DB2X20600L Equivalent & Substitute Parts

Part Overview

The DB2X20600L is a Schottky diode manufactured by Panasonic Electronic Components, rated for 20 V DC reverse voltage and 1 A average rectified current in a SOD-123F surface mount package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB2X20600L is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 20 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: SOD-123F

Performance Considerations:

• Voltage - Forward (Vf) (Max) @ If: Lower values indicate improved efficiency
• Current - Reverse Leakage @ Vr: Lower values indicate reduced parasitic current
• Reverse Recovery Time (trr): Fast recovery characteristics (≤ 500 ns)
• Operating Temperature - Junction: Higher ratings provide thermal margin

The substitute parts identified meet or exceed the mandatory matching criteria. PMEG2010AEH,115 matches the 20 V / 1 A specification exactly. PMEG3010EH,115 exceeds the voltage rating at 30 V, providing backward compatibility. RBS1MM40ATR matches the 20 V / 1 A specification with alternative forward voltage characteristics.

Parameter Comparison

Engineering Selection Recommendations

PMEG2010AEH,115 (Nexperia USA Inc.)

This substitute provides direct electrical equivalence to the DB2X20600L with identical voltage and current ratings. The part is active in production with ROHS3 compliance and AEC-Q100 automotive qualification. Operating temperature rating of 150°C exceeds the original specification. Forward voltage of 430 mV @ 1 A is marginally lower than the original 450 mV, indicating improved efficiency characteristics. This part is suitable for direct replacement in applications where the original DB2X20600L was specified.

PMEG3010EH,115 (Nexperia USA Inc.)

This substitute provides a higher voltage rating of 30 V, exceeding the original 20 V specification. The part is active in production with ROHS3 compliance and AEC-Q100 automotive qualification. Operating temperature rating of 150°C exceeds the original specification. This part is suitable for applications where voltage margin is beneficial, though forward voltage of 560 mV @ 1 A is elevated compared to the original specification. Selection of this part introduces higher forward voltage losses and should be evaluated against circuit performance requirements.

RBS1MM40ATR (Rohm Semiconductor)

This substitute provides direct voltage and current equivalence to the DB2X20600L at 20 V / 1 A. The part is active in production with ROHS3 compliance. Forward voltage of 380 mV @ 1 A is lower than the original specification, indicating improved efficiency. Reverse leakage current of 400 µA @ 20 V is elevated compared to the original 100 µA specification. Operating temperature rating of 125°C matches the original specification. This part is suitable for replacement where lower forward voltage losses are prioritized.

Frequently Asked Questions (FAQ)

Q: Can PMEG3010EH,115 be used as a direct replacement for DB2X20600L?

A: PMEG3010EH,115 is electrically compatible as a substitute. The 30 V voltage rating exceeds the 20 V requirement of the original part, providing backward compatibility. However, the forward voltage specification of 560 mV @ 1 A is higher than the original 450 mV, which may affect circuit efficiency and thermal performance. Circuit validation is necessary to confirm acceptable performance.

Q: What is the primary difference between PMEG2010AEH,115 and RBS1MM40ATR?

A: Both parts match the 20 V / 1 A electrical specification of the DB2X20600L. PMEG2010AEH,115 features forward voltage of 430 mV @ 1 A and reverse leakage of 200 µA @ 20 V. RBS1MM40ATR features forward voltage of 380 mV @ 1 A and reverse leakage of 400 µA @ 20 V. Selection depends on whether lower forward voltage losses or lower reverse leakage current is prioritized in the application.

Q: Are all substitute parts available in the same package format?

A: All substitute parts are packaged in SOD-123F, matching the original DB2X20600L package specification. This ensures mechanical and electrical compatibility with existing printed circuit board layouts and assembly processes.

Q: What compliance certifications apply to the substitute parts?

A: PMEG2010AEH,115 and PMEG3010EH,115 are AEC-Q100 qualified automotive-grade components. All three substitute parts are ROHS3 compliant and carry REACH Unaffected status. The original DB2X20600L compliance information is not fully specified in the provided data.

Q: How do operating temperature ratings affect part selection?

A: PMEG2010AEH,115 and PMEG3010EH,115 are rated to 150°C junction temperature, exceeding the original 125°C specification. RBS1MM40ATR matches the original 125°C rating. Higher temperature ratings provide additional thermal margin in applications with elevated ambient or self-heating conditions.

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

A: Reverse leakage current affects standby power consumption and circuit performance at reverse bias conditions. The original DB2X20600L specifies 100 µA @ 20 V. PMEG2010AEH,115 specifies 200 µA, PMEG3010EH,115 specifies 150 µA, and RBS1MM40ATR specifies 400 µA. Applications sensitive to leakage current should prioritize PMEG2010AEH,115 or PMEG3010EH,115.
