Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B270BE-13 is determined by strict parametric equivalence across the following criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 790 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AA, SMB
• Operating Temperature - Junction: -65°C ~ 150°C
• Technology: Schottky

Allowable Variation Parameters:

• Current - Reverse Leakage @ Vr: 7 µA to 7 mA @ 70 V (within acceptable leakage tolerance)
• Capacitance @ Vr, F: 70pF to 75pF @ 4V, 1MHz (minor capacitive variation)
• Product Status: Active substitutes preferred over Obsolete
• Packaging Format: Tape & Reel (TR) acceptable for bulk applications

Two substitute parts meet these criteria and are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

B270-13-F Selection Criteria:

The B270-13-F is an Active product status equivalent offering direct parametric substitution for the obsolete B270BE-13. This part maintains identical voltage, current, and forward voltage specifications. The reverse leakage current specification of 7 mA at 70 V represents an allowable variation within acceptable diode leakage tolerance ranges. Capacitance variation of 75pF versus 70pF is negligible for most rectification applications. This substitute is suitable for standard industrial and commercial applications where automotive qualification is not required. RoHS3 compliance and REACH unaffected status support regulatory compliance requirements.

B270Q-13-F Selection Criteria:

The B270Q-13-F is an Active product status equivalent with Automotive grade designation and AEC-Q101 qualification. This part provides identical parametric performance to the B270BE-13 with reverse leakage current of 7 µA at 70 V, matching the original specification precisely. Capacitance specification of 75pF represents minimal variation. Selection of B270Q-13-F is appropriate for automotive applications, safety-critical systems, or designs requiring AEC-Q101 qualified components. RoHS3 compliance and REACH unaffected status support regulatory requirements in automotive and regulated markets.

Both substitutes are manufactured by Diodes Incorporated and maintain full compatibility with existing PCB layouts and thermal management designs utilizing the DO-214AA SMB package footprint.

Frequently Asked Questions (FAQ)

Q: Can B270-13-F and B270Q-13-F be used interchangeably with B270BE-13?

A: Both parts are parametric equivalents meeting the core electrical specifications of the B270BE-13. B270-13-F is suitable for standard applications. B270Q-13-F includes automotive qualification and is required for automotive or safety-critical applications. Selection depends on application requirements and regulatory compliance needs.

Q: What is the significance of the reverse leakage current difference between B270BE-13 (7 µA) and B270-13-F (7 mA)?

A: The B270-13-F exhibits higher reverse leakage current at 7 mA compared to the B270BE-13 at 7 µA. This difference is within acceptable tolerance for Schottky diode rectifiers in standard rectification circuits. Applications with stringent leakage requirements should select B270Q-13-F, which matches the original 7 µA specification.

Q: Are there package compatibility considerations when substituting these parts?

A: All three parts utilize the DO-214AA SMB surface mount package. PCB footprints, solder pad layouts, and thermal characteristics are identical. No design modifications are required for package compatibility.

Q: What is the difference between standard and automotive grade versions?

A: B270Q-13-F carries Automotive grade designation with AEC-Q101 qualification, indicating compliance with automotive industry reliability and qualification standards. B270-13-F is standard grade without automotive qualification. Automotive applications must use B270Q-13-F.

Q: Why is the B270BE-13 listed as Obsolete?

A: Obsolete status indicates the part has been discontinued from active production by Diodes Incorporated. The substitute parts B270-13-F and B270Q-13-F are Active products providing equivalent functionality and are recommended for new designs and ongoing production requirements.

Q: Are there differences in moisture sensitivity or packaging format?

A: B270BE-13 packaging format is not specified. B270-13-F and B270Q-13-F are supplied in Tape & Reel (TR) format with Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. This format is standard for high-volume production and automated assembly.

Q: Do all three parts meet RoHS and REACH compliance requirements?

A: B270BE-13, B270-13-F, and B270Q-13-F are all RoHS3 compliant. B270BE-13 is REACH Affected; B270-13-F and B270Q-13-F are REACH Unaffected. For applications requiring REACH unaffected status, B270-13-F or B270Q-13-F are appropriate selections.
