B170B-13 Schottky Diode 70V 1A SMB Equivalent & Substitute Parts

Part Overview

The B170B-13 is a Schottky rectifier diode rated for 70V DC reverse voltage and 1A average rectified current in a Surface Mount SMB (DO-214AA) package. This diode is designed for fast recovery applications with switching speeds ≤500ns at currents >200mA. The B170B-13 is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B170B-13 is determined by electrical and mechanical parameter equivalence across the Schottky diode category. All substitute parts must maintain identical specifications for:

• Reverse voltage rating (70V)
• Average rectified current (1A)
• Forward voltage drop (790 mV @ 1A)
• Recovery speed (Fast Recovery ≤500ns, >200mA)
• Reverse leakage current (500 µA @ 70V)
• Junction capacitance (80pF @ 4V, 1MHz)
• Package type (DO-214AA, SMB)
• Operating temperature range (-65°C ~ 150°C)
• Moisture sensitivity level (MSL 1)

The substitute parts are grouped into two categories: direct packaging equivalents and parametric equivalents with automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

B170B-13-F is the direct functional equivalent to the B170B-13. Both parts share identical electrical specifications and package configuration. The B170B-13-F is currently in active production status with ROHS3 compliance and is supplied in Tape & Reel packaging format. This part is suitable for direct substitution in applications where the original B170B-13 was specified.

B170BQ-13-F is a parametric equivalent with automotive-grade qualification (AEC-Q101). This part maintains all electrical and mechanical specifications identical to the B170B-13 and B170B-13-F. The B170BQ-13-F is designated for automotive applications and carries AEC-Q101 qualification. Selection of this part is appropriate for designs requiring automotive-grade components or when AEC-Q101 certification is a design requirement.

Both substitute parts are ROHS3 compliant and address the RoHS non-compliance status of the discontinued B170B-13. Both substitute parts are supplied in Tape & Reel packaging, which is standard for production volume procurement.

Frequently Asked Questions (FAQ)

Q: Can B170B-13-F be used as a direct replacement for B170B-13?

A: Yes. The B170B-13-F is electrically and mechanically equivalent to the B170B-13. All electrical parameters, package type, and operating specifications are identical. The primary differences are product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between B170B-13-F and B170BQ-13-F?

A: Both parts are parametrically equivalent with identical electrical specifications and package configuration. The B170BQ-13-F carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. The B170B-13-F is standard-grade. Selection depends on application requirements and whether automotive qualification is necessary.

Q: Are there packaging differences between the substitute parts?

A: The B170B-13 is supplied in bulk packaging. Both B170B-13-F and B170BQ-13-F are supplied in Tape & Reel (TR) format, which is standard for surface mount component procurement and automated assembly processes.

Q: Do the substitute parts meet RoHS requirements?

A: Yes. Both B170B-13-F and B170BQ-13-F are ROHS3 compliant. The original B170B-13 is RoHS non-compliant. Substitution with either equivalent part addresses RoHS compliance requirements.

Q: Are the electrical characteristics identical across all three parts?

A: Yes. The B170B-13, B170B-13-F, and B170BQ-13-F share identical electrical specifications including reverse voltage (70V), average rectified current (1A), forward voltage drop (790 mV @ 1A), recovery speed (Fast Recovery ≤500ns, >200mA), reverse leakage current (500 µA @ 70V), and junction capacitance (80pF @ 4V, 1MHz).

Q: Which substitute part should be selected for new designs?

A: For standard applications, B170B-13-F is the appropriate selection as the direct active equivalent. For automotive applications or designs requiring AEC-Q101 qualification, B170BQ-13-F is the specified selection.
