MP6KE11AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE11AE3 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage transient protection applications. This unidirectional zener-type TVS diode features a 9.4V reverse standoff voltage with a 15.6V maximum clamping voltage and 38A peak pulse current capability. The component is qualified to MIL-PRF-19500 military standards and is currently in active production status with 714 units available in bulk packaging. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging or compliance requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6KE11AE3 is determined by electrical parameter equivalence and mechanical compatibility. The critical parameters that define substitutability are:

• Voltage - Reverse Standoff (Typ): 9.4V
• Voltage - Breakdown (Min): 10.5V
• Voltage - Clamping (Max) @ Ipp: 15.6V
• Current - Peak Pulse (10/1000µs): 38A
• Power - Peak Pulse: 600W
• Type: Zener
• Unidirectional Channels: 1
• Mounting Type: Through Hole

The P6KE11A manufactured by Taiwan Semiconductor Corporation meets all electrical parameter requirements and operates within the same voltage and current specifications. Both components share the same base product number (P6KE11) and are classified as general-purpose TVS diodes. The primary difference between these parts is the packaging format: the MP6KE11AE3 is supplied in bulk packaging with T-18 axial case, while the P6KE11A is supplied in Tape & Reel format with DO-15 axial case. Both packages are through-hole mounting configurations suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The P6KE11A is electrically equivalent to the MP6KE11AE3 across all critical transient voltage suppression parameters. Selection between these components should be based on the following criteria:

MP6KE11AE3 Selection Criteria:

• Military-grade qualification (MIL-PRF-19500) is required
• RoHS non-compliant applications are acceptable
• T-18 axial package footprint is specified in circuit design
• Bulk packaging format is suitable for procurement requirements

P6KE11A Selection Criteria:

• ROHS3 compliance is required for the application
• DO-15 axial package footprint is compatible with circuit design
• Tape & Reel packaging format is preferred for automated assembly
• Taiwan Semiconductor Corporation sourcing is acceptable

Both components are active products with confirmed inventory availability. The MP6KE11AE3 provides military-grade qualification, while the P6KE11A offers RoHS3 compliance. Package and packaging format differences require verification of circuit board layout compatibility and procurement workflow requirements prior to component substitution.

Frequently Asked Questions (FAQ)

Q: Are the MP6KE11AE3 and P6KE11A electrically interchangeable?

A: Yes. Both components are electrically equivalent across all specified parameters: 9.4V reverse standoff voltage, 10.5V minimum breakdown voltage, 15.6V maximum clamping voltage, 38A peak pulse current, and 600W peak pulse power. Both are unidirectional zener-type TVS diodes with single-channel configuration.

Q: What are the package differences between these parts?

A: The MP6KE11AE3 uses a T-18 axial package in bulk format, while the P6KE11A uses a DO-15 axial package in Tape & Reel format. Both are through-hole mounting configurations. Circuit board layout and lead spacing must be verified for compatibility with the specific package selected.

Q: Which part should be selected for military applications?

A: The MP6KE11AE3 is qualified to MIL-PRF-19500 military standards and is the appropriate selection for military-grade applications. The P6KE11A does not carry military qualification.

Q: What is the difference in RoHS compliance between these parts?

A: The MP6KE11AE3 is RoHS non-compliant, while the P6KE11A is ROHS3 compliant. Applications requiring RoHS compliance must use the P6KE11A.

Q: Can the P6KE11A be used as a direct replacement in existing designs using the MP6KE11AE3?

A: Electrical substitution is valid. However, the different package types (T-18 versus DO-15) require verification that the circuit board layout accommodates the DO-15 package footprint and lead spacing. Procurement and assembly processes must also be evaluated for compatibility with Tape & Reel packaging format.

Q: Are there inventory considerations when selecting between these parts?

A: The MP6KE11AE3 has 714 units available in bulk packaging. The P6KE11A has 1400 units available in Tape & Reel format. Procurement requirements and lead time considerations should be evaluated based on application demand and assembly workflow.
