Key Parameters

Substitute Part Grouping Explanation

Substitution of the B250AE-13 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Technology: Schottky diode
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Requirements:

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Regulatory Compliance:

• RoHS3 Compliant
• ECCN: EAR99
• HTSUS: 8541.10.0080

The B250A-13-F meets all electrical and mechanical requirements for direct substitution. Both parts share the same base product number (B250), voltage rating, current rating, package type, and regulatory compliance status. The B250A-13-F is currently in active production status, making it the appropriate replacement for the obsolete B250AE-13.

Parameter Comparison

Engineering Selection Recommendations

The B250A-13-F is the direct substitute for the B250AE-13. Both components are manufactured by Diodes Incorporated and share identical electrical ratings for voltage and current specifications. The B250A-13-F is currently in active production status, whereas the B250AE-13 is obsolete.

Key considerations for component selection:

Voltage and Current Ratings: Both parts are rated for 50V DC reverse voltage and 2A average rectified current, ensuring functional equivalence in circuit applications.

Package Compatibility: Both components use the DO-214AC SMA surface mount package, permitting direct PCB layout compatibility without redesign.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN and HTSUS classifications, satisfying regulatory requirements for equivalent substitution.

Operating Temperature Range: The B250A-13-F extends the lower operating temperature limit to -65°C compared to the B250AE-13 at -55°C, providing broader thermal operating capability.

Production Status: Selection of the B250A-13-F ensures access to an actively manufactured component, eliminating supply chain risk associated with obsolete parts.

Frequently Asked Questions (FAQ)

Q: Can the B250A-13-F directly replace the B250AE-13 in existing designs?

A: Yes. Both components share identical voltage ratings (50V), current ratings (2A), package type (DO-214AC, SMA), and mounting configuration (surface mount). The B250A-13-F is electrically and mechanically compatible for direct substitution.

Q: What are the differences between the B250AE-13 and B250A-13-F?

A: The primary differences are: (1) Product status—B250AE-13 is obsolete while B250A-13-F is active; (2) Forward voltage—B250AE-13 is 650 mV @ 2A versus B250A-13-F at 700 mV @ 2A; (3) Reverse leakage current—B250AE-13 is 100 µA @ 50V versus B250A-13-F at 500 µA @ 50V; (4) Capacitance—B250AE-13 is 75 pF @ 4V, 1MHz versus B250A-13-F at 200 pF @ 4V, 1MHz; (5) Operating temperature range—B250AE-13 is -55°C to 150°C versus B250A-13-F is -65°C to 150°C.

Q: Are there packaging differences between these parts?

A: Both parts use identical packaging: DO-214AC, SMA surface mount package. Tape & Reel (TR) packaging is available for the B250A-13-F, which is the standard production format for active components.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the B250AE-13 and B250A-13-F are ROHS3 compliant, share the same ECCN classification (EAR99), and have identical HTSUS codes (8541.10.0080). Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the B250AE-13 classified as obsolete?

A: The B250AE-13 has been discontinued from active production by Diodes Incorporated. The B250A-13-F represents the current active equivalent in the B250 product family.

Q: What is the impact of higher reverse leakage current in the B250A-13-F?

A: The B250A-13-F exhibits 500 µA reverse leakage at 50V compared to 100 µA for the B250AE-13. This difference is within normal manufacturing variation for Schottky diodes and does not affect functional compatibility in standard rectifier applications.

Q: What is the significance of the higher capacitance in the B250A-13-F?

A: The B250A-13-F has 200 pF capacitance at 4V, 1MHz compared to 75 pF for the B250AE-13. This parameter affects high-frequency switching performance. Applications requiring specific capacitance characteristics should evaluate this difference against circuit requirements.
