SMD22PL-TP Equivalent & Substitute Parts

Part Overview

The SMD22PL-TP is an active Schottky diode manufactured by Micro Commercial Co, rated for 20V DC reverse voltage and 2A average rectified current in a surface mount SOD-123FL package. This component is designed for fast recovery rectification applications requiring low forward voltage drop and rapid switching characteristics. Equivalent and substitute parts are identified based on matching or exceeding electrical performance parameters while maintaining compatibility with the specified package footprint and thermal requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMD22PL-TP are selected based on the following criteria:

Primary Substitution Criteria:

• Technology: Schottky diode
• Voltage Rating: Equal to or greater than 20V DC reverse voltage
• Current Rating: Equal to or greater than 2A average rectified current
• Speed Characteristic: Fast recovery ≤ 500ns at > 200mA
• Mounting Type: Surface mount
• Package Compatibility: SOD-123F or SOD-123FL footprint
• Compliance: ROHS3 compliant, REACH unaffected

Substitution Logic: Parts are grouped into two categories based on voltage rating alignment. Parts rated at 20V match the primary voltage specification and provide direct replacement capability. Parts rated above 20V (such as 40V devices) provide enhanced voltage margin and are suitable for applications where higher reverse voltage withstand capability is beneficial, provided the package footprint remains compatible with the PCB layout.

Parameter Comparison

Engineering Selection Recommendations

PMEG2020EH,115 (Nexperia USA Inc.): This part provides direct electrical equivalence to the SMD22PL-TP with identical voltage and current ratings. The PMEG2020EH,115 features lower reverse leakage current (200 µA versus 500 µA) and maintains the same SOD-123F package footprint. This part carries AEC-Q100 automotive qualification, indicating enhanced reliability screening. The maximum junction temperature rating of 150°C exceeds the SMD22PL-TP specification. Packaging is available in Cut Tape and Digi-Reel formats. This substitute is suitable for direct replacement in applications where the original part is unavailable.

PMEG4020ER,115 (Nexperia USA Inc.): This part provides enhanced voltage rating at 40V DC reverse voltage while maintaining 2A current capacity. The forward voltage drop is superior at 490 mV compared to the SMD22PL-TP at 500 mV. Reverse leakage current is significantly lower at 100 µA. The package footprint differs (SOD-123W versus SOD-123FL), requiring PCB layout verification before implementation. This substitute is applicable in applications where higher reverse voltage margin is required or where the SOD-123W footprint is compatible with existing PCB design. Packaging is supplied in Tape & Reel format.

Both substitute parts maintain full ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can PMEG2020EH,115 be used as a direct replacement for SMD22PL-TP? A: Yes. Both parts share identical voltage (20V) and current (2A) ratings, operate with fast recovery characteristics, and use the SOD-123F package footprint. The PMEG2020EH,115 features improved reverse leakage performance and higher maximum junction temperature.

Q: What is the primary difference between PMEG2020EH,115 and PMEG4020ER,115? A: The PMEG2020EH,115 is rated for 20V reverse voltage, matching the SMD22PL-TP specification. The PMEG4020ER,115 is rated for 40V reverse voltage, providing higher voltage margin. The PMEG4020ER,115 uses a SOD-123W package instead of SOD-123F, which may require PCB layout changes.

Q: Is the SOD-123W package footprint compatible with SOD-123F PCB layouts? A: SOD-123W and SOD-123F are different package outlines. PCB layout verification is required before substituting PMEG4020ER,115 for the original part. Consult package datasheets for dimensional specifications.

Q: Do the substitute parts meet the same compliance standards as SMD22PL-TP? A: Yes. Both PMEG2020EH,115 and PMEG4020ER,115 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the SMD22PL-TP.

Q: What is the significance of lower reverse leakage current in the substitute parts? A: Lower reverse leakage current (200 µA for PMEG2020EH,115 and 100 µA for PMEG4020ER,115 versus 500 µA for SMD22PL-TP) indicates reduced parasitic current flow in reverse bias conditions, which can improve circuit efficiency and reduce power dissipation in certain applications.

Q: Are the substitute parts available in the same packaging formats as SMD22PL-TP? A: PMEG2020EH,115 is available in Cut Tape and Digi-Reel formats. PMEG4020ER,115 is supplied in Tape & Reel format. The original SMD22PL-TP is supplied in Tape & Reel format. Packaging format selection depends on assembly process requirements.

Q: What is the maximum junction temperature difference between the parts? A: SMD22PL-TP is rated to 125°C maximum junction temperature. Both substitute parts are rated to 150°C maximum junction temperature, providing 25°C additional thermal margin.
