DL4001-13 Equivalent & Substitute Parts

Part Overview

The DL4001-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 50 V DC reverse voltage and 1 A average rectified current in a surface mount MELF (DO-213AB) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the surface mount MELF package format.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DL4001-13 are qualified based on the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Package / Case: DO-213AB, MELF (Glass)
• Mounting Type: Surface Mount

Compatible Parameter Ranges:

• Voltage - Forward (Vf) (Max) @ If: ≤ 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: ≤ 5 µA @ 50 V (lower values acceptable)
• Capacitance @ Vr, F: ≤ 20 pF @ 4V, 1MHz (higher values acceptable within circuit tolerance)
• Operating Temperature - Junction: ≥ -55°C to ≤ 150°C minimum range
• Technology: Standard
• Speed: Standard or Fast Recovery acceptable

Both substitute parts meet these criteria and are manufactured by Vishay General Semiconductor - Diodes Division in the SUPERECTIFIER® series.

Parameter Comparison

Engineering Selection Recommendations

BYM12-50-E3/96 is suitable for applications requiring improved performance characteristics. This part features fast recovery time (≤ 500ns) compared to the standard recovery of the DL4001-13, lower forward voltage drop (1 V @ 1 A), and extended operating temperature range (-65 to 175°C). The BYM12-50-E3/96 is ROHS3 compliant and maintains active product status. Packaging is provided in Cut Tape (CT) & Digi-Reel® format.

GL41A-E3/97 provides direct electrical equivalence to the DL4001-13 with identical forward voltage specification (1.1 V @ 1 A) and standard recovery characteristics. This part offers lower junction capacitance (8 pF @ 4V, 1MHz), extended operating temperature range (-65 to 175°C), and ROHS3 compliance. The GL41A-E3/97 is supplied in Tape & Reel (TR) packaging and maintains active product status with higher inventory availability.

Both substitute parts are electrically compatible with the DL4001-13 across all mandatory parameters. Selection between BYM12-50-E3/96 and GL41A-E3/97 depends on specific application requirements regarding recovery speed, forward voltage characteristics, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can BYM12-50-E3/96 and GL41A-E3/97 be used interchangeably with DL4001-13?

A: Both parts meet the mandatory electrical specifications (50 V reverse voltage, 1 A average rectified current) and share the identical DO-213AB MELF surface mount package. They are electrically compatible for direct substitution. Selection between them depends on application-specific requirements for recovery speed and forward voltage characteristics.

Q: What is the difference in recovery speed between the substitute parts?

A: BYM12-50-E3/96 features fast recovery (≤ 500ns), while GL41A-E3/97 maintains standard recovery (>500ns), matching the original DL4001-13 specification. Fast recovery reduces switching losses in high-frequency applications but may introduce additional noise in sensitive circuits.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both BYM12-50-E3/96 and GL41A-E3/97 are ROHS3 compliant, whereas the original DL4001-13 is RoHS non-compliant. This compliance improvement may be required for new designs or regulatory requirements.

Q: How do the forward voltage specifications compare?

A: BYM12-50-E3/96 specifies 1 V @ 1 A (lower than DL4001-13), while GL41A-E3/97 specifies 1.1 V @ 1 A (identical to DL4001-13). Lower forward voltage reduces power dissipation in the diode.

Q: What are the packaging format differences?

A: BYM12-50-E3/96 is supplied in Cut Tape (CT) & Digi-Reel® format, while GL41A-E3/97 is supplied in Tape & Reel (TR) format. Both are surface mount packages suitable for automated assembly processes.

Q: Do the substitute parts support the same operating temperature range?

A: The DL4001-13 operates from -55 to 150°C. Both substitute parts extend this range to -65 to 175°C, providing improved thermal performance margin for demanding applications.

Q: What is the significance of junction capacitance differences?

A: GL41A-E3/97 exhibits lower junction capacitance (8 pF @ 4V, 1MHz) compared to DL4001-13 (15 pF @ 4V, 1MHz) and BYM12-50-E3/96 (20 pF @ 4V, 1MHz). Lower capacitance reduces switching transients and improves high-frequency performance in sensitive circuits.

Q: Are there inventory considerations for these substitutes?

A: GL41A-E3/97 maintains higher inventory availability (21,230 pcs) compared to BYM12-50-E3/96 (2,456 pcs), which may influence procurement timelines and lead times.
