Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ150AHE3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 150V
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Current - Peak Pulse (10/1000µs): 2.5A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C
• Package / Case: DO-214AA, SMB
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The SMBJ150AHE3_B/I is identified as the manufacturer-recommended substitute. Both parts share identical electrical specifications, automotive-grade classification, and AEC-Q101 qualification. The primary distinction is product status: the original part is obsolete, while the substitute is active. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series and maintain full compatibility in circuit applications requiring 150V standoff protection with 600W peak pulse capability.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ150AHE3_B/I is the direct equivalent for the obsolete SMBJ150AHE3_A/I. Selection of the substitute part is supported by:

• Identical electrical performance across all specified parameters
• Matching automotive-grade classification and AEC-Q101 qualification
• Active product status ensuring long-term availability and supply chain continuity
• Full compliance with ROHS3 and REACH requirements
• Identical thermal operating range and package footprint

For new designs or component replenishment, the SMBJ150AHE3_B/I is the appropriate selection. Existing designs using the SMBJ150AHE3_A/I can transition to the substitute without circuit modification or re-qualification, provided the original design validation included the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150AHE3_B/I be used as a direct replacement for SMBJ150AHE3_A/I?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute is the manufacturer-recommended replacement for the obsolete original part.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. SMBJ150AHE3_A/I is obsolete, while SMBJ150AHE3_B/I is active. Both are manufactured by Vishay within the TransZorb® series and share identical electrical specifications, package configuration, and automotive qualifications.

Q: Are there packaging differences between these parts?

A: The SMBJ150AHE3_B/I is supplied in Tape & Reel (TR) packaging. Both parts use the DO-214AA (SMB) package for surface mount assembly. Packaging format does not affect electrical performance or circuit compatibility.

Q: Is the substitute part qualified for automotive applications?

A: Yes. The SMBJ150AHE3_B/I carries automotive-grade classification and AEC-Q101 qualification, matching the original part's qualification status.

Q: What compliance certifications apply to the substitute part?

A: The SMBJ150AHE3_B/I is ROHS3 compliant and REACH unaffected, consistent with the original part's compliance profile.
