Substitute Part Grouping Explanation

Substitution for the P6SMB150AHE3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 128V
• Voltage - Breakdown (Min): 143V
• Voltage - Clamping (Max) @ Ipp: 207V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Type: Zener, Unidirectional
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The substitute part P6SMB150AHE3_B/I maintains identical electrical performance specifications and mechanical compatibility while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB150AHE3_B/I is the direct equivalent substitute for the obsolete P6SMB150AHE3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, mechanical compatibility, and automotive-grade qualifications including AEC-Q101 certification. The substitute part maintains full compliance with ROHS3 and REACH requirements.

The primary distinction is product status: the main part is obsolete while the substitute is active, ensuring long-term availability and supply chain continuity. The packaging difference (bulk versus Tape & Reel) does not affect electrical or mechanical performance and represents a standard procurement variation.

Frequently Asked Questions (FAQ)

Q: Can P6SMB150AHE3_B/I be used as a direct replacement for P6SMB150AHE3_A/I?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including voltage ratings, current handling, package type, and operating temperature range. The substitute is the recommended choice due to active product status.

Q: What is the difference between the packaging options?

A: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Both use the same DO-214AA (SMB) surface mount package. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance.

Q: Are both parts automotive-grade qualified?

A: Yes. Both P6SMB150AHE3_A/I and P6SMB150AHE3_B/I carry automotive-grade classification with AEC-Q101 qualification, meeting automotive reliability and quality standards.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is a standard lifecycle designation. The substitute part P6SMB150AHE3_B/I provides equivalent functionality with active availability, making it the appropriate choice for new designs and ongoing procurement.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across applications.
