MMBD4148TW-7 Equivalent & Substitute Parts

Part Overview

The MMBD4148TW-7 is a diode array containing three independent general-purpose rectifier diodes rated for 75 V DC reverse voltage and 150 mA average rectified current per diode. Manufactured by Diodes Incorporated, this component is packaged in a 6-TSSOP (SC-88, SOT-363) surface mount configuration. The MMBD4148TW-7 is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for continued circuit design and production support.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the MMBD4148TW-7 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Diode Configuration: 3 Independent
• Voltage - DC Reverse (Vr) (Max): 75 V
• Current - Average Rectified (Io) (per Diode): 150 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 4 ns
• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Substitute parts are classified into two categories:

Direct Manufacturer Substitutes: Parts manufactured by Diodes Incorporated with identical part number structure and specifications, differing only in packaging format (Tape & Reel) or compliance status.

Parametric Equivalents: Parts from alternative manufacturers (Panjit International Inc., Micro Commercial Co) that meet all critical electrical and mechanical parameters within specified tolerances, enabling functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

MMBD4148TW-7-F is the primary direct substitute for the MMBD4148TW-7. Both components are manufactured by Diodes Incorporated and share identical electrical specifications. The MMBD4148TW-7-F differs only in packaging format (Tape & Reel versus bulk) and compliance status (ROHS3 Compliant versus RoHS non-compliant). This part is currently active with 20,200 units in stock, providing immediate availability for production requirements.

BAS16TW-7-F is a parametric equivalent manufactured by Diodes Incorporated. All critical electrical parameters match the original specification, including reverse voltage, forward voltage, current rating, and reverse recovery time. The BAS16TW-7-F is based on the BAS16 product line rather than the MMBD4148 line, but maintains full functional compatibility. This part is ROHS3 compliant and has the highest inventory availability at 155,100 units.

MMBD4148TW-TP is a manufacturer-recommended substitute produced by Micro Commercial Co. Electrical specifications are identical to the original part with the exception of operating temperature range (-55°C to 150°C versus -65°C to 150°C). This represents a narrower lower temperature limit. The part is ROHS3 compliant and active with 8,306 units in stock.

BAS16TW_R1_00001 is a parametric equivalent manufactured by Panjit International Inc. This part meets all critical specifications with two noted differences: reverse leakage current is specified at 2.5 µA @ 75 V (versus 1 µA for the original), and operating temperature range is -55°C to 150°C. The part is ROHS3 compliant with 12,137 units in stock.

For applications requiring the lowest operating temperature specification (-65°C), the MMBD4148TW-7-F is the appropriate selection. For applications with standard temperature requirements (-55°C minimum), all four substitute parts are functionally equivalent. Selection among these alternatives should consider inventory availability, compliance requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can MMBD4148TW-7-F be used as a direct replacement for MMBD4148TW-7?

A: Yes. The MMBD4148TW-7-F is a direct substitute manufactured by Diodes Incorporated with identical electrical specifications. The primary differences are packaging format (Tape & Reel versus bulk) and RoHS compliance status (ROHS3 Compliant). Both parts are functionally interchangeable in circuit applications.

Q: What is the difference between MMBD4148TW-7 and BAS16TW-7-F?

A: Both parts share identical electrical specifications: 75 V reverse voltage, 150 mA current rating, 1.25 V forward voltage, and 4 ns reverse recovery time. The difference lies in the product line designation (MMBD4148 versus BAS16) and manufacturer base product number. BAS16TW-7-F is manufactured by Diodes Incorporated and is functionally equivalent for all circuit applications.

Q: Are there temperature range differences between substitute parts?

A: Yes. The MMBD4148TW-7 and MMBD4148TW-7-F specify an operating temperature range of -65°C to 150°C. The MMBD4148TW-TP and BAS16TW_R1_00001 specify -55°C to 150°C, representing a 10°C higher minimum operating temperature. Applications requiring operation below -55°C must use MMBD4148TW-7-F.

Q: What is the reverse leakage current specification for each part?

A: MMBD4148TW-7, MMBD4148TW-7-F, BAS16TW-7-F, and MMBD4148TW-TP all specify 1 µA @ 75 V reverse leakage current. BAS16TW_R1_00001 specifies 2.5 µA @ 75 V, which is within acceptable parametric equivalence for general-purpose rectifier applications.

Q: Is the SOT-363 package identical across all substitute parts?

A: Yes. All substitute parts use the 6-TSSOP, SC-88, SOT-363 surface mount package. Pin configuration and PCB footprint are identical, enabling direct board-level substitution without layout modifications.

Q: What is the RoHS compliance status of each part?

A: The original MMBD4148TW-7 is RoHS non-compliant. All substitute parts (MMBD4148TW-7-F, BAS16TW-7-F, MMBD4148TW-TP, and BAS16TW_R1_00001) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Which substitute part has the highest inventory availability?

A: BAS16TW-7-F has the highest inventory with 155,100 units in stock, followed by MMBD4148TW-7-F with 20,200 units, BAS16TW_R1_00001 with 12,137 units, and MMBD4148TW-TP with 8,306 units.

Q: Can BAS16TW_R1_00001 be used in applications requiring 1 µA reverse leakage specification?

A: BAS16TW_R1_00001 specifies 2.5 µA @ 75 V reverse leakage current. Applications with strict leakage current requirements below 2.5 µA must use MMBD4148TW-7-F, BAS16TW-7-F, or MMBD4148TW-TP, which all specify 1 µA maximum.

Q: Are all substitute parts suitable for high-frequency switching applications?

A: All parts are classified as small signal diodes with 4 ns reverse recovery time, suitable for general-purpose rectification and switching applications within the specified current and voltage ratings. The reverse recovery time specification is identical across all parts.
