Substitute Part Grouping Explanation

Substitute parts for the SS3P3LHM3_A/H are identified based on strict electrical and mechanical parameter matching within the Schottky diode rectifier category. The substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 3 A
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: TO-277, 3-PowerDFN

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The PMEG030V030EPDZ from Nexperia USA Inc. satisfies all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SS3P3LHM3_A/H and PMEG030V030EPDZ are active, automotive-grade Schottky diodes qualified to AEC-Q101 standards with ROHS3 compliance and MSL 1 moisture sensitivity ratings. Both devices meet the electrical and mechanical requirements for 30 V / 3 A surface mount rectification applications.

The PMEG030V030EPDZ exhibits improved electrical characteristics within the specified parameter range: forward voltage drop is reduced by 20 mV (450 mV versus 470 mV at 3 A), and reverse leakage current is lower by 100 µA (150 µA versus 250 µA at 30 V). The PMEG030V030EPDZ also supports a higher maximum junction temperature of 175°C compared to 150°C for the SS3P3LHM3_A/H.

Selection between these parts is determined by availability, lead time, cost, and specific application thermal requirements. Both parts are suitable for direct substitution in automotive and industrial rectification circuits operating within the specified electrical and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the PMEG030V030EPDZ be used as a direct replacement for the SS3P3LHM3_A/H?

A: Yes. Both devices are Schottky diodes rated for 30 V reverse voltage and 3 A average rectified current, qualified to AEC-Q101 automotive standards, and packaged in TO-277 / 3-PowerDFN surface mount form factors. Electrical and mechanical parameters are compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The PMEG030V030EPDZ has a lower forward voltage drop (450 mV versus 470 mV at 3 A), lower reverse leakage current (150 µA versus 250 µA at 30 V), and a higher maximum junction temperature rating (175°C versus 150°C). Both parts meet the same voltage and current specifications and automotive compliance requirements.

Q: Are the package configurations identical?

A: Both parts use TO-277 / 3-PowerDFN package classification. The supplier device packages differ: SS3P3LHM3_A/H uses TO-277A (SMPC), while PMEG030V030EPDZ uses CFP15. These are compatible surface mount configurations within the same package family.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the SS3P3LHM3_A/H and PMEG030V030EPDZ are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for automotive and industrial applications.

Q: What is the operating temperature range for each part?

A: The SS3P3LHM3_A/H operates from -55°C to 150°C junction temperature. The PMEG030V030EPDZ operates to a maximum junction temperature of 175°C, providing a 25°C higher thermal margin for high-temperature applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the electrical parameter variations. The lower forward voltage drop and reverse leakage of the PMEG030V030EPDZ may improve efficiency and reduce heat dissipation in rectification circuits. Both parts maintain the same voltage and current ratings and automotive qualification status.
