secondary Recommendation: BAV170,215 (Nexperia USA Inc.)

The BAV170,215 is an Active product offering enhanced current capability (215 mA versus 125 mA) within the same SOT-23-3 package. The reverse voltage is reduced to 75 V, which remains above the original 85 V specification. This part is suitable for applications where higher current capacity is beneficial and the 75 V rating is acceptable. The part is currently in Active status with substantial inventory availability.

Alternative Recommendation: BAV170-AU_R1_000A1 (Panjit International Inc.)

The BAV170-AU_R1_000A1 is an Active product qualified to AEC-Q101 automotive standards, rated for 75 V reverse voltage and 200 mA average rectified current. This part is suitable for automotive-grade applications requiring enhanced current handling. The lower reverse voltage rating (75 V) is acceptable for most general-purpose applications.

Not Recommended: BAV170E6327HTSA1, BAV170E6433HTMA1, BAV70E6433HTMA1 (Infineon Technologies)

These parts carry Last Time Buy status, indicating discontinued or end-of-life product lines. While electrically compatible, their limited availability and discontinuation trajectory make them unsuitable for new designs or long-term supply chain planning.

Not Recommended: PMBD6100,215 (Nexperia USA Inc.)

The PMBD6100,215 has a reduced reverse voltage rating of 70 V, which falls below the original BAV170 specification of 85 V. This part is not suitable as a direct substitute for applications requiring the full 85 V rating.

Frequently Asked Questions (FAQ)

Q: Can BAV170-7-F be used as a direct replacement for BAV170?

A: Yes. The BAV170-7-F is a parametric equivalent with identical electrical specifications: 85 V reverse voltage, 125 mA average rectified current, 1.1 V forward voltage at 50 mA, and 3 µs reverse recovery time. No circuit modifications are required. The part is currently Active and available in production quantities.

Q: What is the difference between BAV170 and BAV170,215?

A: The BAV170,215 offers higher current capacity (215 mA versus 125 mA) but has a reduced reverse voltage rating (75 V versus 85 V). Both parts use the same SOT-23-3 package and 1 Pair Common Cathode configuration. The BAV170,215 is suitable for applications where the 75 V rating is acceptable and higher current handling is required.

Q: Are Infineon BAV170E6327HTSA1 and BAV170E6433HTMA1 suitable for new designs?

A: These parts carry Last Time Buy status, indicating end-of-life product lines. They are not recommended for new designs due to limited future availability and discontinuation risk. The BAV170-7-F is the preferred alternative for new applications.

Q: Does the BAV170-AU_R1_000A1 require any special handling or qualification?

A: The BAV170-AU_R1_000A1 is qualified to AEC-Q101 automotive standards and carries Automotive grade designation. It is suitable for automotive applications and general-purpose use. Standard surface mount assembly and handling procedures apply.

Q: Can PMBD6100,215 replace BAV170 in all applications?

A: No. The PMBD6100,215 has a maximum reverse voltage rating of 70 V, which is below the original BAV170 specification of 85 V. This part is not suitable for applications requiring the full 85 V rating. Verify application voltage requirements before substitution.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts listed are packaged in TO-236-3, SC-59, SOT-23-3 Surface Mount configuration, ensuring mechanical and thermal compatibility with the original BAV170. Tape & Reel and Cut Tape packaging options are available depending on the specific part number and supplier.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts support a maximum junction temperature of 150°C. The original BAV170 and BAV170-7-F support a minimum junction temperature of -65°C. The BAV170-AU_R1_000A1 supports -55°C to 150°C. Verify application temperature requirements against the specific part's operating range.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant. The original BAV170 is RoHS non-compliant. All parts are REACH Unaffected and carry EAR99 ECCN classification.
