P6SMB8.2A-E3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB8.2A-E3/52 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 7.02V reverse standoff voltage range with a 12.1V maximum clamping voltage and 49.6A peak pulse current rating. The device is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical performance parameters, package compatibility, and operational specifications within the DO-214AA (SMB) form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB8.2A-E3/52 are identified based on the following critical parameters:

Primary Matching Criteria:

• Reverse standoff voltage range: 7.0V to 8.55V
• Clamping voltage: 12.0V to 12.1V
• Peak pulse current: minimum 49.6A
• Package: DO-214AA (SMB) surface mount
• Power rating: 600W peak pulse
• Compliance: ROHS3 compliant, MSL 1

Substitution Logic: Parts are grouped as direct equivalents or functional substitutes when they maintain electrical performance within the specified voltage and current parameters while sharing identical package geometry and mounting characteristics. All identified substitutes operate within the general purpose TVS diode application category and maintain compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute): The P6SMB8.2A manufactured by Taiwan Semiconductor Corporation is the direct equivalent to the P6SMB8.2A-E3/52. This part maintains identical electrical specifications including 7.02V reverse standoff voltage, 12.1V clamping voltage, and 52A peak pulse current. Both parts share the same base product number (P6SMB8.2) and are ROHS3 compliant with MSL 1 rating. The primary difference is the operating temperature minimum of -55°C versus -65°C on the original part.

Functional Substitutes (Compatible Performance Range): The SMBJ7.0A-TP (Micro Commercial Co) and SMBJ7.0A (MDD) are functional substitutes with closely matched electrical performance. Both maintain 7V reverse standoff voltage, 12V clamping voltage, and 50A peak pulse current. These parts operate within the same voltage and current envelope as the primary part. The SMBJ7.0A-TP offers extended operating temperature range (-55 to 175°C) and is packaged in Tape & Reel format.

Alternative Substitute (Higher Current Rating): The SM6T10A manufactured by STMicroelectronics operates at a higher voltage level (8.55V reverse standoff, 18.6V clamping) with significantly higher peak pulse current (215A at 8/20µs pulse). This part is suitable only for applications requiring higher transient current suppression and is not recommended as a direct replacement without circuit analysis.

All identified substitutes maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and Active product status. Selection should be based on specific application requirements for operating temperature range, current handling capacity, and packaging format (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the P6SMB8.2A from Taiwan Semiconductor Corporation be used as a direct replacement for the P6SMB8.2A-E3/52? A: Yes. Both parts share identical electrical specifications (7.02V reverse standoff, 12.1V clamping, 52A peak pulse current) and the same base product number. The primary difference is the operating temperature minimum (-55°C versus -65°C). For applications operating above -55°C, this part is a direct equivalent.

Q: What is the difference between SMBJ7.0A and SMBJ7.0A-TP? A: Both parts have identical electrical specifications (7V reverse standoff, 12V clamping, 50A peak pulse current). The primary difference is packaging format: SMBJ7.0A-TP is supplied in Tape & Reel (TR) format, while SMBJ7.0A packaging is not specified. SMBJ7.0A-TP also offers an extended operating temperature range (-55 to 175°C).

Q: Why does the SM6T10A have a higher clamping voltage (18.6V) than the original part (12.1V)? A: The SM6T10A operates in a different voltage class (8.55V reverse standoff versus 7.02V) and is designed for higher transient current suppression (215A versus 49.6A). This part is not a direct replacement and should only be used when circuit requirements specifically call for higher voltage and current handling.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitute parts (P6SMB8.2A, SMBJ7.0A-TP, SMBJ7.0A, and SM6T10A) are ROHS3 compliant with MSL 1 moisture sensitivity rating, matching the compliance profile of the original P6SMB8.2A-E3/52.

Q: What packaging formats are available for these TVS diodes? A: All parts use the DO-214AA (SMB) surface mount package. Packaging supply formats vary: P6SMB8.2A-E3/52 and P6SMB8.2A are supplied in Tape & Reel (TR) format, SMBJ7.0A-TP is supplied in Tape & Reel (TR), SMBJ7.0A packaging format is not specified, and SM6T10A is supplied in Cut Tape (CT) and Digi-Reel® format.

Q: Can these parts be used interchangeably in automated assembly? A: Yes, all parts share identical DO-214AA (SMB) package geometry and surface mount mounting type, enabling direct substitution in automated pick-and-place assembly processes. Verify tape format compatibility with your assembly equipment specifications.
