P6SMB82AH Equivalent & Substitute Parts

Part Overview

The P6SMB82AH is an automotive-grade transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This unidirectional zener diode is designed for surface mount applications in the DO-214AA (SMB) package and provides transient voltage protection with a 70.1V reverse standoff voltage and 113V maximum clamping voltage. The device is actively produced and maintains AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified to support supply chain continuity, inventory optimization, and design flexibility while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB82AH are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Operating Temperature Range: -55°C to 150°C
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Current - Peak Pulse (10/1000µs): Substitute parts must maintain minimum 5.3A to support equivalent transient suppression performance within the specified clamping voltage envelope.

The P6SMB82A-AU_R1_000A1 from Panjit International Inc. meets all critical electrical parameters and maintains identical voltage specifications, temperature range, package configuration, and automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB82A-AU_R1_000A1 from Panjit International Inc. is a direct electrical and mechanical equivalent to the P6SMB82AH. Both devices maintain identical voltage specifications, thermal operating range, and automotive-grade qualification status. The peak pulse current specification of 5.3A in the substitute part remains within the functional envelope of the 113V clamping voltage and 600W peak pulse power rating, ensuring equivalent transient suppression performance.

Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, confirming suitability for automotive applications. The identical DO-214AA (SMB) surface mount package enables direct board-level substitution without layout or assembly modifications.

Selection between these parts may be based on inventory availability, lead time, supplier preference, or cost considerations, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB82A-AU_R1_000A1 be used as a direct replacement for the P6SMB82AH?

A: Yes. Both devices share identical voltage specifications (70.1V standoff, 77.9V breakdown, 113V clamping), operating temperature range (-55°C to 150°C), package configuration (DO-214AA, SMB), and automotive qualification (AEC-Q101). The peak pulse current difference (5.3A vs. 5.5A) does not affect functional equivalence within the specified clamping voltage and power envelope.

Q: Are there any package or mounting differences between these parts?

A: No. Both the P6SMB82AH and P6SMB82A-AU_R1_000A1 use the DO-214AA (SMB) surface mount package. No PCB layout, footprint, or assembly process modifications are required for substitution.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both devices carry AEC-Q101 automotive qualification and ROHS3 compliance. REACH status is unaffected for both parts, and moisture sensitivity level is rated at MSL 1 (Unlimited) for both.

Q: What is the significance of the 0.2A difference in peak pulse current?

A: The P6SMB82AH specifies 5.5A peak pulse current while the P6SMB82A-AU_R1_000A1 specifies 5.3A. Both maintain the same 113V clamping voltage and 600W peak pulse power rating. This variation remains within acceptable tolerance for transient voltage suppression applications and does not compromise device performance in equivalent circuit designs.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Electrical and mechanical equivalence permits interchangeable use in the same design and assembly process. However, component traceability and supplier documentation should be maintained according to applicable quality and regulatory standards.
