Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT86S-TR are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Identical Electrical Specifications, Packaging Variation): The BAT86S-TAP shares all electrical parameters with the BAT86S-TR, including 50 V reverse voltage, 200 mA rectified current, 900 mV forward voltage at 100 mA, and 8 pF capacitance. The primary difference is packaging format: BAT86S-TAP is supplied in Cut Tape (CT) format versus Tape & Reel (TR) for the main part. Both utilize the DO-35 through-hole package configuration.

Manufacturer Recommended Substitutes (Electrical Variations, Compatible Function): The BAT42, BAT86,113, and BAT86,133 are classified as manufacturer-recommended alternatives based on matching 200 mA current rating and through-hole mounting compatibility. These parts differ in reverse voltage rating, forward voltage characteristics, or package format while maintaining functional equivalence within specified application parameters.

Key substitution criteria:

• Reverse voltage rating (50 V or lower)
• Average rectified current (200 mA minimum)
• Forward voltage drop characteristics
• Through-hole mounting configuration
• DO-35 or DO-34 package compatibility
• Automotive grade and AEC-Q101 qualification status

Parameter Comparison

Engineering Selection Recommendations

BAT86S-TAP is the direct parametric equivalent for BAT86S-TR applications. All electrical specifications are identical, including 50 V reverse voltage, 200 mA current rating, 900 mV forward voltage, and 8 pF capacitance. The sole distinction is packaging format (Cut Tape versus Tape & Reel). Selection of BAT86S-TAP is appropriate when tape format inventory is available and reel packaging is not required. Both parts maintain Active product status, AEC-Q101 automotive qualification, and ROHS3 compliance.

BAT42 is a manufacturer-recommended substitute with reduced reverse voltage rating (30 V versus 50 V). This part is suitable for applications where the circuit design operates at 30 V or lower reverse bias conditions. BAT42 exhibits lower reverse leakage current (500 nA at 25 V) and slightly higher forward voltage (1 V at 200 mA) compared to BAT86S-TR. Selection requires confirmation that the 30 V rating satisfies circuit requirements.

BAT86,113 and BAT86,133 are manufacturer-recommended alternatives that maintain the 50 V reverse voltage and 900 mV forward voltage specifications of BAT86S-TR. These parts differ in package format (DO-34 versus DO-35) and supplier designation. BAT86,113 is supplied in Cut Tape format by Nexperia USA Inc., while BAT86,133 is supplied in Bulk format by NXP USA Inc. Both parts are suitable for direct functional replacement when DO-34 package compatibility is acceptable.

All substitute parts maintain Active product status, ROHS3 compliance, and through-hole mounting configuration. Selection among substitutes is determined by packaging availability, reverse voltage requirements, and forward voltage characteristics specific to circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can BAT86S-TAP be used as a direct replacement for BAT86S-TR?

A: Yes. BAT86S-TAP is a parametric equivalent with identical electrical specifications (50 V reverse voltage, 200 mA current, 900 mV forward voltage, 8 pF capacitance). The difference is packaging format: BAT86S-TAP is supplied in Cut Tape format while BAT86S-TR is supplied in Tape & Reel format. Both use the DO-35 through-hole package.

Q: What is the primary difference between BAT86S-TR and BAT42?

A: The BAT42 has a reduced reverse voltage rating of 30 V compared to 50 V for BAT86S-TR. Both share the same 200 mA current rating and DO-35 package. BAT42 is suitable only for applications operating at 30 V reverse bias or lower. BAT42 exhibits lower reverse leakage current (500 nA at 25 V) and higher forward voltage (1 V at 200 mA).

Q: Are BAT86,113 and BAT86,133 compatible with BAT86S-TR?

A: Both BAT86,113 and BAT86,133 maintain the 50 V reverse voltage and 900 mV forward voltage specifications of BAT86S-TR. The primary difference is package format: BAT86,113 and BAT86,133 use DO-34 package while BAT86S-TR uses DO-35 package. Physical dimensions differ between DO-34 and DO-35, requiring verification of PCB layout compatibility before substitution.

Q: What packaging formats are available for BAT86 Schottky diodes?

A: BAT86S-TR is supplied in Tape & Reel (TR) format. BAT86S-TAP is supplied in Cut Tape (CT) format. BAT86,113 is supplied in Cut Tape (CT) format. BAT86,133 is supplied in Bulk format. All utilize through-hole mounting with either DO-35 (DO-204AH) or DO-34 (DO-204AG) package configurations.

Q: Do all substitute parts meet automotive qualification requirements?

A: BAT86S-TR, BAT86S-TAP, BAT86,113, and BAT86,133 all carry AEC-Q101 automotive qualification and Automotive grade designation. BAT42 does not specify automotive grade or AEC-Q101 qualification in the provided data. Verification of automotive compliance is required if BAT42 is selected for automotive applications.

Q: What is the difference between DO-35 and DO-34 packages?

A: DO-35 (DO-204AH) and DO-34 (DO-204AG) are both axial through-hole diode packages with different physical dimensions. DO-35 is slightly larger than DO-34. PCB layout and component spacing must be verified before substituting between these package types, as lead spacing and body length differ.

Q: Can BAT86S-TR be substituted in high-voltage applications exceeding 50 V?

A: No. BAT86S-TR is rated for maximum 50 V reverse voltage. Applications requiring higher reverse voltage ratings require selection of alternative diode types with higher voltage specifications. Exceeding the 50 V rating will result in component failure.

Q: What is the significance of the 8 pF capacitance specification?

A: The 8 pF capacitance at 1 V and 1 MHz represents the junction capacitance of the diode. This parameter is critical for high-frequency switching applications and signal coupling circuits. BAT42 has slightly lower capacitance (7 pF), which may provide marginal performance benefits in high-frequency applications. BAT86S-TR, BAT86S-TAP, BAT86,113, and BAT86,133 all specify 8 pF capacitance.
