• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 550 mV at rated current
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Mounting Type: Surface Mount
• Package / Case: SC-90, SOD-323F compatible

Substitute Parts Identified:

Group 1: Direct Electrical Upgrade (Higher Current Rating)

• PMEG2010AEJ,115 (Nexperia USA Inc.) – 20 V, 1 A rating with improved specifications

Group 2: Higher Voltage Rating (Same Current)

• RB550VM-30TE-17 (Rohm Semiconductor) – 30 V, 500 mA rating
• RB550VM-30FHTE-17 (Rohm Semiconductor) – 30 V, 500 mA rating with automotive qualification

All substitute parts maintain Schottky technology, fast recovery characteristics, surface mount configuration, and SOD-323F package compatibility.

Parameter Comparison

Engineering Selection Recommendations

PMEG2010AEJ,115 (Nexperia USA Inc.)

This substitute provides direct voltage compatibility at 20 V with an upgraded current rating of 1 A, exceeding the original 500 mA specification. The part maintains identical forward voltage characteristics at 550 mV and fast recovery speed. Operating temperature maximum is increased to 150°C. The device carries ROHS3 compliance and AEC-Q100 automotive qualification, indicating enhanced reliability and process control. This option is suitable for applications requiring the original 20 V specification with potential for higher current margin.

RB550VM-30TE-17 (Rohm Semiconductor)

This substitute provides a 30 V reverse voltage rating with maintained 500 mA current specification, offering increased voltage headroom over the original 20 V design. Forward voltage is 590 mV at 500 mA, representing a 40 mV increase. Operating temperature maximum is 150°C. The part is ROHS3 compliant with unlimited MSL rating. This option is suitable for applications where circuit voltage margins require higher reverse voltage rating without current increase.

RB550VM-30FHTE-17 (Rohm Semiconductor)

This substitute is functionally identical to RB550VM-30TE-17 with 30 V reverse voltage and 500 mA current rating. The primary distinction is automotive-grade qualification (AEC-Q101) and alternative packaging format (Cut Tape & Digi-Reel versus standard tape). This option is required for automotive applications or where AEC-Q101 certification is mandated by design specifications.

All three substitutes maintain surface mount configuration, SOD-323F package compatibility, and Schottky technology. Selection depends on application voltage requirements, current margin needs, and automotive qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can PMEG2010AEJ,115 directly replace DB2J20100L in all applications?

A: PMEG2010AEJ,115 is electrically compatible at the 20 V, 500 mA operating point. The 1 A current rating provides additional margin. Forward voltage remains at 550 mV. Physical package is identical (SOD-323F). Substitution is valid for non-automotive applications. Verify circuit design does not depend on the lower 125°C junction temperature limit of the original part.

Q: What is the difference between RB550VM-30TE-17 and RB550VM-30FHTE-17?

A: Both parts have identical electrical specifications: 30 V reverse voltage, 500 mA current, 590 mV forward voltage, and 150°C operating temperature. The primary difference is packaging format and automotive qualification. RB550VM-30FHTE-17 includes AEC-Q101 automotive qualification and is supplied in Cut Tape & Digi-Reel format. RB550VM-30TE-17 is supplied in standard Cut Tape format without automotive qualification.

Q: Can I use a 30 V rated diode in place of a 20 V rated diode?

A: Yes. A higher reverse voltage rating is a valid substitution provided all other parameters meet or exceed the original specification. The 30 V Rohm devices (RB550VM-30TE-17 and RB550VM-30FHTE-17) maintain the 500 mA current rating and fast recovery characteristics. Forward voltage increases to 590 mV, which must be evaluated in the specific circuit application.

Q: Are all substitute parts in the same physical package?

A: Yes. All substitute parts use SC-90, SOD-323F package configuration, identical to the original DB2J20100L. Surface mount placement and PCB footprint compatibility is maintained across all options.

Q: What is the significance of AEC-Q100 and AEC-Q101 qualifications?

A: AEC-Q100 and AEC-Q101 are automotive electronics qualification standards. PMEG2010AEJ,115 carries AEC-Q100 qualification. RB550VM-30FHTE-17 carries AEC-Q101 qualification. These certifications indicate the parts have undergone rigorous automotive-grade testing and reliability assessment. Use AEC-qualified parts when design specifications or end-use applications require automotive-grade components.

Q: How does reverse leakage current affect substitution?

A: Reverse leakage current is specified at different voltage and temperature conditions across the parts. DB2J20100L specifies 10 µA @ 10 V. PMEG2010AEJ,115 specifies 70 µA @ 20 V. Rohm parts specify 35 µA @ 30 V. Higher leakage current increases power dissipation and may affect circuit performance in high-impedance applications. Evaluate leakage specifications against circuit requirements.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level (MSL) 1 indicates the component has unlimited shelf life without special moisture control measures. All listed parts carry MSL 1 rating, indicating no special storage or handling requirements beyond standard component handling practices.

Q: Is the DB2J20100L still available from other sources?

A: The provided data indicates DB2J20100L is discontinued at DiGi Electronics with 4003 pieces in stock. Availability from other distributors is not specified in the provided information. Substitute parts listed are all active products with confirmed inventory availability.
