SE30AFDHM3/6B Equivalent & Substitute Parts

Part Overview

The SE30AFDHM3/6B is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 200 V DC reverse voltage with 1.4 A average rectified current in a DO-221AC (SlimSMA) package. The device is qualified to AEC-Q101 automotive standards and carries Active product status. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE30AFDHM3/6B are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1.4 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Reverse Recovery Time (trr): 1.5 µs
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Capacitance @ Vr, F: 19 pF @ 4V, 1MHz

Mechanical Parameters:

• Package / Case: DO-221AC, SMA Flat Leads
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 175°C

Compliance Parameters:

• Series: eSMP®
• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts maintain identical electrical performance, thermal operating range, and package configuration. Automotive-grade qualification (AEC-Q101) is preserved across all listed substitutes.

Parameter Comparison

Engineering Selection Recommendations

SE30AFDHM3/6B (Primary Part) The SE30AFDHM3/6B is the primary reference part with Active product status and full automotive qualification (AEC-Q101). Current inventory is 1092 pieces. This part is suitable for applications requiring automotive-grade rectifier diodes with 200 V reverse voltage and 1.4 A average rectified current in surface mount DO-221AC packaging.

SE30AFDHM3/6A (Recommended Substitute) The SE30AFDHM3/6A is the preferred substitute, offering identical electrical specifications and mechanical compatibility. This part maintains full automotive qualification (AEC-Q101) and carries higher inventory availability at 14,881 pieces. All electrical parameters, thermal operating range, and package configuration are equivalent to the main part. The difference in part number suffix reflects manufacturing or supply chain designation only.

SE30AFD-M3/6A (Alternative Substitute) The SE30AFD-M3/6A provides parametric equivalence across all electrical and mechanical specifications. This part carries Active product status with inventory of 15,264 pieces. The primary distinction is the absence of specified automotive grade and AEC-Q101 qualification in the provided data. This part is suitable for non-automotive applications or where automotive qualification is not a design requirement. All electrical performance characteristics remain identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can SE30AFD-M3/6A be used in place of SE30AFDHM3/6B in automotive applications?

A: The SE30AFD-M3/6A provides identical electrical and mechanical specifications. However, the main part (SE30AFDHM3/6B) and SE30AFDHM3/6A carry explicit AEC-Q101 automotive qualification. If automotive qualification is a design requirement, use SE30AFDHM3/6A. If automotive qualification is not required, SE30AFD-M3/6A is electrically and mechanically compatible.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-221AC (SlimSMA) package with SMA flat leads and surface mount configuration. PCB layout and reflow soldering parameters remain unchanged across all substitutes.

Q: What is the difference between the part number suffixes?

A: The suffixes (M3/6A, M3/6B, DHM3/6A, DHM3/6B) reflect manufacturing designations or supply chain variants. All electrical and mechanical parameters remain identical within each parametric group.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

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

A: Yes, within the constraints of your design requirements. If automotive qualification (AEC-Q101) is mandatory, use SE30AFDHM3/6B or SE30AFDHM3/6A. For non-automotive applications, all three parts are electrically and mechanically interchangeable.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -55°C to 175°C for all three parts, supporting both industrial and automotive temperature environments.
