P6KE8V2A-B Equivalent & Substitute Parts

Part Overview

The P6KE8V2A-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection applications. This through-hole component operates across a wide temperature range (-55°C to 175°C) and is ROHS3 compliant with unlimited moisture sensitivity rating. The part is currently in active production status with 975 units in stock.

Equivalent and substitute parts are identified when electrical characteristics and mechanical compatibility align within acceptable tolerances for the application, allowing for component sourcing flexibility, inventory optimization, or supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE8V2A-B is determined by alignment of the following critical parameters:

Voltage - Reverse Standoff (Typ): 7.02V ± tolerance
Voltage - Clamping (Max) @ Ipp: 12.1V ± tolerance
Current - Peak Pulse (10/1000µs): 50A minimum
Power - Peak Pulse: 600W minimum
Mounting Type: Through Hole
Package / Case: DO-204AC, DO-15, or Axial equivalent
Operating Temperature Range: -55°C ~ 175°C minimum
Type: Zener, Unidirectional

Three substitute parts meet these criteria and are classified as direct equivalents or manufacturer-recommended alternatives.

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original P6KE8V2A-B.

P6KE8.2A-TP and P6KE8.2A provide electrical parameter matching identical to the main part (7.02V standoff, 12.1V clamping, 50A+ peak pulse current, 600W peak power). These are direct functional equivalents with no performance trade-offs.

SA7.0A and SAC7.0 operate within acceptable voltage and thermal ranges but exhibit reduced peak pulse current (43A and 38A respectively) and peak power ratings (500W). These parts are suitable for applications with lower transient energy requirements.

SAC7.0 carries REACH Affected status, requiring verification against specific application regulatory requirements. All other parts maintain REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can P6KE8.2A-TP be used as a direct replacement for P6KE8V2A-B?

A: Yes. P6KE8.2A-TP matches all critical electrical parameters: 7.02V reverse standoff voltage, 12.1V clamping voltage, 50A peak pulse current, and 600W peak power. Both are through-hole DO-15 package devices with identical operating temperature ranges and compliance certifications.

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

A: The primary difference is packaging format. P6KE8.2A-TP is supplied in Cut Tape (CT), while P6KE8.2A packaging is not specified. Electrical characteristics are identical. Selection depends on assembly process requirements.

Q: Can SA7.0A replace P6KE8V2A-B in all applications?

A: SA7.0A is compatible for applications tolerating reduced peak pulse current (43A versus 50A) and peak power (500W versus 600W). Voltage characteristics (7V standoff, 12V clamping) are within acceptable tolerance. Verify application transient energy levels before substitution.

Q: Why does SAC7.0 have higher clamping voltage (12.6V) than the main part (12.1V)?

A: SAC7.0 is manufactured by Littelfuse Inc. with different design specifications. The 0.5V difference in clamping voltage may affect circuit protection thresholds. Verify compatibility with circuit design margins before use.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant. SAC7.0 carries REACH Affected status, while all other parts are REACH Unaffected. Confirm regulatory requirements for your application region.

Q: What packaging options are available for these TVS diodes?

A: All parts use through-hole mounting in DO-204AC, DO-15, or Axial package configurations. Specific packaging availability varies by manufacturer and supplier. Verify packaging format with your component distributor.
