B160AF-13 Equivalent & Substitute Parts

Part Overview

The B160AF-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 60 V DC reverse voltage and 1 A average rectified current in a surface mount SMAF package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance is required across different manufacturing sources, higher current ratings are acceptable for the application, or when alternative package variants of the same electrical class are needed to meet supply chain or design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B160AF-13 are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60 V
• Technology: Must be Schottky type
• Speed: Must meet Fast Recovery specification (≤ 500ns, > 200mA)
• Package / Case: Must be DO-221AC with SMA Flat Leads
• Mounting Type: Must be Surface Mount
• RoHS Status: Must be ROHS3 Compliant

Secondary Compatibility Factors:

• Current - Average Rectified (Io): Substitute parts rated at 5 A are acceptable as they exceed the 1 A requirement and maintain backward compatibility
• Voltage - Forward (Vf): Variations within the Schottky diode class are acceptable provided reverse voltage and current ratings are met
• Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges are acceptable

Both identified substitute parts meet all primary criteria and exceed current rating requirements, making them suitable for applications where the B160AF-13 is specified.

Parameter Comparison

Engineering Selection Recommendations

B160AF-13 (Diodes Incorporated): Primary choice for applications requiring the specified 1 A current rating with the lowest forward voltage drop at rated current (650 mV @ 1 A). Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range of -55°C to 150°C supports standard industrial applications.

SK56AFL-TP (Micro Commercial Co): Suitable for applications where 5 A current capacity is required or where supply chain diversification from Diodes Incorporated is necessary. Maintains 60 V reverse voltage rating and fast recovery characteristics. Operating temperature range limited to -55°C to 125°C compared to the primary part. Active product status with RoHS3 compliance.

VSSAF5M6HM3/H (Vishay): Qualified for automotive applications requiring AEC-Q101 certification and extended operating temperature range (-40°C to 175°C). Provides 5 A current rating with forward voltage of 660 mV @ 5 A. TMBS® and SlimSMA™ series designation indicates optimized thermal and package characteristics. Active product status with RoHS3 compliance. Suitable for high-temperature environments where the primary part's maximum junction temperature of 150°C is insufficient.

All three parts are Active products with ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, confirming regulatory equivalence for component selection purposes.

Frequently Asked Questions (FAQ)

Q: Can SK56AFL-TP or VSSAF5M6HM3/H be used as direct replacements for B160AF-13?

A: Yes, both substitute parts are electrically and mechanically compatible. They share the same 60 V reverse voltage rating, DO-221AC package with SMA flat leads, fast recovery Schottky technology, and surface mount configuration. The higher 5 A current rating of the substitutes exceeds the 1 A requirement and does not create incompatibility in circuits designed for the B160AF-13.

Q: What are the differences in forward voltage drop between these parts?

A: Forward voltage specifications are measured at different current levels. B160AF-13 is rated at 650 mV @ 1 A, SK56AFL-TP at 700 mV @ 5 A, and VSSAF5M6HM3/H at 660 mV @ 5 A. When operating at 1 A, the actual forward voltage of the 5 A rated parts will be lower than their specified maximum values. Circuit designs sensitive to forward voltage drop should account for these differences through thermal or electrical testing.

Q: Are there temperature range limitations when substituting these parts?

A: Yes. The B160AF-13 operates from -55°C to 150°C junction temperature. SK56AFL-TP is limited to -55°C to 125°C, which is more restrictive at the upper end. VSSAF5M6HM3/H extends to -40°C to 175°C, providing a wider operating window. Applications requiring operation above 150°C junction temperature must use VSSAF5M6HM3/H or verify that SK56AFL-TP's 125°C maximum is acceptable.

Q: What is the significance of the different capacitance values listed?

A: Capacitance values (45 pF, 210 pF, and 580 pF @ 4V, 1MHz) reflect junction capacitance characteristics. Higher capacitance in the substitute parts may affect high-frequency circuit performance, particularly in switching applications or RF circuits. Applications operating at frequencies above 1 MHz should evaluate whether the increased capacitance impacts circuit behavior.

Q: Why does VSSAF5M6HM3/H have automotive qualification?

A: VSSAF5M6HM3/H carries AEC-Q101 qualification and is designated as automotive grade. This indicates the part has undergone additional reliability testing and screening required for automotive applications. This qualification is not present in B160AF-13 or SK56AFL-TP. Use VSSAF5M6HM3/H when automotive-grade components are specified or required by design standards.

Q: Are all three parts available in the same packaging format?

A: All three parts use DO-221AC package with SMA flat leads and are supplied in Tape & Reel (TR) format. The VSSAF5M6HM3/H is designated as SlimSMA™ variant, which is a Vishay trademark for their DO-221AC implementation. The physical footprint and PCB land pattern are compatible across all three parts for surface mount assembly.

Q: What is the moisture sensitivity level for these parts?

A: All three parts are rated MSL 1 (Unlimited), indicating they have unlimited shelf life and do not require special moisture control during storage or handling. This simplifies inventory management and reduces the risk of moisture-related failures during assembly.
