Substitute Part Grouping Explanation

Substitute parts for the SE40PDHM3_A/I are identified through parametric equivalence. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 2.4 A
• Voltage - Forward (Vf) (Max) @ If: 1.05 V @ 4 A
• Reverse Recovery Time (trr): 2.2 µs
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Capacitance @ Vr, F: 28 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Supplier Device Package: TO-277A (SMPC)

Compliance & Status (Must Match):

• Product Status: Active
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Series: eSMP®

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SE40PDHM3_A/H is a direct parametric equivalent to the SE40PDHM3_A/I. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and supply chain considerations. Both devices maintain active product status and AEC-Q101 qualification, confirming suitability for automotive applications. The ROHS3 compliance and REACH unaffected status apply uniformly across both parts. The difference in part number suffix (_A/I versus _A/H) reflects manufacturing or supply chain designation without impact on electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SE40PDHM3_A/H be used as a direct replacement for SE40PDHM3_A/I?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, reverse voltage rating (200 V), average rectified current (2.4 A), forward voltage drop (1.05 V @ 4 A), reverse recovery time (2.2 µs), and package configuration (TO-277A SMPC). They are functionally interchangeable.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the TO-277, 3-PowerDFN package with surface mount configuration. PCB layout and reflow soldering parameters remain identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both SE40PDHM3_A/I and SE40PDHM3_A/H carry AEC-Q101 qualification and are rated for automotive applications across the operating temperature range of -55°C to 175°C.

Q: What does the part number suffix (_A/I versus _A/H) indicate?

A: The suffix designates manufacturing or supply chain origin. The electrical and mechanical specifications remain identical between the two variants.

Q: Are there any compliance or environmental differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. Identical package geometry and pin configuration allow direct substitution without PCB redesign.
