SMBJ5.0D-M3/I Equivalent & Substitute Parts

Part Overview

The SMBJ5.0D-M3/I is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface mount component is designed for general-purpose transient voltage suppression applications, offering a 5V reverse standoff voltage with a 9.1V maximum clamping voltage at peak pulse current. The part is actively manufactured and ROHS3 compliant. Substitute parts may be required due to packaging availability, inventory constraints, or specific supplier preferences while maintaining equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ5.0D-M3/I is permissible with parts that maintain the following critical electrical and mechanical parameters:

• Reverse Standoff Voltage: 5V (Typ)
• Unidirectional channel configuration: 1 channel
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Base Product Number: SMBJ5.0
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable variations within the substitute group include minor differences in clamping voltage (within the 9.1V to 9.2V range), peak pulse current (within 65.2A to 65.9A range), and packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), provided all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ5.0D-M3/I and SMBJ5.0A-E3/5B are active products from Vishay General Semiconductor - Diodes Division, manufactured within the same TransZorb® series. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The electrical parameters are functionally equivalent within acceptable tolerances for general-purpose TVS applications: reverse standoff voltage remains 5V, clamping voltage ranges from 9.1V to 9.2V, and peak pulse current ranges from 65.2A to 65.9A. Both components operate across the same temperature range (-55°C to 150°C) and share identical package specifications (DO-214AA, SMB). Selection between these parts should be based on packaging format availability and supply chain requirements, as the Cut Tape & Digi-Reel® format of the SMBJ5.0A-E3/5B may offer different handling and storage advantages compared to the Tape & Reel format of the main part.

Frequently Asked Questions (FAQ)

Q: Can SMBJ5.0A-E3/5B be used as a direct replacement for SMBJ5.0D-M3/I?

A: Yes. Both parts share identical electrical specifications for reverse standoff voltage (5V), operating temperature range (-55°C to 150°C), and package type (DO-214AA, SMB). Clamping voltage and peak pulse current variations fall within acceptable tolerances for equivalent performance in general-purpose TVS applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments or alternative reel formats, offering flexibility for lower-volume production or mixed-component orders. Both formats contain identical components in the same DO-214AA package.

Q: Are there any compliance or certification differences between these parts?

A: No. Both SMBJ5.0D-M3/I and SMBJ5.0A-E3/5B are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: What determines whether a part can substitute for SMBJ5.0D-M3/I?

A: Substitution is valid when the following parameters match: 5V reverse standoff voltage, 1 unidirectional channel, DO-214AA SMB package, surface mount mounting type, -55°C to 150°C operating temperature, ROHS3 compliance, and MSL 1 rating. Clamping voltage and peak pulse current must remain within the specified ranges (9.1V to 9.2V and 65.2A to 65.9A respectively).

Q: Can I mix packaging formats in the same production run?

A: Packaging format selection depends on your assembly process and equipment compatibility. Tape & Reel format is optimized for continuous automated pick-and-place systems, while Cut Tape & Digi-Reel® format offers flexibility for manual or semi-automated assembly. Verify your equipment specifications before mixing formats.
