SZP6SMB82AT3G Equivalent & Substitute Parts

Part Overview

The SZP6SMB82AT3G is an active Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for surface mount applications in the DO-214AA (SMB) package. This unidirectional Zener-type TVS diode provides transient voltage suppression with a 70.1V reverse standoff voltage and 113V maximum clamping voltage. The part is AEC-Q101 qualified for automotive applications and maintains RoHS3 compliance. Equivalent and substitute parts are identified based on matching electrical characteristics, package compatibility, and operational specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SZP6SMB82AT3G are qualified based on the following criteria:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional
• RoHS Status: RoHS or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting these electrical and mechanical specifications are considered direct substitutes. Variations in peak pulse current above the minimum threshold (5.3A) and operating temperature ranges do not disqualify substitution eligibility when all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements, ensuring long-term availability and regulatory compliance. The SZP6SMB82AT3G and P6SMB82A-E3/52 both support the full automotive operating temperature range of -65 to 150°C with AEC-Q101 qualification (Littelfuse) or equivalent automotive-grade specifications. The P6SMB82A from Eaton operates within -55 to 150°C, which is suitable for most applications but does not extend to the lower temperature extreme of -65°C.

Peak pulse current specifications are equivalent across all parts, with P6SMB82A providing 5.4A and both Littelfuse and Vishay parts rated at 5.3A. This minor variation does not affect substitution eligibility. All parts are packaged in DO-214AA (SMB) surface mount format with identical electrical performance characteristics for voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can P6SMB82A from Eaton be used as a direct substitute for SZP6SMB82AT3G in automotive applications?

A: P6SMB82A meets all core electrical specifications and package requirements. However, its operating temperature range (-55 to 150°C) does not extend to -65°C. Use this part only if your application does not require operation below -55°C.

Q: What is the difference between P6SMB82A-E3/52 and P6SMB82A?

A: Both parts share identical electrical characteristics (70.1V standoff, 113V clamping, 5.3A peak pulse). P6SMB82A-E3/52 is the Vishay variant with full -65 to 150°C temperature range, while P6SMB82A is the Eaton variant with -55 to 150°C range. Package designation differs slightly (DO-214AA vs. SMB), but both are surface mount compatible.

Q: Are all substitute parts RoHS compliant?

A: Yes. SZP6SMB82AT3G and P6SMB82A-E3/52 are ROHS3 compliant. P6SMB82A is RoHS compliant. All three meet regulatory requirements for lead-free manufacturing.

Q: Does capacitance specification affect substitution?

A: The SZP6SMB82AT3G specifies 260pF @ 1MHz. Substitute parts from Eaton and Vishay do not provide capacitance data in the available specifications. This parameter does not disqualify substitution when all voltage, current, and package specifications align.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use identical DO-214AA (SMB) surface mount packaging with the same pin configuration and footprint, enabling direct PCB-level substitution without layout modifications.
