Substitute Part Grouping Explanation

Substitution for the P6SMB82AHE3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Package / Case: DO-214AA, SMB
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Type: Zener
• Series: P6SMB, TransZorb®

The substitute part P6SMB82AHE3_B/I maintains identical electrical specifications and mechanical compatibility. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB82AHE3_B/I is the direct substitute for the obsolete P6SMB82AHE3_A/I. Both parts are manufactured by Vishay and maintain identical electrical and mechanical specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support. Both parts meet automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance. The packaging difference (Tape & Reel format for the substitute) is a procurement consideration that does not affect electrical performance or board-level compatibility in DO-214AA (SMB) surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can P6SMB82AHE3_B/I be used as a direct replacement for P6SMB82AHE3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (70.1V standoff, 113V clamping), current ratings (5.3A peak pulse), power dissipation (600W), and operating temperature range (-65°C to 150°C). The substitute part is actively manufactured and supported.

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

A: The primary difference is product status. P6SMB82AHE3_A/I is obsolete, while P6SMB82AHE3_B/I is active. The substitute is supplied in Tape & Reel packaging format, whereas the main part uses standard packaging. Electrical specifications and DO-214AA (SMB) package dimensions are identical.

Q: Are there any compatibility concerns with surface mount assembly?

A: No. Both parts use the same DO-214AA (SMB) surface mount package with identical footprint and soldering requirements. Assembly processes and PCB layouts require no modification.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a supply format for automated assembly. Once removed from the carrier tape and soldered to the PCB, the component performs identically to standard packaging formats.

Q: Are both parts automotive-grade qualified?

A: Yes. Both P6SMB82AHE3_A/I and P6SMB82AHE3_B/I carry automotive-grade classification with AEC-Q101 qualification, meeting automotive reliability and quality standards.
