Substitute Part Grouping Explanation

Substitution of the ES1PDHM3/84A is determined by electrical and mechanical parameter equivalence across the eSMP® series. All identified substitute parts maintain identical specifications for voltage rating (200 V DC reverse), current rating (1 A average rectified), forward voltage drop (920 mV @ 1 A), reverse recovery time (25 ns), reverse leakage current (5 µA @ 200 V), junction capacitance (10 pF @ 4V, 1MHz), and package configuration (DO-220AA surface mount). All substitute parts operate within the same temperature range (-55°C to 150°C junction temperature) and share the same base product number (ES1). Substitutes are grouped into two categories: automotive-qualified parts (AEC-Q101) and standard industrial parts. The ES1PDHM3/84A and ES1PDHM3/85A are both automotive-qualified; ES1PD-M3/84A and ES1PD-M3/85A are standard industrial equivalents. All parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity classification.

Engineering Selection Recommendations

Selection among ES1PDHM3/84A and its substitutes is determined by application requirements and regulatory compliance mandates.

For automotive applications requiring AEC-Q101 qualification: ES1PDHM3/84A and ES1PDHM3/85A are the appropriate selections. Both parts carry automotive grade designation and AEC-Q101 qualification, meeting functional safety and reliability standards for automotive circuit protection and power conversion.

For industrial and consumer applications without automotive qualification requirements: ES1PD-M3/84A and ES1PD-M3/85A provide electrical and mechanical equivalence without automotive-specific qualification. These parts maintain identical electrical performance and package compatibility.

All four parts are active products with continuous manufacturing support. All parts are RoHS3 compliant and REACH unaffected, supporting environmental and regulatory compliance requirements. Moisture sensitivity level 1 (unlimited) classification indicates no special storage or handling requirements during assembly.

Frequently Asked Questions (FAQ)

Q: Can ES1PD-M3/84A be used as a direct replacement for ES1PDHM3/84A?

A: ES1PD-M3/84A is electrically and mechanically equivalent to ES1PDHM3/84A. Both parts share identical electrical specifications (200 V, 1 A, 25 ns recovery time) and DO-220AA package configuration. The primary difference is automotive qualification: ES1PDHM3/84A carries AEC-Q101 qualification while ES1PD-M3/84A does not. Selection depends on whether the application requires automotive-grade certification.

Q: What is the difference between ES1PDHM3/84A and ES1PDHM3/85A?

A: Both parts are automotive-qualified (AEC-Q101) and share identical electrical and mechanical specifications. The suffix designation (84A versus 85A) reflects internal manufacturing or tape reel configuration differences not affecting electrical performance or package compatibility. Both are direct substitutes.

Q: Are all substitute parts compatible with the same PCB layout and assembly process?

A: Yes. All four substitute parts use the DO-220AA surface mount package with identical pin configuration, footprint, and soldering requirements. PCB layout and assembly processes require no modification when substituting among these parts.

Q: Do these diodes require special handling or storage conditions?

A: No. All parts carry MSL 1 (Unlimited) moisture sensitivity level classification, indicating no moisture-related storage or handling restrictions during manufacturing and assembly.

Q: Which substitute part should be selected for new design qualification?

A: For automotive applications, ES1PDHM3/84A or ES1PDHM3/85A are appropriate selections due to AEC-Q101 qualification. For industrial applications, ES1PD-M3/84A or ES1PD-M3/85A provide equivalent electrical performance. Selection should align with application regulatory requirements and supply chain availability.
