P6SMB82AT3 Equivalent & Substitute Parts

Part Overview

The P6SMB82AT3 is a transient voltage suppressor (TVS) diode manufactured by onsemi, designed for surface mount applications in the DO-214AA (SMB) package. This unidirectional zener diode provides 70.1V reverse standoff voltage with 113V maximum clamping voltage and 5.3A peak pulse current capability. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB82AT3 is determined by the following critical parameters:

Electrical Parameters (Primary Criteria):

• Voltage - Reverse Standoff: 70V to 70.1V
• Voltage - Breakdown (Min): 77.8V to 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A minimum
• Power - Peak Pulse: 600W minimum

Mechanical Parameters (Secondary Criteria):

• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

Compliance Parameters:

• RoHS Status: Compliant or non-compliant (application-dependent)
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are classified as either direct equivalents (matching all electrical specifications) or similar alternatives (meeting electrical requirements within acceptable tolerances while offering enhanced performance or improved availability).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitutes):

P6SMB82A (Eaton - Electronics Division) and SMBJP6KE82A-TP (Micro Commercial Co) are direct electrical equivalents with identical reverse standoff voltage (70.1V), breakdown voltage (77.9V), and clamping voltage (113V). Both are active products with RoHS compliance and available in Tape & Reel packaging. P6SMB82A offers the lowest operating temperature floor at -55°C, while SMBJP6KE82A-TP extends the upper temperature limit to 175°C.

Enhanced Performance Alternatives:

1KSMB82A (Taiwan Semiconductor Corporation) meets all electrical requirements with superior specifications: 8.8A peak pulse current (versus 5.3A) and 1000W power rating (versus 600W). This part provides design margin for transient protection and operates across -55°C to 175°C. All RoHS3 compliant.

Functional Equivalents (Voltage-Matched):

SMBJ70A (MDD), SMBJ70A-TR (STMicroelectronics), SMBJ70AE3/TR13 (Microchip Technology), and TV06B700J-G (Comchip Technology) maintain the 70V reverse standoff and 113V clamping specifications within acceptable tolerance. These parts are active, RoHS3 compliant, and available from multiple manufacturers. SMBJ70AE3/TR13 matches the original -65°C to 150°C temperature range.

Compliance Consideration:

The original P6SMB82AT3 is RoHS non-compliant. All substitute parts listed are RoHS3 compliant, meeting current regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can I use 1KSMB82A as a direct replacement for P6SMB82AT3?

A: Yes. 1KSMB82A meets all electrical requirements with enhanced current and power ratings (8.8A, 1000W versus 5.3A, 600W). The higher ratings provide additional design margin without affecting circuit compatibility. Both use DO-214AA (SMB) packaging and are surface mount compatible.

Q: What is the difference between P6SMB82A and SMBJP6KE82A-TP?

A: Both are direct electrical equivalents with 70.1V reverse standoff and 113V clamping voltage. P6SMB82A operates -55°C to 150°C, while SMBJP6KE82A-TP extends to 175°C. Selection depends on thermal requirements. Both are RoHS compliant and available in Tape & Reel packaging.

Q: Are SMBJ70A variants interchangeable with the original P6SMB82AT3?

A: SMBJ70A variants (MDD, STMicroelectronics, Microchip) are functionally equivalent with 70V reverse standoff (versus 70.1V) and 113V clamping voltage. The 0.1V difference is within acceptable tolerance for TVS diode applications. All variants use DO-214AA (SMB) packaging and are RoHS3 compliant. Selection among variants depends on availability and temperature range requirements.

Q: Does package compatibility affect substitution?

A: All substitute parts use DO-214AA or SMB package designation, which are mechanically and electrically equivalent. Surface mount footprints are identical, allowing direct PCB substitution without layout modifications.

Q: Why should I choose an active product over the obsolete P6SMB82AT3?

A: Active products ensure long-term availability, supply chain stability, and access to current manufacturing quality standards. All substitute parts listed are active with RoHS3 compliance, supporting regulatory requirements and design longevity.

Q: What is the significance of RoHS compliance for this part?

A: The original P6SMB82AT3 is RoHS non-compliant. All substitute parts are RoHS3 compliant, meeting EU and global regulatory requirements for new designs. For legacy systems, RoHS non-compliant alternatives may be available, but RoHS compliant substitutes are recommended for new procurement.
