Substitute Part Grouping Explanation

Substitution of the B150BE-13 is determined by equivalence in the following critical parameters:

Voltage Rating: Reverse voltage (Vr) must equal or exceed 50 V
Current Rating: Average rectified current (Io) must equal or exceed 1 A
Package Type: Surface Mount SMB (DO-214AA) package required for mechanical and thermal compatibility
Technology: Schottky diode technology for fast recovery characteristics
Speed Classification: Fast recovery performance ≤ 500ns at currents > 200mA

The B150B-13-F qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share the same base product number (B150), voltage rating (50 V), current rating (1 A), package type (SMB), and technology classification (Schottky).

Engineering Selection Recommendations

The B150B-13-F is the direct substitute for the obsolete B150BE-13. Both components are manufactured by Diodes Incorporated and maintain identical voltage and current ratings, package type, and technology classification.

Product Status Consideration: The B150BE-13 is obsolete, while the B150B-13-F is in active production. Selection of the B150B-13-F ensures continued component availability and supply chain stability.

Compliance Status: Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, ensuring regulatory equivalence for procurement and export purposes.

Parameter Variations: The B150B-13-F exhibits higher forward voltage (700 mV versus 650 mV), higher reverse leakage current (500 µA versus 100 µA), and higher junction capacitance (110 pF versus 45 pF). These variations remain within acceptable tolerances for Schottky diode applications and do not preclude direct substitution in standard rectification circuits.

Temperature Range: The B150B-13-F supports an extended minimum operating temperature (-65°C versus -55°C), providing additional thermal margin for low-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the B150B-13-F directly replace the B150BE-13 in existing designs?

A: Yes. Both parts share identical voltage ratings (50 V), current ratings (1 A), package type (SMB), and technology classification (Schottky). The B150B-13-F is the active production equivalent of the obsolete B150BE-13.

Q: What are the differences between these two parts?

A: The primary differences are product status (B150BE-13 is obsolete; B150B-13-F is active), forward voltage specification (650 mV versus 700 mV at 1 A), reverse leakage current (100 µA versus 500 µA at 50 V), junction capacitance (45 pF versus 110 pF at 4 V, 1 MHz), and minimum operating temperature (-55°C versus -65°C).

Q: Are there packaging differences between these parts?

A: Both parts use identical Surface Mount SMB (DO-214AA) packaging. The B150B-13-F is supplied in Tape & Reel (TR) format, which is standard for active production components. The B150BE-13 packaging format is not specified in available data.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The B150B-13-F is REACH unaffected, while the B150BE-13 is REACH affected.

Q: Which part should be selected for new designs?

A: The B150B-13-F should be selected for new designs. It is in active production, ensuring long-term availability and supply chain continuity. The B150BE-13 is obsolete and should not be specified for new applications.

Q: Are there any thermal considerations when substituting these parts?

A: The B150B-13-F supports an extended minimum operating temperature range (-65°C to 150°C) compared to the B150BE-13 (-55°C to 150°C). This provides additional thermal margin for low-temperature environments.
