• Current - Average Rectified (Io): 3 A minimum
• Voltage - Forward (Vf) (Max) @ If: 790 mV @ 3 A maximum
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS3 Compliant status
• ECCN: EAR99

The B3100-13-F is identified as a direct substitute for the B3100CE-13. Both components share the same base product number (B3100), manufacturer (Diodes Incorporated), and electrical rating specifications. The B3100-13-F maintains active product status and is available in higher inventory quantities with Cut Tape (CT) and Digi-Reel® packaging options.

Engineering Selection Recommendations

Primary Substitute: B3100-13-F

The B3100-13-F is the direct equivalent for the obsolete B3100CE-13. Selection of this substitute is based on the following engineering factors:

1. Product Status: The B3100CE-13 is obsolete. The B3100-13-F maintains active production status with significantly higher inventory availability (17,400 pcs vs. 702 pcs), ensuring long-term supply chain continuity.

2. Electrical Equivalence: Both components meet identical electrical specifications for voltage rating (100 V), current rating (3 A), forward voltage drop (790 mV @ 3 A), and switching speed (Fast Recovery ≤ 500ns). Minor variations in reverse leakage current (300 µA vs. 500 µA @ 100 V) and junction capacitance (105 pF vs. 100 pF @ 4V, 1MHz) remain within acceptable operating ranges for Schottky rectifier applications.

3. Mechanical Compatibility: Both components utilize identical DO-214AB SMC surface mount packaging, ensuring direct PCB footprint compatibility without layout modifications.

4. Compliance Alignment: Both components maintain ROHS3 compliance and EAR99 ECCN classification, supporting regulatory and export requirements.

5. Temperature Operating Range: The B3100-13-F operating range (-55°C ~ 125°C) encompasses the majority of standard industrial and commercial applications. Applications requiring operation above 125°C junction temperature require design review.

6. Packaging Options: The B3100-13-F is available in Cut Tape (CT) and Digi-Reel® packaging, providing flexibility for both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the B3100-13-F be used as a direct replacement for the B3100CE-13 without PCB modifications?

A: Yes. Both components share identical DO-214AB SMC package geometry and surface mount footprints. No PCB layout changes are required for substitution.

Q: What is the significance of the higher reverse leakage current in the B3100-13-F (500 µA vs. 300 µA)?

A: The reverse leakage current specification defines the maximum leakage current when the diode is reverse-biased at rated voltage. The B3100-13-F specification of 500 µA @ 100 V remains within acceptable limits for standard rectifier applications. Applications with specific leakage current requirements below 500 µA require design evaluation.

Q: Why does the B3100-13-F have a lower maximum junction temperature rating (-55°C ~ 125°C vs. -55°C ~ 150°C)?

A: The B3100-13-F maximum junction temperature of 125°C is typical for active production Schottky rectifiers in this current and voltage class. Applications requiring sustained operation above 125°C junction temperature require thermal management review or alternative component selection.

Q: Are there packaging differences between the B3100CE-13 and B3100-13-F?

A: Both components use DO-214AB SMC surface mount packaging. The B3100-13-F is available in Cut Tape (CT) and Digi-Reel® packaging formats, while the B3100CE-13 packaging format is not specified in available data. Both formats are compatible with standard surface mount assembly equipment.

Q: What is the difference between the B3100CE-13 and B3100-13-F part number designations?

A: The B3100CE-13 designation indicates an obsolete variant. The B3100-13-F designation indicates the active production equivalent from the same manufacturer. The "-13" suffix denotes the 100 V / 3 A rating specification. The "F" suffix in B3100-13-F indicates the active production variant with Cut Tape and Digi-Reel® packaging availability.

Q: Is the B3100-13-F ROHS3 compliant?

A: Yes. The B3100-13-F is ROHS3 compliant, matching the compliance status of the B3100CE-13. Both components meet Restriction of Hazardous Substances (RoHS) Directive requirements.

Q: Can the B3100-13-F be used in high-frequency switching applications?

A: Yes. The B3100-13-F maintains Fast Recovery switching characteristics (≤ 500ns, > 200mA Io), supporting high-frequency rectification and switching applications within the 3 A current rating.
