B1100BE-13 Equivalent & Substitute Parts

Part Overview

The B1100BE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 100 V DC reverse voltage and 1 A average rectified current in a Surface Mount SMB (DO-214AA) package. This part is classified as Obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

Schottky diodes in this voltage and current class are widely used in power supply circuits, reverse polarity protection, and high-frequency switching applications. The obsolete status of the B1100BE-13 requires engineers to evaluate active alternative parts that maintain electrical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the B1100BE-13 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage rating: 100 V DC reverse voltage (Vr) minimum
Package type: DO-214AA / SMB surface mount form factor
Technology: Schottky rectifier diode
RoHS3 compliance and REACH status alignment

Secondary Compatibility Factors:

Forward voltage (Vf) at rated current
Reverse leakage current (Ir) at rated voltage
Operating temperature range
Fast recovery speed characteristic (≤ 500ns, > 200mA)

Substitute parts are grouped into two categories:

Category 1: Direct Current Rating Equivalents (1 A rated) Parts maintaining the original 1 A average rectified current specification with identical voltage rating and package type.

Category 2: Higher Current Rating Substitutes (2 A to 3 A rated) Parts with elevated current ratings that provide design margin and enhanced thermal performance while maintaining 100 V voltage rating and SMB package compatibility. These parts are electrically backward-compatible for 1 A applications.

Frequently Asked Questions (FAQ)

Q: Can the B1100B-13-F be used as a direct replacement for the B1100BE-13?

A: Yes. The B1100B-13-F maintains identical electrical specifications: 100 V voltage rating, 1 A current rating, 790 mV forward voltage at 1 A, and fast recovery speed characteristic. Both parts use the DO-214AA (SMB) package. The B1100B-13-F is Active status with improved regulatory compliance (REACH Unaffected vs. REACH Affected).

Q: What is the difference between 1 A, 2 A, and 3 A rated parts in this voltage class?

A: Current rating indicates the maximum average rectified current the diode can conduct continuously. A 1 A part (B1100BE-13, B1100B-13-F) is rated for continuous operation at 1 A. A 2 A part (NBRS2H100T3G-VF01) or 3 A part (CMSH3-100M BK PBFREE, SK310B) can conduct higher currents with lower thermal stress. Higher-rated parts are electrically backward-compatible for lower-current applications and provide design margin.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and thermal compatibility with the original B1100BE-13 footprint and PCB layout.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current (Ir) is the small current that flows through the diode when reverse-biased. The B1100BE-13 specifies 200 µA at 100 V. Substitute parts range from 8 µA (NBRS2H100T3G-VF01) to 500 µA (B1100B-13-F, CMSH3-100M BK PBFREE). Lower leakage is advantageous in precision analog circuits and low-power applications. Higher leakage is acceptable in power supply and switching applications.

Q: Why do some substitute parts have higher forward voltage?

A: Forward voltage (Vf) varies with current density and junction temperature. The CMSH3-100M BK PBFREE and SK310B specify 850 mV at 3 A, compared to 790 mV at 1 A for the original part. This 60 mV difference reflects measurement at different current levels. At equivalent current density, forward voltage characteristics are comparable. Higher forward voltage results in slightly increased power dissipation in the diode.

Q: What does REACH Unaffected status mean?

A: REACH Unaffected indicates the part does not contain substances of very high concern (SVHC) listed under the EU REACH regulation. The original B1100BE-13 is REACH Affected, meaning it may contain listed substances. All substitute parts are REACH Unaffected, providing regulatory compliance for EU market applications.

Q: Is the NBRS2H100T3G-VF01 suitable for non-automotive applications?

A: Yes. The NBRS2H100T3G-VF01 is qualified to AEC-Q101 automotive standards, but this qualification does not restrict its use in non-automotive applications. The part is Active status with ROHS3 compliance and REACH Unaffected designation, making it suitable for general industrial and consumer applications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) supplies components on cut segments of carrier tape, suitable for lower-volume or mixed-component assembly. Both formats use the same component and are electrically identical. Selection depends on assembly process requirements and order volume.

Q: Can I use a 3 A rated part in a circuit designed for 1 A?

A: Yes. A 3 A rated part (CMSH3-100M BK PBFREE, SK310B) is electrically backward-compatible for 1 A applications. The higher current rating provides thermal margin and lower junction temperature at the same operating current. No circuit modification is required. The SMB package dimensions are identical across all current ratings.
