Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE8.2 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 7.02V
• Voltage - Clamping (Max) @ Ipp: 12.1V to 12.71V range
• Power - Peak Pulse: 600W or 500W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature: -55°C ~ 175°C (TJ)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed below meet these criteria and are classified as active products, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

P6KE8.2A (Taiwan Semiconductor Corporation) and P6KE8.2A-TP (Micro Commercial Co) are direct functional equivalents with identical reverse standoff voltage (7.02V), clamping voltage (12.1V), and power rating (600W). Both are active products with ROHS3 compliance and full temperature range specifications (-55°C ~ 175°C). P6KE8.2A offers higher peak pulse current (52A) compared to P6KE8.2A-TP (50A), providing additional margin in transient suppression applications.

P6KE8V2A-B (Diodes Incorporated) maintains identical electrical parameters and includes ROHS3 compliance with full operating temperature range, ensuring long-term supply availability.

Secondary Substitute (Marginal Differences):

SAC7.0-E3/54 (Vishay General Semiconductor - Diodes Division) operates at a slightly lower reverse standoff voltage (7V versus 7.02V) and reduced peak pulse power (500W versus 600W). This part is suitable for applications where the lower power rating and voltage tolerance are acceptable. The clamping voltage (12.6V) remains within acceptable range for general-purpose protection circuits.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. P6KE8V2A lacks documented operating temperature range; verify thermal requirements before selection if operation near temperature extremes is required.

Frequently Asked Questions (FAQ)

Q: Can P6KE8.2A directly replace P6KE8.2 in existing circuits?

A: Yes. P6KE8.2A maintains identical reverse standoff voltage (7.02V), equivalent clamping voltage (12.1V), and matching 600W power rating. The through-hole DO-15 package is mechanically compatible. No circuit modifications are required.

Q: What is the difference between P6KE8.2A and P6KE8.2A-TP?

A: Both parts share identical electrical specifications (7.02V standoff, 12.1V clamping, 600W power). P6KE8.2A-TP is supplied in cut tape (CT) packaging, while P6KE8.2A is supplied in bulk. Peak pulse current differs slightly (50A versus 52A). Selection depends on packaging requirements and procurement volume.

Q: Is SAC7.0-E3/54 a suitable replacement?

A: SAC7.0-E3/54 is functionally compatible but operates at reduced specifications: 7V reverse standoff (versus 7.02V) and 500W peak pulse power (versus 600W). It is suitable for applications where these lower ratings meet circuit requirements. The clamping voltage (12.6V) remains within acceptable tolerance for general-purpose transient suppression.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitutes except P6KE8V2A are documented as ROHS3 compliant. P6KE8V2A compliance status is not specified in available data; confirm with the supplier if ROHS3 certification is required.

Q: What is the operating temperature range for these parts?

A: P6KE8.2A, P6KE8.2A-TP, P6KE8V2A-B, and SAC7.0-E3/54 all operate across -55°C to 175°C (TJ). P6KE8V2A does not specify an operating temperature range; verify thermal specifications with the manufacturer if operation at temperature extremes is required.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All substitute parts are active products with established supply chains and compliance certifications. Selection should be based on specific application requirements, including voltage tolerance, power dissipation margin, and thermal operating conditions. Consult component datasheets for detailed electrical characteristics and derating curves.
