B240BE-13 Equivalent & Substitute Parts

Part Overview

The B240BE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 40 V DC reverse voltage and 2 A average rectified current in a surface mount SMB (DO-214AA) package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement.

The B240BE-13 serves applications requiring fast recovery Schottky diode performance with low forward voltage drop characteristics. Equivalent parts are identified based on matching electrical specifications and mechanical compatibility within the SMB package category.

Engineering Selection Recommendations

Direct Manufacturer Replacement:

B240-13-F (Diodes Incorporated) is the active production equivalent from the original manufacturer. This part maintains the same base product number (B240) and is supplied in Cut Tape and Digi-Reel packaging formats. The B240-13-F extends the lower operating temperature limit to -65°C and carries ROHS3 compliance with MSL 1 rating. This part is recommended for direct substitution where procurement from the original manufacturer is preferred.

Parametric Equivalents - onsemi:

NRVBSS24NT3G, NRVBSS24T3G-VF01, and SS24T3G are parametric equivalents from onsemi. All three parts meet the core electrical and mechanical specifications. NRVBSS24NT3G and NRVBSS24T3G-VF01 carry AEC-Q101 automotive qualification. SS24T3G is supplied in Cut Tape and Digi-Reel packaging with the highest inventory availability (70,200 units).

Parametric Equivalents - Panjit International Inc.:

SK24-AU_R1_000A1 and SK24_R1_00001 are parametric equivalents from Panjit International Inc. Both parts feature lower reverse leakage current (90 µA @ 40V) compared to the original specification (200 µA @ 40V). SK24_R1_00001 offers the highest inventory availability among all substitutes (28,400 units) and is supplied in Tape & Reel packaging.

Product Status Consideration:

All substitute parts listed are in active production status, ensuring long-term availability and supply chain continuity. The original B240BE-13 is obsolete and should not be specified for new designs.

Compliance:

All substitute parts are ROHS3 compliant and carry REACH Unaffected or REACH Affected status as specified. Automotive-grade options (NRVBSS24NT3G, NRVBSS24T3G-VF01, SK24-AU_R1_000A1) with AEC-Q101 qualification are available for applications requiring automotive-level reliability.

Frequently Asked Questions (FAQ)
