MMBD4448HAQW-TP Equivalent & Substitute Parts

Part Overview

The MMBD4448HAQW-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as a 2 Pair Common Anode device in a 6-TSSOP (SOT-363) surface mount package. This component is designed for fast recovery rectification applications requiring 80 V reverse voltage capability and 250 mA average rectified current per diode. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and component availability across multiple manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMBD4448HAQW-TP 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 Equivalence Criteria:

• Diode configuration: 2 Pair Common Anode
• Maximum reverse voltage (Vr): 80 V
• Average rectified current per diode (Io): 250 mA
• Maximum forward voltage (Vf): 1.25 V @ 150 mA
• Reverse recovery time (trr): 4 ns
• Reverse leakage current: 100 nA @ 70 V
• Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Package type: 6-TSSOP, SC-88, SOT-363
• Mounting type: Surface Mount
• Supplier device package: SOT-363

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria and share the same base product number (MMBD4448), differing only in manufacturer designation and operating temperature range specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—MMBD4448HAQW-TP (Micro Commercial Co), MMBD4448HADW-7-F (Diodes Incorporated), and MMBD4448HAQW-7-F (Diodes Incorporated)—are parametrically equivalent and maintain Active product status. Each part is ROHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating.

The substitute parts from Diodes Incorporated provide an extended operating temperature range of -65°C to 150°C compared to the main part's maximum junction temperature specification of 150°C. This extended range does not restrict substitution in applications operating within the main part's specified temperature limits.

Selection between these parts should be based on:

• Availability and lead time from respective manufacturers and distributors
• Supply chain requirements and preferred vendor relationships
• Packaging format (Tape & Reel for all listed parts)
• Application temperature operating range (extended range of substitute parts supports broader environmental conditions)

All parts are suitable for direct substitution in circuit designs requiring 80 V, 250 mA general-purpose diode array functionality in SOT-363 surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Can MMBD4448HADW-7-F or MMBD4448HAQW-7-F be used as direct replacements for MMBD4448HAQW-TP?

A: Yes. Both Diodes Incorporated parts are parametrically equivalent to the Micro Commercial Co part across all critical electrical specifications (reverse voltage, forward voltage, current ratings, recovery time, and leakage current) and share identical package geometry (6-TSSOP, SC-88, SOT-363). All three parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between MMBD4448HADW-7-F and MMBD4448HAQW-7-F?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. The difference lies in the manufacturer's internal designation suffix (-HADW-7-F versus -HAQW-7-F), which does not affect functional performance or compatibility. Both are suitable substitutes for the main part.

Q: Does the extended operating temperature range (-65°C to 150°C) of the Diodes Incorporated parts affect substitution suitability?

A: No. The extended temperature range of the substitute parts is a superset of the main part's maximum junction temperature specification (150°C). Applications operating within the main part's specified temperature limits are fully compatible with the substitute parts.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. MMBD4448HAQW-TP, MMBD4448HADW-7-F, and MMBD4448HAQW-7-F are all supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No additional handling or storage precautions are required beyond standard component storage practices.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical SOT-363 package geometry and pin configuration (6-TSSOP, SC-88). PCB footprints, solder reflow profiles, and assembly processes are identical across all parts.
