MP6KE8.2AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE8.2AE3 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient protection applications. This component features a 7.02V reverse standoff voltage with a 12.1V maximum clamping voltage and 50A peak pulse current capability in a T-18 axial through-hole package. The device is qualified to MIL-PRF-19500 military standards and maintains active product status. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate different packaging, compliance certifications, or operational temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6KE8.2AE3 is determined by equivalence in the following critical electrical parameters: Voltage - Reverse Standoff (7.02V typical), Voltage - Breakdown (7.79V minimum), Voltage - Clamping (12.1V maximum at Ipp), Current - Peak Pulse (50A minimum at 10/1000µs), and Power - Peak Pulse (600W). The substitute part P6KE8.2A meets these electrical specifications with identical voltage ratings and comparable peak pulse current (52A). Both parts are unidirectional Zener-type TVS diodes with through-hole mounting. Differences in package configuration (T-18 versus DO-204AC/DO-15), operating temperature range (-65°C to 150°C versus -55°C to 175°C), RoHS compliance status, and manufacturer do not preclude substitution when circuit board layout and compliance requirements permit the alternative package type.

Parameter Comparison

Engineering Selection Recommendations

The P6KE8.2A from Taiwan Semiconductor Corporation is a direct electrical equivalent to the MP6KE8.2AE3 and serves as a valid substitute when the following conditions are met:

Electrical Compatibility: The P6KE8.2A maintains identical voltage specifications (7.02V standoff, 7.79V breakdown, 12.1V clamping) and exceeds the peak pulse current requirement (52A versus 50A). Both devices deliver 600W peak pulse power and are classified as unidirectional Zener-type TVS diodes suitable for general-purpose transient protection.

Package Consideration: The substitute uses DO-204AC (DO-15) axial packaging instead of T-18 axial packaging. Both are through-hole components with axial lead configuration. PCB layout modifications may be required if the original design specifies T-18 package dimensions or lead spacing.

Temperature Range: The P6KE8.2A operates across -55°C to 175°C, which encompasses the upper portion of the MP6KE8.2AE3 operating range (-65°C to 150°C). Applications requiring operation below -55°C require the original MP6KE8.2AE3.

Compliance Status: The P6KE8.2A is ROHS3 compliant, whereas the MP6KE8.2AE3 is RoHS non-compliant. Selection of the substitute supports RoHS3 compliance requirements in new designs.

Military Qualification: The MP6KE8.2AE3 carries MIL-PRF-19500 qualification. The P6KE8.2A does not list military qualification. Applications requiring military-grade certification must use the original part.

Frequently Asked Questions (FAQ)

Q: Can the P6KE8.2A replace the MP6KE8.2AE3 in all applications?

A: The P6KE8.2A is electrically equivalent and suitable for general-purpose transient protection applications. Substitution is valid when PCB layout accommodates the DO-204AC (DO-15) package, operating temperature does not fall below -55°C, and military qualification is not required.

Q: What is the difference between T-18 and DO-204AC (DO-15) packages?

A: Both are through-hole axial packages for diodes. T-18 and DO-204AC (DO-15) differ in physical dimensions and lead spacing. PCB footprints are not interchangeable without layout modification. Verify package dimensions against PCB design specifications before substitution.

Q: Are the voltage ratings identical between these parts?

A: Yes. Both the MP6KE8.2AE3 and P6KE8.2A share identical reverse standoff voltage (7.02V), breakdown voltage (7.79V), and clamping voltage (12.1V). These parameters determine transient protection performance and are equivalent across both parts.

Q: Does the P6KE8.2A meet military standards?

A: The P6KE8.2A does not carry MIL-PRF-19500 qualification. The MP6KE8.2AE3 is qualified to this military standard. Applications requiring military-grade components must use the original MP6KE8.2AE3.

Q: What is the peak pulse current difference, and does it matter?

A: The P6KE8.2A is rated for 52A peak pulse current compared to 50A for the MP6KE8.2AE3. This 2A difference represents a 4% increase in current handling capability and does not reduce performance. The substitute provides equal or superior transient suppression.

Q: Can I use the MP6KE8.2AE3 in applications requiring RoHS3 compliance?

A: No. The MP6KE8.2AE3 is RoHS non-compliant. The P6KE8.2A is ROHS3 compliant and must be used for designs requiring RoHS3 certification.

Q: What is the operating temperature range difference?

A: The MP6KE8.2AE3 operates from -65°C to 150°C. The P6KE8.2A operates from -55°C to 175°C. The substitute covers a wider upper temperature range but does not extend to -65°C. Applications requiring operation below -55°C require the original part.
