GL41B/54 Equivalent & Substitute Parts

Part Overview

The GL41B/54 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 100 V DC reverse voltage and 1 A average rectified current in a surface mount DO-213AB (MELF glass) package. This diode operates within the SUPERECTIFIER® series and utilizes standard recovery technology. The part is currently active in production with 874 pieces in stock.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when compliance certifications differ between procurement requirements and available inventory.

Substitute Part Grouping Explanation

All substitute parts listed maintain electrical equivalence to the GL41B/54 across the critical parameters that define rectifier diode functionality: reverse voltage rating (100 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), recovery speed (standard >500ns), reverse leakage current (10 µA @ 100 V), and junction capacitance (8 pF @ 4V, 1MHz). All parts share identical package specifications (DO-213AB, MELF glass) and surface mount mounting type.

Substitution differences are determined by the following parameters:

Technology Type: Standard recovery versus Avalanche technology
Packaging Format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or unspecified packaging
RoHS Compliance Status: RoHS non-compliant versus ROHS3 compliant
Moisture Sensitivity Level (MSL): Specified as 1 (Unlimited) for compliant parts
Base Product Number: GL41, GL41B, 1N6479, or BYM10 series designation

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select GL41B-E3/96, GL41BHE3/96, 1N6479-E3/96, BYM10-100-E3/96, or BYM10-100-E3/97. All substitute parts carry ROHS3 compliant certification with MSL rating of 1 (Unlimited), whereas the primary GL41B/54 is RoHS non-compliant.

For Standard Technology Preference: GL41B-E3/96, GL41BHE3/96, and 1N6479-E3/96 maintain standard recovery technology identical to the GL41B/54. BYM10-100-E3/96 and BYM10-100-E3/97 employ avalanche technology while maintaining all electrical specifications.

For Tape & Reel Packaging: GL41BHE3/96, 1N6479-E3/96, and BYM10-100-E3/97 are supplied in Tape & Reel format. GL41B-E3/96 and BYM10-100-E3/96 are supplied in Cut Tape & Digi-Reel® format.

For Maximum Inventory Availability: GL41B-E3/96 offers the highest stock level at 12,100 pieces, followed by BYM10-100-E3/96 at 6,814 pieces and 1N6479-E3/96 at 6,300 pieces.

Frequently Asked Questions (FAQ)

Q: Can GL41B/54 be directly replaced with any of the listed substitute parts?

A: All substitute parts are electrically equivalent to GL41B/54 across all critical rectifier parameters: reverse voltage (100 V), average rectified current (1 A), forward voltage (1.1 V @ 1 A), recovery speed (standard >500ns), reverse leakage (10 µA @ 100 V), and capacitance (8 pF @ 4V, 1MHz). All parts use identical DO-213AB surface mount packaging. Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between Standard and Avalanche technology in these diodes?

A: Both technology types maintain identical electrical specifications for this product category. The technology designation reflects the internal design approach but does not alter the rated parameters provided in the specification table. Selection between standard and avalanche technology is determined by application-specific requirements not specified in the electrical parameters.

Q: Why does GL41B/54 show RoHS non-compliant status while substitutes are ROHS3 compliant?

A: RoHS compliance status reflects the manufacturing date and regulatory certification of each specific part number. Substitute parts with E3 designations and /96 or /97 suffixes are manufactured to current ROHS3 standards. The GL41B/54 without these designations represents an earlier production variant. Electrical performance is identical across all variants.

Q: What packaging format should I select for automated assembly?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. GL41BHE3/96, 1N6479-E3/96, and BYM10-100-E3/97 are supplied in Tape & Reel format. Cut Tape (CT) & Digi-Reel® format (GL41B-E3/96 and BYM10-100-E3/96) is suitable for semi-automated or manual assembly processes.

Q: Are all substitute parts from the same manufacturer?

A: All substitute parts are manufactured by Vishay General Semiconductor - Diodes Division, identical to the primary GL41B/54 part. All parts belong to the SUPERECTIFIER® series.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and have unlimited shelf life under standard storage conditions.

Q: Can I use BYM10-100-E3/96 or BYM10-100-E3/97 (Avalanche technology) as direct replacements for GL41B/54 (Standard technology)?

A: From an electrical specification standpoint, all parameters are identical. The avalanche technology designation indicates a different internal design approach, but the rated electrical characteristics remain the same. Application compatibility depends on whether the circuit design specifically requires or excludes avalanche diode characteristics, which is not specified in the provided parameters.
