Substitute Part Grouping Explanation

Substitute parts for the BAV20,113 are classified based on the following electrical and mechanical criteria:

Parametric Equivalent Classification: Parts maintaining identical or superior ratings across all critical parameters: reverse voltage (Vr), average rectified current (Io), forward voltage (Vf), reverse recovery time (trr), and reverse leakage current. These parts are direct functional replacements with no circuit performance degradation.

Similar Classification: Parts with variations in one or more electrical parameters that may require circuit evaluation. Variations include reduced reverse voltage rating, reduced current capacity, or different speed classification. These parts function in applications where the reduced parameter does not exceed circuit requirements.

Critical Parameters for Substitution:

Voltage - DC Reverse (Vr) must equal or exceed circuit maximum reverse voltage
Current - Average Rectified (Io) must equal or exceed circuit maximum forward current
Reverse Recovery Time (trr) must support required switching frequency
Mounting Type must be Through Hole
Package / Case must be compatible with PCB layout (DO-204AH, DO-35, or Axial)

Engineering Selection Recommendations

BAV20,133 (Parametric Equivalent): This part is a direct functional equivalent to BAV20,113, differing only in packaging format (Bulk versus Cut Tape). Both parts maintain identical electrical specifications including 150 V reverse voltage, 250 mA current rating, 1.25 V forward voltage, and 50 ns reverse recovery time. Both are ROHS3 compliant and rated to 175°C junction temperature. Selection between BAV20,113 and BAV20,133 is determined by supply chain availability and packaging requirements rather than electrical performance.

1N4938-1 (Similar - Reduced Current Rating): This Microchip Technology part provides 175 V reverse voltage (exceeding BAV20,113 by 25 V) but is limited to 100 mA average rectified current, representing a 60% reduction from the 250 mA BAV20,113 rating. The 1N4938-1 is classified as Small Signal speed category rather than Fast Recovery. This part is suitable only for applications where circuit current requirements do not exceed 100 mA. RoHS non-compliance status requires evaluation against procurement requirements.

FDH300ATR and FDH300TR (Similar - Reduced Voltage and Current): Both onsemi parts are rated for 125 V reverse voltage (17% reduction) and 200 mA average rectified current (20% reduction) compared to BAV20,113. Forward voltage is reduced to 1 V at 200 mA. Both are classified as Small Signal speed category. These parts are suitable for applications where circuit maximum reverse voltage does not exceed 125 V and maximum current does not exceed 200 mA. Both are ROHS3 compliant. FDH300ATR and FDH300TR are electrically identical; selection is based on packaging format (Cut Tape).

FDH333TR (Similar - Reduced Voltage and Current): This onsemi part is rated for 125 V reverse voltage and 200 mA average rectified current with forward voltage of 1.15 V at 300 mA. Reverse leakage current is specified at 3 nA at 125 V, representing higher leakage than BAV20,113. This part is suitable for applications where circuit maximum reverse voltage does not exceed 125 V and maximum current does not exceed 200 mA. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can BAV20,133 be used as a direct replacement for BAV20,113?

A: Yes. BAV20,133 is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Bulk versus Cut Tape). Both parts are rated for 150 V, 250 mA, with 1.25 V forward voltage and 50 ns reverse recovery time. Both are ROHS3 compliant and rated to 175°C.

Q: What is the primary limitation of the 1N4938-1 as a substitute?

A: The 1N4938-1 is limited to 100 mA average rectified current, which is 60% lower than the BAV20,113 rating of 250 mA. This part is suitable only for circuits where maximum forward current does not exceed 100 mA. Additionally, the 1N4938-1 is RoHS non-compliant, which may conflict with procurement specifications.

Q: Can FDH300TR be used in place of BAV20,113 in all applications?

A: No. FDH300TR is rated for 125 V reverse voltage and 200 mA average rectified current, both lower than BAV20,113 specifications. This part is suitable only for applications where circuit maximum reverse voltage does not exceed 125 V and maximum forward current does not exceed 200 mA. Circuit evaluation is required to confirm compatibility.

Q: What is the difference between FDH300ATR and FDH300TR?

A: FDH300ATR and FDH300TR are electrically identical. Both are rated for 125 V reverse voltage, 200 mA average rectified current, and 1 V forward voltage at 200 mA. The difference is packaging format: FDH300ATR is supplied in Cut Tape (CT) format, as is FDH300TR. Selection is based on supply chain availability.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts (BAV20,133, 1N4938-1, FDH300ATR, FDH300TR, FDH333TR) are through-hole mounted components with DO-204AH, DO-35, or Axial package configurations, maintaining compatibility with PCB layouts designed for BAV20,113.

Q: Which substitute parts are ROHS3 compliant?

A: BAV20,133, FDH300ATR, FDH300TR, and FDH333TR are all ROHS3 compliant. The 1N4938-1 is RoHS non-compliant and requires evaluation against procurement requirements before selection.

Q: What is the difference in reverse recovery time between BAV20,113 and the onsemi FDH series?

A: BAV20,113 specifies 50 ns reverse recovery time and is classified as Fast Recovery (≤ 500ns, > 200mA). The FDH300ATR, FDH300TR, and FDH333TR parts are classified as Small Signal (≤ 200mA, Any Speed) with reverse recovery time not specified in the provided data. This classification difference indicates different switching performance characteristics.
