Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT46WJF are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:

• Reverse Voltage Rating (Vr): 100 V maximum
• Average Rectified Current (Io): 250 mA
• Forward Voltage (Vf): 850 mV maximum at 250 mA
• Reverse Recovery Time (trr): 5.9 ns
• Reverse Leakage Current: 9 µA at 100 V
• Package Type: SOD-323F (SC-90)
• Technology: Schottky
• Automotive Grade: AEC-Q101 qualified
• Compliance: ROHS3 compliant

The BAT46WJ,115 meets all electrical performance specifications and maintains identical package geometry, thermal characteristics, and automotive qualification. The primary distinction between the main part and substitute is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and a minor variance in capacitance specification (39 pF versus 21 pF at 0 V, 1 MHz), which does not affect functional equivalence for standard rectification and switching applications.

Parameter Comparison

Engineering Selection Recommendations

The BAT46WJ,115 is a direct functional equivalent to the BAT46WJF for all rectification and switching applications. Both parts are manufactured by Nexperia USA Inc., carry identical electrical specifications, and maintain AEC-Q101 automotive qualification with ROHS3 compliance. The parts are interchangeable at the circuit level, with no modifications to PCB layout or design required.

Selection between BAT46WJF and BAT46WJ,115 should be based on packaging and supply chain requirements:

• BAT46WJF (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel feeding.
• BAT46WJ,115 (Cut Tape & Digi-Reel®): Suitable for mixed-volume production, prototyping, and applications requiring flexible packaging formats.

The capacitance variance (21 pF versus 39 pF at 0 V, 1 MHz) does not affect functional performance in standard rectification circuits and does not impact switching speed or reverse recovery characteristics. Both parts operate within identical thermal and electrical performance envelopes.

Frequently Asked Questions (FAQ)

Q: Are BAT46WJF and BAT46WJ,115 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including reverse voltage rating (100 V), average rectified current (250 mA), forward voltage (850 mV @ 250 mA), reverse recovery time (5.9 ns), and reverse leakage current (9 µA @ 100 V). They are direct functional equivalents.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging provides components in cut tape format with optional Digi-Reel® carrier, offering flexibility for lower-volume or mixed-component assembly. Both formats contain identical components in the SOD-323F package.

Q: Does the capacitance difference (21 pF versus 39 pF) affect circuit performance?

A: The capacitance variance does not affect performance in standard rectification and switching applications. Both values fall within acceptable operating parameters for this component category and do not impact reverse recovery time, switching speed, or voltage regulation characteristics.

Q: Are both parts qualified for automotive applications?

A: Yes. Both BAT46WJF and BAT46WJ,115 carry AEC-Q101 automotive qualification and are rated for automotive-grade reliability. Both are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 1, Unlimited).

Q: Can I use BAT46WJ,115 as a direct replacement on existing PCBs designed for BAT46WJF?

A: Yes. Both parts use the identical SOD-323F package (SC-90) with matching pin configuration and footprint. No PCB modifications are required for substitution.

Q: What is the base product number for these parts?

A: The base product number is BAT46. Both BAT46WJF and BAT46WJ,115 are variants of this base product, differentiated by packaging format and minor specification variants.
