Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBD4448HSDW-TP is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode Configuration: 2 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) (per Diode): 250 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 4 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 70 V

Mechanical Compatibility Requirements:

• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount
• Supplier Device Package: SOT-363

Compliance & Certification:

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

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical and mechanical specifications) and Functional Alternatives (different device category with compatible package and voltage ratings).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MMBD4448HSDW-7-F

The MMBD4448HSDW-7-F is the recommended parametric equivalent for the MMBD4448HSDW-TP. This part is manufactured by Diodes Incorporated and maintains identical electrical specifications across all critical parameters: 80 V reverse voltage, 250 mA average rectified current, 1.25 V forward voltage at 150 mA, and 4 ns reverse recovery time. The device is housed in the same 6-TSSOP (SOT-363) surface mount package and is ROHS3 Compliant with unlimited moisture sensitivity rating. The primary difference is packaging format: MMBD4448HSDW-7-F is supplied in Cut Tape (CT) & Digi-Reel® format, whereas the main part is supplied in Tape & Reel (TR). Both formats are suitable for automated assembly processes. The part is currently Active with 12,387 units in stock.

Secondary Substitute: MMBD4448HSDW-7

The MMBD4448HSDW-7, also manufactured by Diodes Incorporated, provides identical electrical performance to the main part with the same 80 V reverse voltage, 250 mA current rating, and 4 ns reverse recovery time. This part is housed in the same 6-TSSOP (SOT-363) package. However, this part is Discontinued at DiGi Electronics and carries RoHS non-compliant status, making it unsuitable for new designs or applications requiring RoHS3 compliance. Inventory is limited to 925 units. This part should be selected only when legacy system compatibility is required and RoHS compliance is not mandated.

Functional Alternative: SDA004-7

The SDA004-7, manufactured by Diodes Incorporated, is a Transient Voltage Suppressor (TVS) diode array with a different device category and functional purpose compared to the main part. While it shares the same 80 V voltage rating and 6-TSSOP (SOT-363) package, it is configured as a Steering (Rail to Rail) TVS diode rather than a general-purpose rectifier diode array. The SDA004-7 is not a direct electrical equivalent and should be selected only when TVS protection functionality is required in the circuit design. This part is ROHS3 Compliant and currently Active with 39,806 units in stock.

Frequently Asked Questions (FAQ)

Q: Can MMBD4448HSDW-7-F be used as a direct replacement for MMBD4448HSDW-TP?

A: Yes. The MMBD4448HSDW-7-F is a parametric equivalent with identical electrical specifications and the same SOT-363 package. The only difference is the packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both formats are compatible with standard surface mount assembly equipment.

Q: What is the difference between the packaging formats (Tape & Reel versus Cut Tape & Digi-Reel®)?

A: Tape & Reel (TR) format supplies components on a continuous reel suitable for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® format provides components on cut tape segments, also compatible with automated assembly but with different handling and feeder requirements. Both formats result in identical component performance.

Q: Why is MMBD4448HSDW-7 listed as discontinued?

A: The MMBD4448HSDW-7 is marked as Discontinued at DiGi Electronics, indicating it is no longer actively produced or stocked by this distributor. Additionally, this part carries RoHS non-compliant status, which may restrict its use in applications requiring environmental compliance certifications. The MMBD4448HSDW-7-F should be selected for new designs.

Q: Is SDA004-7 a suitable replacement for MMBD4448HSDW-TP?

A: No. The SDA004-7 is a TVS diode array with a different functional purpose and device category. While it shares the same 80 V voltage rating and SOT-363 package, it is designed for transient voltage suppression rather than general-purpose rectification. Selection of SDA004-7 requires circuit redesign and is appropriate only when TVS protection is the intended function.

Q: What compliance certifications are important for component selection?

A: The MMBD4448HSDW-TP is ROHS3 Compliant and REACH Unaffected. When selecting substitutes, MMBD4448HSDW-7-F maintains these same certifications, making it suitable for applications with environmental compliance requirements. The MMBD4448HSDW-7 is RoHS non-compliant and should not be used in applications requiring RoHS3 certification.

Q: Are the operating temperature ranges identical across all substitute parts?

A: The main part MMBD4448HSDW-TP specifies a maximum junction temperature of 150°C. The parametric equivalents MMBD4448HSDW-7-F and MMBD4448HSDW-7 specify an operating temperature range of -65°C to 150°C, providing a wider lower temperature specification. Both ranges are compatible for standard industrial applications.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All listed parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.
